What it does
This mechatronic unit controls the DSG’s shifting logic, clutch pressure, and hydraulic functions, working with internal sensors and solenoids to enable smooth automatic gear changes.

Common fault codes
Typical diagnostic trouble codes associated with failing or faulty DQ200 mechatronics like the 0AM 325 065 S include:

• P17BF / 06079 / 06300 / 06293 – Hydraulic pump/pressure build‑up restrictions

• P0841 – Transmission fluid pressure sensor implausible signal

• P1604 / P0562 – Internal control module or system voltage errors

• U0101 – Lost communication with TCM

• P173A–P173D / P177F / P189C / P1895 – Selector, pressure or sensor faults
  These codes point to internal electrical or hydraulic problems within the transmission control unit.
