2010, replaced all 6 at 35k miles this year under warranty (free).

[titium]

95k km late 09 model. 3 injectors replaced by previous owner prior to 80k. other 3 are index 7 and I suspect atleast one is starting to go bad - odd fuel trims on cold start and post cat 02 sensor codes being thrown.

for the high milage guys do you run injector cleaner?

I run 2 rounds of techron back to back every 10-15k miles.

My car is 2009 with index 7 injectors. I had one injector that went bad on cylinder 3. I found when I did a spark plug change at 65k

This past weekend I had several miss fires. I took the car into the dealer and they are going to replace all my injectors. The dealer is going to cover the cost of this under BMW's extended warranty

04/2007 build - original injectors and fuel pump. 23,500 miles. Had long cranks a couple times when the car was brand new but they went away a month into ownership and never came back. Since there was a long waiting line on fuel pumps I didn't rush in to have it replaced, and glad I didn't. Flawless ever since. Only real issue with the car in 9+ years was a leaking valve cover gasket and that is so common with BMWs, that it's really expected maintenance and not an issue. Been tuned since 1st few months of ownership but don't push the car much, mostly cruise when I get the chance.

06/09 build. I purchased the car in 2012 on CPO with 36k miles on it. I now have 109k miles on the car and have never replaced and repaired any of the injectors. I've been running ESS Tuning's Stage 2 tune for approximately 50k of the miles I've owned the car.

[nitehawk]

Summarized the original post with all the feedback so far.
Definitely something to be said about the all the early 2007 models with index 0/1 injectors and no issues...

[FEDE/E92]

07 FBO 125k No injector issue so far...knock on wood

[Gizmo 335i]

2/07 build date E92. Original injectors. 88k miles stage 2 Cobb/MHD tuned since 80k. Run a bottle of techron every 3rd tank. Vast majority of fill ups were with Shell V 93 octane fwiw.

[TrAcK TRaP]

3/07 here with original injectors index 01 at 81K miles. Car is tuned since 30K still running strong with stock turbos @20.4 psi injectors 01's are magical I am telling you..

[Ty@TCS]

07 335i w/ 120k miles and Index 1 injectors here. Originals from what can tell

[posite]

07 with index 1, Low miles at 40k but that brings its own set of challenges

How did you get your injectors covered I have a 2009 built in July of 09 and they said not covered
