Hi I have an Aud a6 Sline tdi 2.0 on turning the key
it says ignition on and aloud buzzing noise sounds
which doesn't stop when turning again it sounds
like it's trying to start but fails to do so
Most Commons cause of Audi's buzzing are 1. Turn signal switch failing. 2. the "flasher itself" unplug it for a sound check. 3. loose screws/ bolts(vibrations) under the dash. NOT, your vehicles issue If its just when ignition is in ON position. Regards
Thanks but the car won't start though
Check the battery 12.6 volts? have it load tested OR if its 60 months old replace it. NEXT, check all connections clean ,tight, not corroded? Ground cables case a lot of anomaly's in starter circuits!. This is the best you can do, unless you know how to use a multimeter. The fuel pressure PSI.. needs to be checked as part of the general diagnostic. Have it read for codes, even if the check engine light is NOT on the computer will have stored information and codes. Discount auto stores will read codes for no fee. write them down.
Ok thanks a lot
