Remanufacture may be possible
| OBDII | VAG | Description |
| P173A | Position sensor 1 for Gear Selector, unlikely signal | |
| P173B | Position sensor 2 for Gear Selector, unlikely signal | |
| P173C | Position sensor 3 for Gear Selector, unlikely signal | |
| P173D | Position sensor 4 for Gear Selector, unlikely signal |
Check the position sensors and the corresponding magnets for contamination by metal particles.
If there is any contamination, check the gearbox thoroughly for mechanical wear/damage. Then clean the sensor and check that the error code is still present. If this is the case, then it is still plausible that the TCU is defective and needs to be remanufactured.
If in doubt, please contact our Customer Service.

The above error codes usually appear after installing the Mechatronic. These error codes indicate that one or more shifting pins are not properly mounted in the forks of the gearbox.
DSG 7 DQ200 (0AM) repair
DSG stands for "Direkt Schalt Getriebe” or Direct Shift Gear. The 7 for the number of gears, the letters DQ for transverse placement of the transmission and 200 for the nominal torque. The control device of this DSG transmission is called "Mechatronic" It is therefore in fact also a self-shifting manual gearbox. The 0AM is a 7-stage version with a transverse transmission with a nominal torque of 200 Nm, equipped with a dry plate coupling. The 0AM is used in various small and mid-range cars of the VAG group: VW Golf IV, VW Polo & Audi A3.
The driver can notice faults with the DSG gearbox when the gear shift indicator in the dashboard flashes, the DSG gearbox no longer shifts and the car shocks when driving away. Moreover, the DSG can spread a burning smell in and around the car.
Common faults and fault codes
Common faults include a short circuit in the gearbox control device and/or a blown fuse, complete electronic failure of the gearbox and internal leakage in the hydraulic block. Various fault codes can also occur on other control devices in the car.
Technicians can observe faults during a test drive or during a workshop inspection of the vehicle. If a short circuit is present in the TCU ("Mechatronic"), a burning smell is observed and communication with the unit is no longer possible.
The problems and defects are often caused by conductive deposits in the gearbox oil. This leads to a short circuit and a burned-out fuse of the "Mechatronic". Cracks in the hydraulic block around the pressure accumulator may be present as well. This is due to the large mass of the accumulator in comparison to the unit.
Remanufacturing process
Before a TCU or other component is submitted, it is important to make a proper diagnosis. This will enable a proper and quick remanufacture to rectify the fault.
