Try looking for the codes on the ross-tech wiki - It helps to explain them in plain english and give possible causes

hi can anyone give me some advice,i unplugged the mass airflow meter on my s3 and since then i have the engine warning light coming on,i took it to a garage they reset it but an hour later back on again,i took it to audi and all of a sudden they tell me the exhaust gas temp sensors gone and the air flow metre and my brake light switch is causing the esp light to come on,it all sounds a bit suspect as the car was fine before i unplugged the air flow metre cheers

Unplugging your maf will not cause your engine management light to come on, usually the traction control light will come on but go out once it's plugged back in again, it must be a coincidence you egt sensor went at the same time probably causing you em light to come on as for the break light switch they probably found that when thew scanned it with vag com, if all you brake lights are out then this needs fixing, do a search on here, cheap and easy to do. Hope this helps

I've recently done mine, bout 8quid from the stealers. New switch should be green have the part number somewhere if you need it.

EDIT:
Sorry thats for the brake light switch
