Taz x said:IK. said:To be perfectly honest Taz, that is the problem. You're not using it, and thus the oil is draining out of the lifters, giving you that noise.

That depends on who you talk to, basically yes, but try getting BMW to admit it, there was a redesign to improve it which doesnt necessarily imply anything wrong with the old one.
