this past sunday I started my car and I had an immediate reduced power code (1/2 engine light), CEL, and rough idle. Let the car sit for 20 minutes, all codes gone, everything was working "normal". But I still had a slightly rough idle @1500-3500 rpms @ cold start-up. I went ahead and set-up a service appointment for Tuesday. Just talked to my SA today, they have replaced all 6 injectors and spark plugs. They are checking the car every morning for rough idle @ cold start-up and no codes thrown so far. They are going to keep my car until tuesday to make sure this fix holds up and they are letting me keep my loaner until then, a 335xDrive coupe. Guess it's not so bad, just hope what they fixed holds up. :cool:

*I go to Center BMW in Sherman Oaks, if anyone is curious...

wanna chip the 335i?

:lol: tempting :devil:

how funny would it be if my loaner's hpfp went out :doh: :confused:

Eh who cares if it holds up or not... you're returning it anyways in a few months... I guess for the next owners sake hope it holds up.

true, but I don't want to spend the last few months of my lease making service appointments and wondering if I'm getting a BMW or enterprise loaner, and for how long....

word :nono:

I have had my fuel pump replaced twice and once again have gotten the reduced power and 1/2 engine light. Car also stutters when accelerating. Dealer has me scheduled to "clean" my injectors.

What did you do to get them to replace all your injectors? I think cleaning mine is a waste of time, especially since my car has never drank anything less than top tier premium. But it's what they want to do.

Sorry to hear of your problem Gene. Another reason to stay away from the N54 motor. I just hope that the twin scroll, single turbo motor in the F10 535 doesn't suffer from the HPFP issue.
