Anyone had a bad experience with the E92 335 N55 engine yet? Or what do you think about the engine. I had 08 335 N54 engine which sucked badly due to the HPFP issues. However, love the car too much and ordered a brand new 2011 335 again with M Package, with the new twin scroll turbo N55 engine. I am signing the paper at Schomp's next week, but hesitate to do it due to the concern with the HPFP. Besides 335, I don't want anything lower. M3 is about the same price, but it's RWD and mileage sucks. So I basically has one option - 335. My SA did said that BMW has the most updated pump for N55 engine, and do not see hfpp to be an issue - yet. What do you all think? Thanks!

Note: BMWNA gives me a deep discount on the new car, so can't really go with Audi or anything else.

I ended up lemoning my 335 back in December because of HPFP and other related issues. Thats when I bought the M! I say go for the M if you can. Sure gas mileage sucks (big time), sure its NA so it looses some power at altitude, sure it is way more expensive, but the driving feel, the sound, they styling, and the 8300RPM makes it all worth it! I didnt think it would be that much of a difference then my 335i but, it is!

I had the MAFS go out on my N55 135i at 420 miles. No other issues.

That's great. Hopefully that's all it is.

care to explain...?

I had a service engine code on my car. I only had 420 miles on the car. I took the car into the dealership. They said the mass air flow sensor need to be replaced. It was the first one they had seen on a 2011 N55. It took 4 days to get the part. When I went to pick my car, they had three other 135's with the same issue.

with various technologies in bmw, it is continue to have all sort of issues. I am not looking forward to see issues coming up on my display. crossing my finger for the new 335i.

I haven't had any issues so far with my 335 n55 engine yet at pushing 8k miles on it now. Has been performing beautifully for me.

Im sick about it. Engine sounds wrong, like it's barely running. knocking or loud ticking from around the pass side of the engine probalbly a lifter. A bad popping or blub blub sound from the charge pipe are. 12 kilometers on the odometer. Idles between 500 and 600 RPM. barely alive. push the clutch and the rpm picks up a little, ya that manual transmission is loading it down. So i take it for a drive. 50km's later the shifter is shaking car is vibrating at idle. Had it hauled to my residence 450 km's from the dealer after delivery. I am sending it back. wish me luck.

^ didn't you message me about the sound? I told you it was normal... :dunno:

[albertabahn]

So the shop foreman agrees that there is an abnormality. Gives me two choices. " we can start taking it apart and hope to find the problem or you can put some miles on it beacuse they need time to adapt".
So I drove it home 500 kilometers from the dealer. Problems persist.
