VW Window Motor Part Numbers Explained: 6Y1, 6Y2, 6Q and 7H References

VAG window motor numbers can look similar even when the applications differ. The BVS catalogue provides useful examples of why the complete reference should be treated as the key identifier.

6Y1959801 BVS lists this as a front-right or driver-side motor for specified Polo 9N and selected T5 applications.

6Y1959802 BVS lists this as a front-left or passenger-side Polo 9N and 9N3 motor.

6Y1959801A BVS also lists a related 6Y1959801A product, showing why suffixes should be checked rather than assumed interchangeable.

6Q1959802A BVS lists this reference for a Polo 9N front-left passenger-door application.

7H2959801 and 7H2959802 BVS lists these as T5 window motor references.

The electric window system is made up of the switch, wiring, motor, regulator and glass mechanism. A fault in any one of these areas can produce similar symptoms, so the most reliable repair starts with diagnosis rather than immediately replacing a part. Listen to the window, check the basic electrical supply, inspect accessible wiring and consider the condition of the regulator before ordering a motor.

BVS currently lists 6Y1959801 as a genuine Volkswagen electric window regulator motor. The live BVS listing identifies VW Polo 9N and selected Volkswagen Transporter T5 applications and specifies the listed unit as front right or driver side. BVS also advises matching the exact part number and confirming the vehicle application before ordering.

The full original number should be photographed before the old unit is removed. Record every character, including suffixes. Then compare the number with the replacement, followed by the connector, mounting points, drive arrangement and door position. A similar looking VAG motor is not automatically interchangeable.

A window that is completely silent may have an electrical, switch, wiring or motor problem. A motor that can be heard running while the glass remains still points more strongly toward the regulator or mechanical drive. Slow movement can be caused by motor wear, but it can also be caused by tight guides, a damaged regulator, contamination or poor alignment.

When a used OEM motor is considered, testing and condition are important. BVS describes its 6Y1959801 listing as used, genuine Volkswagen and fully tested. That can make a tested original component an attractive repair option on an older vehicle, provided the exact number and application agree.

Installation varies by vehicle. Normally the door trim must be removed, the glass secured, the electrical connector disconnected and the motor fixings removed. The regulator should be inspected while access is available. After installation, test several full cycles before refitting the trim and check for smooth movement, abnormal noise, glass tilt or incomplete travel.

How to use the catalogue correctly Start with the original number. Use the vehicle model as a secondary check. Then confirm side, connector and application. This approach is much safer than selecting a motor from a photograph because it looks similar.

For trade buyers Keeping the original part number with the vehicle registration or VIN makes repeated sourcing much faster and reduces returns.
