On my way to work this morning the red battery light light starting flashing on and off. It soon stopped though and everything appeared to be normal. However, when I parked up there is vibration and a small grumble when I steer (when parking). My thoughts would be the alternator or something. However, I fitted a new battery about 2 weeks ago and tested the alternator at the same time and it read just over 14 volts. Anything I should look out for? It's a 2002 A3 TDI Quattro. Any help would be hugely appreciated!
