Has anyone had their vanos changed? On the B58? BMW can’t find any codes when they scan but on my cheap reader I get:

P0012
130713
130715

All point to vanos, I have extended warranty but because they get no codes want to charge £1,000 to strip it and diagnose!! Currently awaiting call from BMW complaints and HQ.

Symptoms are surging/jerking under light acceleration up hills at low rpm and increase in fuel use, no lights on dash and otherwise drives fine.

how did you get on with BMW Dave?
Personally I haven’t had this issue,how many miles has your car covered and have you been changing the oil on a regular basis.
just a thought but have you tried the throttle pedal reset

Mine developed some minor lumpyness at low revs, light loads in the months up to its first spark plug change. Was alright afterwards. Has it been serviced recently?
