I have recently purchased a 2009 Audi A3 TDI 3-door 1.9 diesel and have a problem when refuelling. The nozzle of the garage diesel pump is too large to go fully into the opening of the fuel tank. This means I can only hold it partially in, which causes the diesel to froth and back up in the nozzle causing the pump to cut out. Refuelling takes ages whatever garage I use. I would be grateful for your advice on this problem and whether there is a solution.
