Fuel Cap Cords for BMW, Audi, Mercedes & Volkswagen
Every driver has done it — opened the fuel flap, unscrewed the cap, set it on top of the car, and driven away without it. A fuel cap cord (also called a fuel cap tether or lanyard) is a simple, inexpensive fix that attaches the cap to the fuel flap hinge so it stays secure while you refuel. Our OEM-spec replacement cords restore the factory safety feature on BMW, Audi, Mercedes-Benz, and Volkswagen vehicles where the original cord has snapped or worn out.
OEM-Grade Materials for a Factory-Perfect Fit
Our fuel cap cords are made from UV-resistant polyurethane or nylon — the same materials used in factory production. They clip directly into the original attachment points on your fuel flap and cap with no drilling or modification. Installation takes under five minutes and the result is indistinguishable from the factory original.
Small Part, Real Benefit
Beyond preventing a lost cap, a secured fuel cap ensures the cap is always within reach when re-sealing — which matters on modern vehicles where an improperly sealed fuel cap can trigger an evaporative emissions warning light. Pair with other practical cabin and exterior accessories from our interior car parts collection and exterior car accessories.
Frequently Asked Questions
Will this fit my specific BMW or Audi model?
Each fuel cap cord product page lists the specific model and year compatibility. Our cords are designed to match OEM attachment points — no modification is required for the listed vehicles.
Can I replace just the cord, or do I need a whole new fuel cap?
In most cases, the cord alone is sufficient. Our replacement cords attach to your existing fuel cap using the factory retaining clip, so there is no need to replace the cap itself unless it is damaged.
My fuel cap warning light came on — will a new cord fix it?
A loose or missing fuel cap is one of the most common causes of the evaporative emissions (EVAP) warning light. Replacing the cord keeps the cap attached and properly sealed, which typically resolves this warning after a few drive cycles.
