I agree that Autologic for the N42 engines has always had the 'adjustment' facility for variable valve lift. This N46 used DME_meV 9_2 which did not, on the Autologic system, have that adjustment. I spoke to Autologic who then incorporated this adjustment into the MEV9_2 software (and made it available to all in release BMW101 onwards).

All arguments aside, i adjusted the lift up a little with the new software and the problem was 'cured' (i use that term very liberally and not as a difinative indication of a permanent fix).

As for Andrews comments, the dealer tool may or may not have this functionality, but as i dont use the dealer tool i find the tone of your response unhelpful and uneccesary (unlike the majority who took the time to offer genuine advice). To assume i dont have the "product knowledge" just because i dont choose to use the dealer tool is incorrect at best.

By extension, the next time to try to code folding mirrors-on-lock on an 2010 M3 and cant do it with your "dealer tool" that would give me the right to insinuate that you "lack product knowledge and experience and dont know any better" just beacuse i can do this with my aftermarket tool!

Wish i hadnt bothered to post the results now.....
