DSG, ZF & TCU replacement guides
Separate electronic data transfer, gearbox repair and transmission calibration. Identify the complete application before choosing the work.
Plan the enquiry around the actual job.
State whether the job involves a complete replacement gearbox, mechatronic assembly or electronic controller. Send both labels, gearbox identification and the specialist’s findings. The compatibility and required memories vary between generations.
Cloning preserves supported data for a suitable replacement. Tuning changes supported behaviour on an existing suitable transmission. Hydraulic and mechanical failures remain separate, and commissioning may require coding, basic settings or adaptation by the installer.
