@36k under recall HPFP and injectors were replaced with index 9 (which I have been told is the worse)
@68k I replaced all with index 12 because first #6, then #4 and then #3 failed.

My original 12/2006 335i had all 6 original index 1s at 107k. Injector 6 totally died at 107k, all the rest were still going strong.
My 10/2008 335i had 3 index-7 and 3 index-9 injectors with 61k on them. No problems or leaking, but I swapped to index-12 for peace of mind.

Mine's a MY2009, I think my build date's in April, but not sure (never really cared). 125k on the odo, 85k tuned. About 430whp depending on the dyno and day.

Change coils and plugs but injectors are untouched since I bought the car.

I will start. My car is an 02/2007 build and was not included in any of the injectors recalls. Still has index-1 injectors that it came with it and still going strong with 84k miles. Been cobb tuned for the last 49k miles.

Am I an exception? I'd like to hear from others if you are still on original injectors without issues:
-your build date
-the index injectors you have
-no of miles
-any pertinent mods

EDIT:

Here's a summary of people still on original injectors, definitely something to be said about the early 2007 models with index 0/1 injectors:

(FYI - Original injector recall was for vehicles built between 04/02/2007 through 10/31/2008)

335Junkie - 10/2006, 151k miles - (must be index 0 based on build date)
Fedorov - 11/2006, 54k miles - index 0
Sgop335 - 12/2006, 93k miles - index 1
Operator Mo - 12/2006, 79.3k miles - (must be index 0 based on build date)
nitehawk - 02/2007, 84k miles - index 1
Boland01 - 03/2007, 82k miles - (must be index 1 based on build date)
Blaster400 - 03/2007, 26k miles - index 1
nikitino25 - 03/2007, 56k miles - (must be index 1 based on build date)
V8bait - 04/2007, 84k miles - index 1?
scottp999 - 04/2007, 23k miles - index 1?
N0Chill 335i - 07/2007
///Mposter - 2007 MY, 53k miles - index 1
DennisPacMo - 2007 MY - index 1
stanlalee - 2007 MY, 157k miles
bizzleb109 - 2007 MY, 131k miles - index 2
1slw335 - 01/2008, 88k miles
veer90 - 02/2009, 90k miles - index 7
nukezero - 05/2009, 124k miles
ttribe - 06/2009, 109k miles

Here's a summary of people that have changed at least some of the injectors:

ritzzzzzwik - 02/2007 - Bank 1 replaced at 110k miles with index 12 (cyl 1&2 were leaking). Bank 2 are original.
Neil07 - 2009 MY - 1 injector replaced at 65k miles - index 7
titium - late 2009 MY - 3 injectors replaced prior to 80k, other 3 are index 7 (one potentially leaking)
idk_alex - 2010 MY - injectors changed at 75k miles
BayMoWe335 - 2010 MY - injectors changed at 35k miles under warranty
125k, index 1.

120k miles E92 June 2007 ..... changed coils and plugs but injectors are untouched. Coils were changed while chasing a limp mode issue which wasn't fixed by that change.
