VW 0AM / 0CW / DQ200 Common Fault Codes and Repair Measures

Please note that this guide is provided as a general reference and in no way constitutes an official recommendation. We constantly update this list to cover more Volkswagen & Audi error codes.

Some error codes may appear multiple times in this table.

Common issues when disassembling and reassembling the transmission:

1. The Shift Forks and their Push Robs (Actuators) must be in “Neutral” positions.
2. Push Robs (Actuators) has two versions with different lengths: 1st generation (part number 0AM325091E, Mechatronic part number 0AM325025D) is 101mm, 2nd generation (part number 0AM325091F) is 99mm.
