Hi all, I started a thread some time ago about this problem. My experience was in a Touran 1.5 dsg, I rejected the car after testing because of lacklustre performance.
As Mike suggests the dsg box irons out the jerkiness .
Our friend Vinalspin has some technical knowledge, and has suggested, any tweaks VW make to solve jerkiness will effect performance even more.
My suggestion is, don’t touch this engine unless you have thoroughly tested the vehicle. Do not believe the Sales staff if they say it’s fixed. Test the actual version you are ordering.
Regards, wonky
