Intake cam fault codes
After changing the VCG on my E86 (N52), it idles roughly on startup until I give it a little gas. I get the following codes via Bavarian Technic: 2A82, 2A99 and 2F45. These are all related to the intake cam timing. The VCG change went pretty easily but I am left to wonder why there is no procedure for re-indexing the valvetronic motor. I suspect that these messages, as well as the rough idle, are the result of that worm gear not reindexing correctly to the gear on the cam driveshaft. Every thread that I read about the procedure says that this motor re-indexes itself after a couple of cycles but I have not had that experience as yet.
Is there any other step i can take before having a shop look at it? I have used a 4mm hex to rotate the worm gear shaft in both directions. It doesn't seem to affect this problem. I get no code for a valvetronic motor failure (is there one?). Is it safe to drive to the shop?
TIA
