This is my 2007 335 i bmw and after pulling it out of winter storage, i noticed that there were a lot of lights on the dash. I mean pretty much. All the lights were on the dash. Now my beloved 335i can be a little finicky.

I will admit, but i'm sure there are owners of older bmws out there watching that can relate. I also have a mirror that decides to flip itself upside down, for no reason it's kind of weird, but as much as i'd like to think that these lights on the dash are just the car's way of saying hello or help we got to fix them. We're going to fix all of them in this video all while making my car a little bit faster. I think i'm being a little optimistic here and if all else fails, if i can't get all these lights to turn off, it's a very simple solution and it has to do with just living with them.

You know: that's it we're just going to live with them. We would never smash the cluster, we would never smash it out because it annoys us so much, no all right. So, let's get right into fixing a bunch of stuff, and i want to start off with the coolant light. And yes, one of these days, i'm going to clean this car - i have not touched it since buying it, i'm kind of saving it for a detail video, so i purposely don't want to clean it, but we got to fix this coolant light, because this is a New one i haven't messed with anything in the cooling system.

Look at all these rock chips for everybody - who's yelling at me, for sitting on my hood, i'm getting it painted it's going to be okay, so we want to check the coolant and before you do, that, you want to make sure that there's no pressure in the System so the car has been sitting for probably over an hour at this point, so no pressure, we squeeze some hoses we're good and i haven't seen any leaks on the ground. I haven't smelled any coolant at all and let's just see what we have yeah wow, that is really low, very, very low. So that kind of explains that. But we have to make sure that there's no leak because there's no sense in filling that up.

If it's just going to pour out all right, so first things first, i am going to fill up the washer fluid, because that light comes on and off all the time as well, and i need an empty bottle to mix my really expensive, bmw coolant with water. All right one light down that was nice and easy. It's about the cheapest light. You can turn off on any bmw.

Is the washer fluid warning light? It's like getting away with murder all right now, i'm gon na demonstrate how to not use a funnel and spill coolant everywhere. Oh look at that skills. How high can i go here? How high before i spill so this washer fluid bottle is halfway filled with water and we'll top it off with coolant 50 50 mix. That's what you want! Okay, there.

We go that's about as that's about as high as i go nice and pretty all right. Cool minimal spillage, not bad, no funnel no funnel no funnel no funnel. Okay! Already spilled. Let's see how high can i go? Oh yeah? Oh, this is getting dangerous.

I am going to get okay, okay, okay, okay, cool, look at that. It's got this little floaty deal in here. Pretty much tells us to stop, even though i just put some more in there all right, so it wasn't too bad. Well, actually, no! Well! That's how much that's how much we lost so that is kind of bad.

We don't want that, but it wasn't enough to overheat the engine or anything even close to that all right. So we got our bobber floating up here now before we just put this cap on and call it a day. We need to pressure test the system and to do that, we are going to use this gigantic pressure testing kit. So this isn't mine.

This is uh. My friend billy's here at mancuso collision custom they are being really really nice and letting me work on some of my cars here. While my garage is taken over by my v12 project, which i still have parts for um, but this is a really nice kit. It comes with like every fitting in the world, so we have to find the one for bmw.

I don't know which one that is, but uh we're gon na figure it out. Okay, eeny meeny, miny moe. Let's do this one! Oh it works yeah. I totally just got that right randomly i, i didn't try like 18 of these off camera now.

No, i knew it was this one, the whole time all right. So with that connected, we have a good seal. We are gon na pump this guy up to about 15 psi. That's roughly what this system runs at.

Let's see, does it say? No, it doesn't say, but that's about right, so we're gon na go 15. Okay right there, all right we're at about 15! So we're going to let that sit while we go fix a bunch of other stuff and it should hold uh, i mean we would see pretty much right away if it was going to lose pressure and then you may even see the leak. So this is an excellent way of actually pinpointing your coolant leak as well all right, while our coolant pressure tester, is doing its thing. We have to diagnose the check engine light and the abs light, so i've connected a battery charger and i finally get to show you my new tool.

I've been playing with this for about a week. It is the autel maxi sys maxis. Is that how you said that max is this elite um? So this is a very, very high level diagnostic tool which i haven't really gotten into on the channel. I honestly just been using a bunch of cheap stuff.

My mercedes star system has finally just completely died. I will get a new one of those and i will be also showing you this little guy here. The mhd tuner and i have a little android tablet that we're going to use to flash this car with a new tune for e85 and we're going to do a little bit of logging. It's pretty cool stuff and just to let you know, i'm not being paid by anybody to make this video it's just.

This is a car channel like we use tools and gadgets and products. So i have to show you - and i got to tell you the name of them so anyway, i'm just simply using this stuff to work on my car fix my car, just like i would like a normal person before we scan this car for codes with the Autel, i believe i have to disable the jb4 piggyback tuner, so there is a piggyback tuner underneath there somewhere in the dash that's connected to the car that came with the 335i. It's pretty cool i'll talk to you guys and show you some of the features here in a moment, but i think that we need to disable it. So, hang on a second, so we're going to press these two down see how the cluster does that little crazy thing, and now, let's see oh, did i already do it yeah.

It already did so everything's on zero, and then we hit that okay good. So now we have disabled that jb4 piggy back and i think now we can scan this car properly. So we do have a wireless multiplexer with the autel, so it just plugs in to your normal obd2 connector and then we're gon na pick out which kind of car we have and we'll hit read. Okay, so it read the vin.

This is the type of vehicle we have. Yes, okay, diagnosis, all right, so here all the codes in the engine computer. There are quite a few now a couple things to note. This car is currently running perfectly fine.

I put some fresh fuel in this like right towards the end of the winter. I had forgotten i'd left quite a bit of e85 left in the tank. It did misfire a few times once when i started it. So i am looking here.

We have several misfires cylinder, three, four, all right. Let's just take a look here and it'll. Tell you the criteria, what needs to happen for it to set that code it'll even give you some ideas of what's wrong. I don't think that there's anything wrong.

Okay, so we also have mixture control, so these are adaptation type of codes. This could be the bad fuel as well. This could be a vacuum leak, although i've looked everything over and we fixed some stuff a few videos ago. So i don't believe, that's a big deal and catalytic converter conversion.

That's got to be an efficiency code, catalyst system, efficiency below threshold. So i do have catalytic converters on this car, but they are high flow cats. When i replace the downpipes and i'm just going to go ahead and say they're, just not enough for the stock computer to not trip this code, so that is kind of unfortunate, because i'd have to figure out a way to code. That out.

Even though i do have catalytic converters on the car fuel pump plausibility, this does have a new direct injection pump um. So that's kind of a weird one, and this last coat is probably nothing so guys. None of these are current codes right now. So i think we can just blow these out.

The car is running perfectly fine. We know the misfires had to do with some old fuel back in the winter time. Uh adaptations we'll reset the adaptations for sure all right. So here we go we're going to reset adaptation values, so this is definitely something good to do.

Adaptations were reset okay, so these are reset also. So this is cool. We can actually change the idle speed. Do you want to change permanent adjustment? No, i don't really want to do it, but that's pretty cool that we can so this menu.

You can do everything program keys, reset the maintenance light uh battery when you replace the battery on some bmws. You have to kind of program that in there as well, let's take a look yeah, we're still basically right at 15.. It was right in the line. So it's been.

I don't know 30 40 minutes, that's totally acceptable, so i'm gon na say we don't have any leaks at all. It may have just been a little low when i bought the car and uh yeah. I guess i didn't check that i kind of figured i would have, but regardless we don't have any leaks right now, so we're not gon na go too crazy with this nothing on the ground. No weird smells passes the pressure test, so we are a-okay all right guys.

I messed up i'm new with this tool. I meant to only erase the codes in the dme and it looks like i erased all of the codes, because there's no way everything on an 07 bmw passes. So unfortunately, i can't show you the codes that were in the abs module, but fortunately for me this has been an ongoing issue since i bought the car. The abs light would come on sometimes within, like just five.

Ten minutes of driving then go away. Then come back a minute later, so very intermittent, and i scanned it a few months ago and it was one of the front speed. Sensors was tripping the code. So what i want to do now is remove those speed, sensors and see if there's any rust or debris in there, because sometimes that can cause an intermittent abs light.

Look at that no lights on the dash hang on oh wow! This is a very rare sight. Look at that, i i'm gon na take a picture as well. This is gon na be my new screen saver on my phone. So this is what happens when your abs ring basically shreds itself to pieces, usually due to rust.

So normally there's a ring right here around the axle. This is the e55. By the way, this is what i'm doing over here um, but the abs ring just shredded itself and there's bits and pieces everywhere. So the sensor that normally goes in there, which i have about right now, was basically just had a bunch of rust on the end of it.

Alright guys. So i have taken one of the abs sensors out and this isn't really that bad, but sometimes there can be a little bit of rust and corrosion build up, and this is magnetic at the end and stuff will stick to the end of the sensor. So, as you can see, we do have some of that going on here, and this has been a chicago car, i think its entire life. So i've seen this where you just need to kind of clean off your abs sensors every once in a while, and you can fix a light this way.

Another thing: that's kind of common with abs sensors is that the wiring the long leads see. This goes all over the place all the way over. Here too, they develop an open circuit on the inside and then usually when you turn the wheel, you'll get an abs light that will come on so just another method of diagnosis, but i think in this case we are going to clean these off. Sometimes it's just a matter of this i'll get a rag in here and make it really nice um.

We should be good all right, so i took this sensor out as well. It wasn't even as bad as that side, so i don't know if this is gon na fix anything. It really wasn't all that bad. So we will see what happens during our test drive, but first, i'm gon na upload the new tune, because you wan na have a battery charger connected for this.

So we'll do the tune. I'll show you some cool features, then we'll go get some e85 and take a few blasts and see what this thing feels like. So what we're going to be doing here is a back end map. So mhd is just another tuning type company and they came out with this little dongle right here and there are a bunch of good tunes out there.

So there's some people that write their own tunes and there's some tunes that are pretty well proven available on the forum. So i got this off of n54tech.com it's a forum. Many people have used these tunes and they are very well proven. So you go to that forum and there is a thread i'll leave it linked down below.

If you guys have one of these cars, you can save a bunch of different tune files. Now, there's good instructions on that thread in the forum i'll leave it linked down below for you guys, um, but basically these just designate what kind of car you have. What years and stuff like that, so i know for the 335i. We need this guy right here and then here are all of the maps.

Pretty cool so again in the thread. It'll explain all of this, so you know which one to pick for your car but hybrid means hybrid turbos, which i have on the way they just haven't arrived. Yet so, sooner or later i'll be uploading, a hybrid e85 tune, but they have a low timing. One with no spool there's all sorts of different variations, but what we're going to be doing here is we're going to be installing this guy the e85 tune, and this is meant for guys running over 40 ethanol, which i'll be doing okay.

So now we should be able to go here contacting the dme. We can also add an exhaust burble there's a few other options: uh we have, but let's go ahead and right full. This is going to take some time to do so. That's why you want to make sure you have that battery charger connected? You don't want your battery to go low in the middle of a flash all right, so it started doing its thing.

We have about 34 35 minutes left to go all right, so we're almost done turn off ignition still starts. That's a good sign. I should probably reset my maintenance indicator. I have a few bulbs out in the back.

Let's see optional exhaust burble okay, so we have exhaust verbal and then cold start noise reduction, launch control, rpm; okay, yes, oh no way! This is awesome. 2900. That sounds good. All right! We're gon na do one of these no way.

Look at all this stuff. All right guys, it's the next morning, i've driven 45 miles and we just get a light, bulb light on. Okay, oh, what are the chances? My taillight is broken. So that's what that is um, but no warning lights.

No abs light ever uh no check engine light. It runs great so at this point let's go get some b85 all right about five gallons of e85. This should roughly give us e50 something like that. So i've gone 18 miles with e85 mixed in and i have just been driving around having some fun.

Oh just roasting them. This thing is wicked guys. This is wicked if you saw my earlier 335i videos after i fixed a bunch of other issues. That seems to be the bulk of the content for this car um you'll know that it didn't do that before it.

Wouldn't just roast them all the way through second and into third. This thing is wicked: now, with this new mhd back end flash with the jb4, i know it's a mouthful and if you guys aren't around or if you're not familiar with these cars, let me just give you a couple just two minutes of your time here to Understand the coolness and the tunability of a car with the n54, because these are budget cars. This car was like six grand or you guys might remember better than i do. I think it was six or sixty five hundred dollars.

You can get them for like five. Six grand all day, long and coming from the m113k world for mercedes, i can really appreciate the tunability of this car with very, very little money. Oh this boost is insane okay, so, like i said right now, we are in sorry for the light guys. It's a beautiful day hang on.

Let me just turn around all right, so we're gon na turn around for potentially better lighting and because we have to auto-tune. I love it. I love it. I have faster cars than this, but i don't know what it is.

Maybe it's just the manual transmission, this lighting still kind of stinks. This thing is just a blast boost and manual transmission, just a perfect combination. I love it um, but anyway what i wanted to talk to you guys about before i turn the camera to the cluster. So you guys can see.

All of this is just how good of a value these cars are, and the modification market is amazing. So these cars have factory wideband o2 sensors, which is phenomenal, and if you pair that, with this jb4 tuner, which again i don't know anyone at jb4, it came with the car and you can get them used for like 150 bucks. So just the the budget, the value of modding, this car is crazy, but if you have the jb4, there are a bunch of safety features that you get with that. Okay right, all right, we're good we're good we're good we're, auto tuned! So with the jb4 comes with a bunch of safety features that are just so cool guys.

We don't see this in a lot of platforms of this era, and so this has an overboost protection. It knows the air fuel ratio, so if it goes too lean, it'll cut your boost, so you don't blow your engine. It won't allow you to boost very high when the engine is cold. So if you try to beat on it when you're not supposed to it, won't let you, then you can go into the cluster and change all sorts of stuff on the fly, and there is a nice little sheet here that i'll pop up on the screen, and This is something you can find on the jb4 website.

I believe i think i just grabbed it off of forum, but this will tell you how to customize your car through your steering wheel buttons, so you can set all sorts of different things like your shift. Light rpm and you'll get the hazards that'll flash. When you're supposed to shift. You can even program in a two-step which we can do with the mhd as well, but you can do that on the fly with your steering wheel, buttons just go up and down in rpm for your two-step uh.

You can change your gauges, so you can have your fuel gauge uh, be a boost gauge. You can have your oil temperature gauge, be an intake air temperature gauge they're kind of gimmicky - it's not very specific, but it's cool that you can do that and there's so many other features i could spend. You know probably five minutes talking about them, but the fact that you can do this all through your steering wheel, i think, is really really cool now, just so, where there's no confusion here, because it is a little confusing. I i'm new to this whole n54 world, but we also have an mhd tuner, which is a different thing altogether.

So basically, the jb4 comes with all sorts of different maps and they work fine, but mhd has their own tunes, which many people say just produce more power. They have more control over everything like ignition timing and fueling. So what people have come up with on the forums is the back end flash. So what you can do is you can keep the jb4 for all of its safety features and that's an actual piggyback module.

That is just you know it's in your car. It's under the dash so you're going to keep it there for all your safety features and for all the adjustability that you can do through the steering wheel controls. But now with the mhd, you are going to flash in their more updated tunes which are constantly being refined as well and updated, which is really cool also for kind of an older platform. So what we did here, we're still in tune number five, which is auto-tune, but now the mhd is going to kind of take over and kind of add its tuning to it to make more power, and i can tell you right now that it definitely makes more Power than just the regular jb4 tune without this back end flash as well little rip.

Oh yeah yeah. I have traction control completely off and it's just getting sideways something else. That's really really cool, so the whole auto tune feature um and the fact that you can run mixes of ethanol. That is phenomenal, so you know coming from the same generation if you were working on a mercedes or an audi or something - and you did modification big modifications.

You'd have to find a tuner and pay a lot of money to get your car either tuned by mail or on a dyno many many hundreds of dollars, and if you change something you got to do the whole thing over again usually or get an update with This with this auto tune feature because it has that wideband o2. It can correct for modifications, so you can do whatever you want. You can put a bigger turbo on here, a single turbo. You can do hybrid turbos, you can run different mixes of ethanol and it's going to tune for that.

It doesn't actually have an ethanol sensor from the factory, but it reads the ignition timing. It knows when it's knocking and if you have a higher ethanol content, you're gon na have a higher octane fuel, so it's not gon na knock as much so it can adjust for all of that. It's just it's just so cool. I just can't say enough about this very inexpensive platform and you guys that already have the n54 or maybe guys that have newer cars, where this stuff is a little bit more common.

You know what i'm talking about, but for everybody else. That watches me for my mercedes content, my ls content and stuff - i'm geeking out about this stuff because it is so affordable. So you can go and find these jb4s for, like 150 bucks, i bought the little mhd dongle that you plug into your uh obd2 thing. Uh for like 60 bucks, and then you can pick and choose if you just want the back end flash tunes uh, you know you pay for that.

It's just you know for a few hundred dollars. You have a really really fast car and then the mods are all pretty easy on these two. We have the larger, intercooler and charge pipe um. I did the downpipes, which only take like four hours yeah and you get this, so i also have the bigger fuel pump, so i can run more ethanol um, so i'm probably over an e50 mix right now, but anyway, this is like a tuner's dream.

It's like a bolt-on affair, you're not needing to dig into the engine. The n54 is actually really really stout and strong. It can handle a lot. I think guys are pushing like six 650 wheel with a completely stock engine on a car that you can buy for like five or six grand so anyway, i'm a big fan boy.

Now of this whole platform. I know it's can be unreliable and whatnot, but they all can be unreliable. At least with this. You don't have to spend a ton of money to modify it and you can just beat the ever living hell out of it all the time.

And yes, it will probably break at some point, but not because it has too much power. So all right guys that'll do it for this video. I wanted to end it here to show you that, yes, i still have the v12 engine project going on, but no, i don't really have any parts to put it back together i mean i do have some parts fcp has sent a lot of stuff. I got a lot of little parts.

I got some big parts too vrp sent out the new turbochargers um, but i need the cylinder, heads and they're still out getting ported and cnc machined and all that kind of stuff and everything gets bolted to the cylinder head. So there's really not a whole lot. I can do with this engine right now, but don't worry. I have been very busy behind the scenes and soon i'm gon na have the biggest announcement yet to the channel coming it's gon na be pretty awesome.

It's just a big game changer for me, so if you guys have been around for a while if you've been following me for now three or four years that i've been on youtube, you're gon na understand why this is so important to me. So anyway, stick around for a big announcement. Follow me on instagram and on facebook at legitstreetcars.um, and if you like, this video hit the thumbs up button share the video subscribe if you're new, that's it. This is the end of the video.

So, most importantly, have an awesome day i'll catch all of you in the next video.
