Hi, Had the engine management light come on about 6 weeks ago on my a3 2.0 tdi s line dsg, mechanic ran a scan, intake manifold flap not opening/shutting correctly, replaced intake manifold flap (£360) Cardiff Audi, light still on !! Replaced fuse (f8) as it had blown, only knowing that from the forum so got my guy out to run another scan & reset hoping that it would stay off this time. Nope scan was saying mass air flow sensor/ signal too low !!! Replaced the maf myself and the bugger is still on, got my mechanic out again hoping that it only needed resetting. While he was there the light was out, he said that a gearbox solanoid error was the only 1 showing up on his scan, told me not to worry about it and the engine management light shouldn't come back on !!! He left, as soon as i started my car the next time the light was on again & is staying on !!! Wtf doing my head in, don't think I'm going to use the same mechanic again but need to get it sorted !!! Any ideas ????
