It happened again tonight at red line in sport mode.
Beside blaming the gas quality, dealer swapped ignition coil from cylinders with problem to ones without. They will know if ignition coil is the culprit if it happens again on other cylinders. If root cause is just simply gas, then I can never drive this car the way I thought it was meant to be again. Plus, closest BP gas station is 22 miles away according to Google map.
I never look at other forum, but I wonder if folks with Audi S7/S8 or Mercedes CLS have this problem. Do folks with F10 M5 or F12/F13 M6 have this problem?
