OVERVIEW
Genuine VW/Audi Transmission Mount Washer 10.5 × 34 × 4mm
N-903-152-02 is an original Volkswagen Group fastening component that provides the specified seating piece at assigned transmission-mount fastening positions. The confirmed Passat profiles below identify the original gearbox arrangements and fastening locations that specify this exact part. One individual washer is supplied.
Technical details
- OEM number: N-903-152-02 / N90315202.
- Catalog identity: Flat mounting washer.
- Factory specification: 10.5 × 34 × 4mm; 10.5mm internal diameter, 34mm external diameter and 4mm thickness in the factory catalog.
- Profile visible in the original photo: flat annular washer with a central opening.
- Assembly: Assigned transmission-mount securing position, as detailed in the fitment table.
- Supply: One individual component; related bolts, nuts, washers, sleeves and brackets are separate items.
Its internal diameter, outside diameter and thickness are part of the fastening arrangement. A washer with the same central opening but a different thickness or seating area is not automatically equivalent. This is an individual mounting washer rather than a fluid sealing ring.
Common reasons to replace
Common replacement reasons include a distorted, cracked or heavily corroded washer, a damaged seating face, missing hardware, or an incorrect substitute. Inspect the component during transmission removal and refitting, and follow the applicable original instructions where hardware renewal is required. Correct fastening hardware helps restore the intended assembly at the specified mounting point.
Check the complete mounting joint before selecting replacement hardware. Incorrect alignment, damaged mating threads, worn alignment sleeves or a distorted seating surface need their own repair. Replacing this part alone will not correct those conditions. A transmission noise, vibration or starting concern is not sufficient evidence that this particular component has failed; diagnose the complete assembly and identify the affected fastening point.
Installation and service notes
Verify the full OEM number, installed gearbox code and exact original fastening position before purchase. Transmission-mount securing arrangements can vary by gearbox and drivetrain, and parts at adjacent catalog positions can have different specifications. Keep removed hardware organized by position rather than choosing replacements by appearance alone.
Inspect both seating faces and the assigned bolt before assembly. Install the washer at the original catalog position and retain the complete original fastening arrangement. It does not repair damaged mounting surfaces or provide a substitute for a gasket or sealing ring. Follow the applicable service procedure for access, component support, assembly sequence and final tightening. Tightening values and any renewal requirements belong to the complete original joint and must be taken from the vehicle-specific procedure. Do not substitute a generic torque or add an unverified thread treatment.
