Day 11- So BMW called today and advised me that that based on "my recomendation"
they have gone ahead and completed a Walnut blasting to the engine and car seems to be running a lot better. They are keeping him over night to do some more test and I should have him back before the weekend I hope. Since BMW is taking advice from me now, is there anything else they should be looking at or changing?
I don't think coil packs were changed nor MAP sensor clean (as posted above). Let me know what you guys think. Thank again
