Product Details

Motorad MGC930T is engineered as a tethered fuel tank cap for select Audi A3, Audi S3, Volkswagen Beetle, Volkswagen Golf, Volkswagen GTI, and Volkswagen Jetta models. This fuel cap is intended for vehicles that require a black, non-locking cap with a tether and a 1.88 in threaded neck diameter.

This part number, MGC930T, is also referenced in OE-style replacement listings for the same application.

This part cross-references Genuine 1K0201550F for the same application.

What It Helps Address

• Fuel odor caused by a worn or leaking cap seal
• Evaporative emissions faults related to poor cap sealing
• Check engine light concerns tied to fuel vapor leakage
• Cap loss or misplacement on tethered-fuel-cap vehicles
• Improper fitment when the original cap uses a 1.88 in neck diameter

Installation Notes and Tips

Verify the filler neck diameter, tether style, and cap depth before installation. Confirm the vehicle’s model year and fuel cap configuration against the listed fitment, since some Audi and Volkswagen applications vary by production date and filler neck design. Make sure the cap seats fully and turns to a secure stop after installation. The MGC930T is a direct replacement fuel tank cap for the listed applications and should be checked for proper sealing after installation.
