If valvetronic is related to VANOS and I think it is, you don't want it in your car. Just take a look at the E46 M3 forums to learn about the $4 to $5K VANOS failures that are popping up all over the place. I have an '04 M3 with 29K miles and already got a VANOS failure code. These do not show up as early as the HPFP issues, but will also be a cause for worries...
