This is very frustrating. I had this problem a few months back after my car sat for about 3 months. it's been about two months now and when I turned it on this happened:
I have no idea here. No CEL (
)
Without a CEL the dealer will obviously not replace the HPFP or the injectors (I believe someone previously mentioned those as potential issues). I'm debating replacing the HPFP on my own dime and if it fixes the problem ask BMW to reimburse me (a pretty ballsy strategy if I do say so myself). Could it be a dirty MAF sensor? I'm not even sure our car has one.
When I had this issue before, it went away after about an hour of driving. I'm really not interested in waiting an hour for this problem to go away. Today, I had a scary incident parking the car where I was pulling into a spot and the car randomly revved lurching me forward.
