I've replaced motor and transmission mounts in my S3, to alleviate the thumping taking off in 1st gear. It's better, but still there. I've removed the driveshaft, thinking the bearing carrier is shot, but the rubber doesn't seem much different than a new one. The U-joints seem fine, there is no play and the action is smooth. This car sat unused for nearly 10 years before I got it. Is it possible that the guibo took a set and is the cause of this problem?
