Did you figure it out? Same thing happening with mine and I'm considering just bringing it into a shop but also wondering if they would even be able to figure it out |
I haven't. I've replaced the whole system and still no luck. I'm down to 3 last possibilities. 1-Bad DME. 2-Bad bank 1 cat. 3-clogged secondary air raceway. Valencia BMW couldn't figure anything out either. So fucking frustrating!
