OVERVIEW
Genuine VW/Audi Gasoline Fuel Tank Cap with Retaining Tether
5Q0-201-550-L is the genuine fuel tank cap used on the matched gasoline filler necks below. The cap closes the filler opening using the original sealing arrangement and includes a retaining tether to keep it attached to the vehicle during refueling.
This listing supplies one fuel cap with retaining tether. The fuel filler neck, filler flap, hinge and surrounding body components are separate. Match the complete original cap number and the vehicle’s filler neck before ordering.
Technical details
- OEM number: 5Q0-201-550-L / 5Q0201550L.
- Application: Original gasoline fuel filler installations assigned this exact cap.
- Retaining feature: Attached tether as shown in the archive photograph.
- Closure instruction: The pictured cap specifies tightening until one click.
- Quantity: One tethered cap per purchased unit.
- Application control: Fuel type, original filler neck, sealing arrangement and factory part assignment.
The cap is part of the fuel filler’s sealing system. Its sealing surface and closure mechanism must match the filler neck. A visually similar cap may use a different seal, neck engagement or tether attachment. Verify the original assignment rather than selecting a cap solely by model name or handle shape.
Common reasons to replace
Replacement may be needed when the cap is missing, its housing or handle is damaged, the seal is worn or cracked, the closure no longer engages correctly, or the tether has broken. A damaged or poorly seated cap can contribute to a fuel vapor leak. An incorrect replacement cap can also prevent the filler neck from sealing as intended.
A check-engine light or an evaporative-emissions fault does not by itself prove that the cap has failed. Inspect the cap, seal and filler neck, then follow the diagnostic procedure for the recorded fault. Vapor lines, valves, wiring and other fuel-system components can cause similar symptoms and require their own diagnosis.
Fitment
The table lists confirmed gasoline applications for this exact L-revision cap. Match the factory assignment and installed filler neck, particularly where a vehicle has build-date revisions. Diesel and hybrid configurations require separate cap verification.

Installation and service guidance
Follow the vehicle owner’s manual for opening the fuel filler and removing the cap. Keep the cap and sealing surfaces clean, and inspect the filler neck for damage or contamination. Attach the retaining tether at its original mounting point without twisting it or trapping it in the filler flap.
Fit the cap squarely to the correct filler neck and close it according to the instruction on the cap and the vehicle owner’s manual. The archive cap states to tighten until one click. Confirm that the cap is seated and the tether allows normal operation of the filler flap.
If an evaporative-system fault prompted replacement, complete the required diagnostic checks after installation. A warning light may need the specified drive cycle or diagnostic procedure before the system reports its result. This cap does not repair a damaged filler neck, leaking vapor line or failed evaporative-control valve.
