[bimmertech]

all 655's aren't necessarily bad...just certain production dates.

Sucks, because now I'm afraid to put my downpipes on the car until I'm sure it's resolved.

I am having this same exact issue explained above. Any idea if this is caused by the bad HPFP as well?

My dealer is having a hard time troubleshooting the issue. At first they thought it was the low pressure fuel pump but now they are not sure.

Thanks,
