Hi all hope alls ok out there, I've just bought an A4 avant se 2.4 auto estate xreg 2001 (UK) (8d on the vin number I think) from a friend who works at a Range Rover dealership, It has one main fault and thats the engine warning light is on and wont go off.
The machanics at the dealership have done a full check and there is no problem on the system but the light wont reset.
An Audi dealership wants £120 to (check) the problem but the range rover machanics assure me that it's totally fine.
Does anyone know of this problem anywhere else an it be fixed?
Also can the waning light be reset with the Rosstech vcds software and if so which cable do I use?

hope someone out there can help
Best wishes
Chris
