I purchased a VAG-COM cable and VCDS software (full Hex Can function) to tweak my car and customers cars in the South West of Sydney. My initial complaints of poor throttle response and hesitant acceleration from stand-still have been mostly resolved. Compared to the soft DSG reset suggested by Umai Naa!! , VCDS adaptation did a much better job with DSG and throttle.
If I didn't have the R36, I would probably think it's a design flaw.
Still, the R36 has still greater part throttle street driving responsiveness which I've come to figure out as being due to the shorter gearing. In the R36 at 100kph, the RPMs are around 2400rpm by memory; the CC at same speed is around 2000rpm. The BWS V6 3.6L engine produces max torque from 2400rpm and up so it's real responsive at that RPM. To get the same responsiveness in the CC, you need to drop a gear.
