My friends (08) R56 has been acting up and finally stopped working while running. He had it towed and according to him the code meant 1,2&4 misfire. Since he's out of warranty and being cautious before going to the stealers, I adviced him to start inspection from plugs, to wires, to coil so he can eliminate those first. Does anybody had any similar experience? Thank for any input. Happy New Year To All!

 

I'd tell him the same thing. Check plugs, wires, fuses. When he pulls the plugs, look at the tips. See if there is any heavy build up or anything out of the ordinary. That's weird that you would get so many misfires at once. How many miles are on the car?

 

About 28k only.

 

i saw the same codes but as pending codes once, likely caused by rough stumbling on a cold start, which is likely the HPFP.

cleared the pending and haven't seen it since, but car still stumbles for first 10 seconds while driving as though its not getting enough fuel/constant fuel supply while throttle is depressed.
