Parts categories
The parts most commonly involved in DSG repair. Not every part is available for every family or generation — availability is confirmed when the part number and transmission are matched.
Mechatronic components
Hydraulic valve body parts, solenoid valves, pressure sensors, hydraulic fluid, sealing gaskets and covers used within the mechatronic unit.
Sensors
Input, output and intermediate speed sensors, hydraulic pressure sensors, temperature sensors and their connector interfaces.
Clutch components
Dry and wet clutch packs, clutch seals, clutch release components and the dual-mass flywheel on applications where it is part of the drivetrain.
Internal gear components
Selector forks and rails, sliding bearings, synchronizer rings and other internal gear components where they are available as service parts.
Seals and gaskets
Mechatronic cover gaskets, hydraulic circuit seals, clutch housing seals and general sealing sets used in transmission service work.
Fluids and service consumables
Gearbox fluid, mechatronic hydraulic fluid, filter elements and fill/drain plugs where they are supplied as service items.
DSG part numbers vary by transmission generation and vehicle variant. Matching on vehicle model and year alone is not reliable — the correct identification is the part number from the existing component together with the DSG family and, where possible, the VIN.
When to replace a part and when to replace the assembly
Individual parts
Where a specific component has failed and is available as a service part, replacing the individual part can be the economical route.
Mechatronic assembly
Where the fault is spread across the hydraulic or electronic assembly, or the unit is not serviceable in place, replacing the assembly is the reliable route.
What we need to match the correct part
- Part number The part number from the existing component is the most reliable identifier.
- DSG family The transmission family the part belongs to, confirmed from the unit or a scan.
- VIN Where possible, the VIN, so the exact generation and variant can be confirmed.
- Fault or symptom What the vehicle does and any fault codes, so the part can be checked against the diagnosis.
Fault codes related to this part
These fault codes are often linked to this part. A stored code alone does not prove that the part has failed — confirm the cause by diagnosis before ordering.

| P0867 | DQ400E | Transmission fluid pressure — low / implausible | Hydraulic pressure |
| P0962 | DQ400E | Pressure control valve 1 — low control current | Valve / solenoid electrical |
| P0966 | DQ400E | Pressure control valve 2 — low control current | Valve / solenoid electrical |
| P172A | DQ400E | Hydraulic pressure — too high | Hydraulic pressure |
| P172B | DQ400E | Hydraulic pressure — too low | Hydraulic pressure |
| P179C | DQ400E | Main pressure valve — electrical malfunction | Valve / solenoid electrical |
| P17BF | DQ400E | Hydraulic pump system overload protection | Hydraulic pressure |
| P189C | DQ400E | Function restriction — insufficient pressure build-up | Hydraulic pressure |

Questions about DSG parts
Are DSG parts interchangeable between families?
No. Hydraulic design, clutch type and electronics differ between families, so parts are listed per family and must be matched to the correct one.
How do I find the correct part number?
Read the part number from the existing component and confirm the DSG family from the transmission label or a diagnostic scan. Send both with a quotation request and we will confirm.
Do you supply the mechatronic assembly as well as parts?
Yes. Replacement mechatronic assemblies are listed on the DSG mechatronics page, and individual parts are listed per family.
Is every part available for every family?
No. Availability varies by family and generation, and is confirmed when the part number and transmission are matched.
Can you supply parts for older DSG generations?
Where the part is available as a service item, yes. Send the part number and vehicle details and we will confirm.
