hi, new to this so forgive me if i cock up.
recently bought a A3 2.0 fsi Se.
had abs module and egr valve changed because lights were flagging up on dash.
now engine mgmt light back on, notice this happens on hot days and that the radiator cooling fan stayed on one evening when i pulled up at home, ran thru diagnostics and it mention cooling fan relay short circuit or something like that, the light went back off but now on again. can anyone shine any light on this before i spend any cash on it, guy i bought from is refusing to fix anymore problems, thanks alot johnny.
