OVERVIEW
Original O-ring for the specified engine cover connection
N-910-084-01 is the Genuine VW/Audi 19.6x3 O-ring assigned to the engine cylinder-block and cover assembly on the confirmed Q7 diesel configuration below. The original seal profile and part specification must match the serviced connection.
An O-ring seals through controlled compression in its assigned groove. The correct nominal diameter, cross-section and factory part number are required; choosing a seal solely by color or approximate appearance can leave the connection incorrectly sealed.
Technical details
- Complete factory number: N-910-084-01.
- Factory specification: 19.6 × 3 factory O-ring designation.
- Design: molded circular elastomer sealing ring.
- Quantity supplied: one individual O-ring.
This listing supplies the individual O-ring. Cover, housing, pipe, mounting hardware and fluids are separate. No material grade or operating-temperature claim is inferred from the archive photo.
Common reasons to replace
- The seal is disturbed when the assigned cover or connection is removed.
- The original O-ring is cut, flattened or hardened.
- Diagnosis identifies leakage at the assigned seal position.
- The original correct O-ring is missing.
Inspect the seal groove and mating component for contamination, scoring and distortion. A replacement O-ring cannot restore a damaged housing or cracked cover. Identify the actual leak source before ordering.
Vehicle fitment
The listed application is the original engine-block/cover seal position with PR 7GA. This does not establish compatibility with every coolant or oil connection on the vehicle.

Installation guidance
Follow the engine-specific cover and seal replacement procedure. Work on a cool engine, control any fluid released by the repair and clean the mating groove without damaging it. Use only the lubricant and assembly method specified for the joint and avoid twisting or pinching the seal.
Refill and bleed any affected system as required by the repair procedure and carry out the specified leak check. Confirm that the cover and all disturbed connections are secured correctly.
