FAQs » Fuel Caps » AUDI

Why you shouldn't buy and fit a Cheap Diesel Filler Cap to your AUDI

Fitting a cheap fuel cap to your AUDI is not recommended. Because all AUDI filler caps are NOT created equal. Many sold online in the UK are cheap imports from the Far East. Ask yourself how they could sell at half the price you might expect to pay on the High Street or from a specialist online seller like us.

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 specification, you know you are fitting a safe, well-made product to your vehicle.

What payment options do you offer?

We offer all customers a fast, secure and reliable service. You can choose to pay using credit/debit card, PayPal account or Nochex UK. Your order will be dispatched by Royal Mail or courier within 24 hours of payment being received.
