Fuel station - fuel is coming out

Hello!

I'm from Slovenia and I recently started driving an A4 TDI (11/01, 74 kW), and I'm having a strange problem.

Fuel is leaking from the gas cap and it's clearly visible on the fender and bumper. I initially thought I might have overfilled the tank, but even after refueling, it was only half full. Then, after a short highway drive at approximately 150-160 km/h, it was the same again.

I think there might be pressure building up in the storage tank, or perhaps a valve is blocked.

Has anyone perhaps had a similar experience?

Nelo.

I suspect the seal in your fuel tank cap is simply defective. --> Replace the fuel tank cap and that should fix it.
