Right ive got an 04 A3 tdi 140 Lovely car! battery was flat as i left it stood for a month or two and wouldnt hold charge, it is 9+yrs old so splashed out on a new BOSCH S3 (there are two but i went for the more expensive one from ECP) Started her up, first time perfect! then ping abs fault, red steering wheel no power steering GREAT! abs fault went away when i drove it around the block, but still no PS Checked the fuse, fine what am i missing out on? is there a reset thing i can do? is it because when i changed the battery it lost all the previous settings? (radio was in safe mode?) not sure if it was related but i turned all the airbags off as a friend had all the airbags deploy just by changing the battery haha!
