Hi, New to the forum, so apologies if I have done this incorrectly!! Just bought an A4 2.0tfsi (55 plate) drove it round all day yesterday and started fine every time (even after 4 hours sitting in cold). Went to start it first thing this morning and it just turns over without firing. I can hear the fuel pump priming when the key is turned to the first position. Any ideas as to what the fault could be, strange that it was fine yesterday and no warnings or running rough!! Any help appreciated, as you can imagine pretty jarred off at the moment.
