my 57 plate audi s4 cab wont start
it drives fine for a while and then your get in it to come home and it wont start,everything
normal turns over just wont start. si there could be 15 mins could be an hour then try it
starts fine and is ok for a while again
Could be egr valve sticking open at times causing it not to start.
Or maybe even pcv valve sticking open.
