"Thank you so much for sending out the fuel cap so quickly. It arrived on Wednesday (in NZ) and I got my Warrant on Thursday. I am so extremely greatful and appreciated of your excellent service. Have a wonderful week. Extremely satisfied customer." (FORD Focus MK1 (1998 to 10/2001) Locking Fuel Cap)

Beware Cheap Imports

Because all fuel caps are NOT created equal, make sure your filler cap is ISO 9001 quality. Many sold online and in the UK are cheap imports from the Far East, hence they sell at half the price you might expect to pay on the High Street or from a specialist online seller like us at The Fuel Cap Company.

But, it's only a diesel cap. Your fuel cap is part of your MOT inspection. It keeps the fuel from spilling out of the tank, should you be involved in an accident. It has to maintain pressure within the fuel tank itself. You wouldn't replace your brakes or steering wheel with a cheap import made from low grade plastics.

Because all our Audi fuel caps are produced in Europe, to ISO 9001:2008 specification you know you are fitting a quality, safe product to your vehicle.

Need a Replacement Audi Fuel Cap?

Many of our customers have found themselves in a similar position. You arrive home only to realise you've left your filler cap on the pump at the local petrol station. So that leaves you needing a replacement cap for your Audi A4 or maybe it's an A6?

Buy your diesel cap from and you get peace-of-mind knowing we only supply ISO 9001:2008 quality caps manufactured in Europe.
