help me to diagnose

Well check Engine light up yesterday.
2011 e90 323i N52n 106k
Problem, not every time but, sometime at idle the rpm start flickering for 1k to 1.5 or below.
then go so low and make the engine stop.

Ignition coil? Sparkplugs? Others ?


Thx

+1, clean vanos solenoids. Contamination affects camshaft timing and will cause the symptoms you describe

Had same problem, try cleaning vanos solenoids first. If that doesn't help replace them. Easy fix.
