Hey all, the e34 in the pic below is getting long in the tooth and is away at college with my daughter. Before anything bad happens, I知 looking to get her a e90 facelift 328i with low miles. I値l be replacing the cooling system and do all the regular items (plugs, coils, brakes, etc) before I ship it off to her and recover the e34.
However, I致e seen some good examples of 335s out there too. I have the same twin turbo engine in our X5 and enjoy it, but with her being away, I知 concerned about the turbos giving us problems.
Do the 09-11 335 have a history of turbo problems? Are they relatively easy to replace? What is the usual cost to replace them (I do my own work)
Thanks

Well, plenty of stuff on Google, just looking for opinions. I assume they start failing about 150k miles for mom and pop driven cars?

2009 and early 2010 cars are N54 powered. This engine is the king of tune-ability(its becoming known as the german 2jz), but isnt known for its reliability(there is running joke threads on many 335 forums with pictures of these cars on tow trucks). The N54 is a twin turbo and they typically last about 160k miles before they become problematic(burning oil). Replacing them is a large job, and not for the faint of heart. Expect to spend at least $1000 for reman turbos unless you want to gamble on used units. Theres a pile of other seals, gaskets and bolts you will need to complete the job as well. Lots of people take this opportunity to install upgraded turbos.
late 2010+ are N55 powered. This is a single twin scroll turbo engine. I have little experiance with them but the consensus is they are quite reliable. No where near the same aftermarket tuning support for them though.
Both engines are direct injected and have issues with carbon buildup and injector issues(especially early N54 cars.. not as much issue in the years your looking at)
I Love my N54. I do all my own work as well and it hasnt been too bad. If you want to be able to play with it and get some more power id go N54. IF your just looking for a sporty commuter the N55 might be a better choice.

^ Great synopses, Thanks.
I was told the early turbos had issues, but had no idea what “early” meant. Yep, my X5 has the N55. I’ll look for one of those then.

Injector issues more than turbos issues

Classy. I love the blinkers on that model. So visible.
