Key Product Information
Additional Information
| SYMPTOMS | Typical failure symptoms reported on vehicles fitted with 3D0-820-855-A: slow, noisy, or intermittent operation, a component that moves partway and stops, an audible click without motion, or complete failure that returns after the vehicle sits. Confirm the complaint against the vehicle identification number and option content before ordering. |
| TROUBLESHOOTING | To confirm 3D0-820-855-A is the cause rather than a symptom: confirm supply voltage and ground at the connector while the function is commanded, then check whether the driven mechanism binds by hand before condemning the motor. Compare against a known good side or a reference value wherever one is available. |
| INSTALLATION | Service replacement of 3D0-820-855-A requires the mechanism to be in the correct rest or park position before assembly, and many units need an adaptation or initialization run afterward. Follow the Audi repair manual procedure and torque specifications for the specific model and year. |
| MAINTENANCE | Service upkeep for this motor, pump and actuator (3D0-820-855-A) means keeping the driven mechanism clean and lubricated so the motor is not working against added friction. Consistent service intervals matter more than mileage alone on this system. |
| GENERAL_NOTES | Note for part 3D0-820-855-A: a motor that failed because of a binding mechanism will fail again unless the underlying friction is corrected during the same repair. Genuine Audi parts are built to the original specification, so fit, finish, and function match the factory component. |
| REPLACEMENTS | Associated components for the 3D0-820-855-A repair: mounting hardware, seals, and connector pins are inspected and renewed as needed, and the mechanism is lubricated during reassembly. Replacing wear items together restores the assembly to its original condition. |
