Mmmm..turbo BBQ

rideelement247 · 03-08-2008, 02:01 PM

So I brought the car in for the cylinder 3 misfire and they also pulled cylinder 1 misfire codes as well. They pulled out the sparkplugs and the bottom part looked like the car was running super rich and the top part looked like it was running super lean.

Guess what else my SA tells me? My front turbo is overheating to the extreme. He said when you open the hood you could almost get burned from just the fumes

. The car isn't throwing any codes and runs just about normal when driven after the spark plugs had been replaced, but both my SA and the tech who drove the car @ different times after the spark plug replacement noticed the ar smells like it is burning. My SA wants to get me a new turbo but can't validate it with PUMA until a code is thrown and is trying to get the code to be thrown today and tomorrow so he can order a new turbo. Also, for an unknown reason, he tells me my car is dumping fuel onto cylinder 1 which is most likely the cause for the turbo overheating. He has no idea what is wrong as of this point and has no where to go without a code being thrown. He even said the car could work itself out and be running fine but recommended I leave the car for the weekend so that he can try and get the code to appear.

Not necessarily another one BLOWN. Not blown yet, and my wastegate sounded NOTHING like AU335's. Had that rattling noise (like the car warming up and maybe a little flutter noise on the 3K rev), but hopefully it was just the sparkplugs and my poor car can come home. The tech working on my car thought I had been running NOS on it he said the sparkplugs looked so bad.

But my SA does believe my front turbo is on its way out the door

At least you have a great SA to work with..that's a big plus! Good luck, bro.

Yea he's straight. Supercharged M3 with NOS

, my car must be a civic to him lol.

Hmmm... looks like I might have to get under my car and check things out. The other night I heard a "flutter" sound when revving the car in neutral and the RPMs were dropping back down. To my ears it sounded like an exhaust leak, but I'll get under the car and check now to make sure.

At least its good to hear that you have a cool SA to work with. That's a pretty rare thing to find.

It's weird in my car, hardly sounds like anything is wrong at all. The flutter is quieter than the exhaust rattle during start up(that, or my wastegate has a seizure when I press START

).

rideelement247 · 03-08-2008, 03:59 PM

Oh BTW, there is a TSB out on the turbos on the 335i, not by prod. date or anything, just a shitty part in general. So says my SA.

Yep. I guess these cars are designed for the old folks, and then they would die just past warranty, where BMW could reel the sucker back in. I guess it's all marketing, shaft the consumer after warranty and he is bound to buy from us again. I guess BMW just made the links too weak to last longer than 5000 miles

Good luck OP. I'm at 16k now with no problems (knock on wood). These failures are getting a bit too common.

Yeah, too common, going to take it easy on the car. Less 0-1000000 for me.

Great more doomsday threads.

Not sure about your SA though talking about how "he can feel it under the hood" in reference to your turbo "cooking".

Just stating what was said to me. I didn't take a doomsday approach, more of a

50 thou for what? attitude. He just says the car smells like it is burning when they drive it and noticed the car is dumping fuel into cylinder 1 and the turbo is overheating due to that. He says it is cooking though. Maybe he put the car on a lift after spirited driving? I don't know. I am just relaying what I am told.

Yea wasn't accusing you of anything, just saying your SA if giving you some sketchy info.

judec · 03-08-2008, 07:24 PM

the turbo overheats when the engine is running lean. the unburnt fuel is supposed to cool the turbo down, so I guess the overheated turbo is on the lean side of your engine, not on the rich side. I understand that turbo needs to be replaced, hopefully just the turbo, but I dont see the reason of the failure. why are some cylinders in your engine running lean? I dont see how could a faulty turbo cause that, if it would not supply enough air, the cylinders would run rich, than the ECU is supposed to intercept and cut the fuel down... I dont understand.

Wish U good luck.

Sounds like a fuel delivery problem no? HPFP?

Well the tech who replaced the spark plugs said the bottom half of the plug showed signs of the engine running rich, then the top half showed signs of the engine running lean

. The misfires were for cylinders 1 and 3 which correspond to the front turbo. I wonder why cylinder 2 wasn't going bad as well. Oh there was also a code for super-knock in there as well

.

It is an 08 and supposedly has the HPFP. My SA said the HPFP wasn't throwing any codes.

someone should compile a list of production dates, symptom, and tunes. We may be able to narrow down the problem.
