Also, I was concerned that the "hicups" I was feeling sometimes when i shifted from 1-2 or 2-3 were from either the CDV or just my bad manual driving abilities but my friend was saying when he drove my car that it may be the turbos kicking in. I know this isn't a "Turbo" thread, but it may be beneficial if someone could explain this so people would know what aspects of their driving (smoothness of shifts) is due to their manual driving abilities, and what can be attributed to other factors.
Do they fit a CDV on the 335i? I ask because I also drove a Z4M Coupe and starting off in that was ghastly - very difficult to pull away smoothly. Later someone told me that it was the CDV and there was a fix for it. I drove a 1 series Coupe as well which I thought shared the same gearbox as the 335, and that gearbox and clutch was a pleasure to use.
