Right here we go, i brought a atmospheric dump valve for my a3 1.8t and it ran like a complete Piece of POO. any way after messing around for ages decided to call up bailey motorsport and ask for some help!! ( i had brought a twin piston dump valve) When i told bailey they laughed down the phone at me a told me that the A3 will not run with a dump valve fitted in place of the recirc valve, so they quoted me £140 FOR A DUMP VALVE THAT FITS IN TO THE COLD SIDE OF THE INTERCOOLER PIPE. and it works prefectly with no problems this is all thanks to a guy tha helped me out previously on a different thread. TRUST ME IT WORKS PERFECTLY
CALL BAILEY MOTORSPORT!!!!
