7 Speed DSG Faults | Mechatronic

The 0BH 0BT DQ500 DCT mechatronic unit suffers from various faults which cause the driver to experience symptoms like harsh or incorrect gear changes, or even complete loss of drive.

This semi-automatic dual clutch gearbox relies on the correct function of the mechatronic to regulate clutch operation as well as gear changing. Faulty DSG mechatronic units can result in damage to the gears and reduced service life of the dual clutch pack.
