Right not realy a car specific question but hopefully someone can help me out. Im getting a MAF error on my car (A4 1.8 T Quattro) and thought before going out and buying a new one I would try and fix the original one. Basicly Ive stumbled at the first hurdle, the maf sensor is bolted in with two bolts that look like a torx pattern but instead of having the 6 points it only has 5. Ive never seen a 5 pointed torx pattern before, anyone know what its called or where I can get one in the UK? Cheers for the help. Pete.
