Mein Auto: 335i
Turbos replaced in 335i

So I have a 08 335i sprt sedan with 64k miles. A few months ago I was having issues with the wastegates and the dealer found a bad vacuum line that fixed it after bringing my car in 2 different times. The car was fine then I noticed a squeaking noise coming from the turbos a second after I turned off my car. Took it in and they replaced the turbos. Took it back cause of it running and idling round they replaced all injectors and plugs. Now my car seems to be fine but when all that was going on I was talking with BMW NA and was telling them about the issues. They recently emailed me back saying they would give me $7500 towards a new bmw and it would get to trade in or sell my current one. I really love my car but am afraid of anything that might go wrong when my extended warranty is up next September. Should I keep my car as it is fine now or look into getting a newer one with less miles and more warranty left?

Tough call. You have new turbos and injectors, an extended warranty on HPFP and whatever else BMWNA has extended so a lot of the more costly stuff is covered. So you could have years of trouble free ownership. But on the other hand, a lemon is a lemon, they do exist, so BMWNA making the offer they did might be a good way out from under a constant money pit. So again, a tough call. But if it were me, take the offer and run.

Turbos replaced in 335i

So I came into the dealer today and my I found a 09 335i with 34k CPO. My sales guy is telling me to stay away from the n54 and go with the n55. He said there is a reason they change to the n55 motor, being that the n54 had so many issues. I love the n54 motor and my car can I get more opinions about what you think the sales guy is saying.

If you looking into buying a new car i highly recommend that you do your homework on the selection of cars you are viewing and make sure they have good reliability. You should get a new ride if your Turbos blew out at 64,000 miles.

N55 engine is used because it is CHEAPER than the N54. Dual turbo vs dual scroll single turbo.
If you like the car keep the car. You have replaced most of the expensive items on your engine already and still have extended BMW warranty on the turbos and HPFP.
Keeping it for a few more years isn't going to drive your value down that is for sure so why not keep it.
If you are serious about selling the car and don't wish to sell to a private party try Carmax. They tend to pay a lot more than your dealer will...

It isnt CHEAPER, they used a different technology. The turbo in the N55 is still pretty strong. You can still tune the N55 as you can with the N54. If you dont feel comfortable in that car, they are giving you a nice chunk of money towards a new car. There are alot of 2011's coming off lease you may be able to get a good deal on.

When BMW NA offered the $7,500 credit on a new BMW I suspect they were referring to a brand new BMW and not a new to you BMW. You might want to check with them to see if they'd give you the credit on a used BMW.

Turbos replaced in 335i

Thanks for the feedback. So my turbos didn't blow there was a squeaky noise I heard coming from the turbos which I guess some rod in the turbo was bad and they replaced them. I didn't get any codes and the car still ran fine it was just that noise I heard and that's why I took it in. I have heard a lot of other horror stories on here and other forums about 335s and I feel my issues aren't nearly as bad as others. I do think I still have a good car I am not sure if I want to go with the n55.

Aside from the engine and transmission, which everyone has the same potential for going bad, I would definitely keep it now with new turbos installed at 64K! I believe that is a $7500.00 repair??? They only have a couple moving parts, the critical one being the turbo blades from what I understand. For all the threads I have read, I can't remember many engine failure issues on these and even the transmissions seem to be really solid. All common issues have been bad HPFPs, Waterpumps, Coils, and Injectors which they have covered and improved. Very impressed with the engineering on this car. That said, if I got another one, would definitely be an M3 with no sealed turbo system to fret over.
