I'd just push it into a lake or something and claim that it was stolen..im with you, it's retarded to shell out that kind of money to fix a motor and turbo... Anyone here have mechanical insurance? I have that with Geico, they'll cover all the moving parts of my car and i only pay extra 40 bucks a year.

I have 20k and we can confidently say there are 1,000+ procede users out there with various mileage on their cars, i have seen a number (sorry didn't count how many) post about 30 and 40k+ cars with procede, no issues.

Most insurance policies have exclusions for modifications unless you specifically insure for them, in which they probably wouldn't approve an engine modification in the first place.

yeah that kinda what I was thinking. I know you can warranty cosmetic mods, but when tuning an engine i think all insurance companies would stay away from that

Can you post the DME print out with the customer/dealer info blocked out. I believe you, just want to see what they look like. Thanks |

I don't have his printout with me now, and probably wouldn't post his personal read outs publicly anyways. However, here is part of a 11 page printout report on another modified 335i. You can see how much stuff in monitored from manifold pressure sensor, throttle motor, light bulbs, exhaust valve, etc, etc. It tells which ones will trigger a CEL etc. Most of this stuff probably wouldn't show up on a generic code reader. Modified cars with CELs start showing more peculiarities in their fault signatures that BMW is becoming pretty interested in investigating. Remember, readouts are uploaded and BMW can immediately analyze stuff from across the country. Pretty interesting stuff?

I think the 335i will be fine for some fun drag runs every once in a while, and everyday driving with mild boost increases. I still believe Dinan researched quite extensively what the little turbos will handle in regards to safe boost levels. I don't think running the 335i on a track with sustained high boost levels is a smart idea. The M3 is definitely the better solution for running a road course on a warmer day, etc. At the end of the year, I may be getting an 09 M3 to replace my 335i sedan. I just don't look forward to getting 12mpg, etc. I think the 335i is perfect with 10-12psi. But who knows exactly what the longterm ramifactions are of specific boost levels. But the higher the boost, the more load there is on your turbo bearings, etc. I think running 15psi+ boost on these little turbos is asking for trouble. The increased temperatures and shaft speeds will kill the turbos, its just a matter of time. Hopefully those that have, or know of failures can post to keep the N54 community informed on this very important subject.

This thread has just 100% justified my decision of going with Dinan. Thank you OP.

FYI: On that vehicle printout above, the low fuel pressure on injector opening is indicative of a failing fuel pump. I used to have long cranking on restart with my car, but that was around 10months ago, and just went away on its own. My car was always strong running so I wasn't concerned. Kind of interested to know if the new fuel pump might make my car slower, but I never got around to doing a before/after Vbox run.

Reason why i didn't buy the M3 is because the 335i has easier/cheaper potential speedwise...but now that this article was brought up, it's going to change my perception dramatically...there are like 5 M3's at each of my dealership i think i'll go check it out soon.

Just as a FYI according to my dealer, this sound is a known issue and BMW is working on a solution.

http://s195.photobucket.com/albums/z...oise_after.flv A solution needs to be worked on for a certain organ in your body. Unless you're talking about something unrelated to the wastegate issue, in which case disregard my comment and substitute the comment that your dealer is ignorant.

Talking about the whining sound in this video (The turbo whine). Mine started doing that long before I even knew what a tune was, dealer was just going to replace the turbos last time it was in the shop but BMW told them to hold off as they think they will have a solution for it soon. |
