Hi Everyone just joined so my apologies if this is a silly question, I recently purchased a 2010 A5 2.0 TFSI convertible and I had a POO16 code come up, I replaced both the camshaft and crankshaft sensors and now it turns over but will not start! any suggestions would be greatly appreciated, also a strange thing happened whilst I was replacing the crankshaft sensor, all the windows went down ?
