With the A3 it is possible to change the instrument lighting using module 17 Instruments and changing the last digit of the seven digit code to a 4. This gives Needles ON Scales ON. The list of options with the seven digit code are: xxxxx?x 0 = Seatbelt Warning Inactive xxxxxx? 0 = Needles OFF and Scales Off 1 = Needles ON and Scales Off 2 = Needles OFF and Scales ON 3 = Needles ON and Scales ON (Dimming active) 4 = Needles ON and Scales ON Does anyone have access to an A1 and the correct cable to check if this works on the A1. We have taken the car to the dealers and they could not work out how to do it!!. The also contacted Audi UK who said it could not be done, but it seems to use the same J285 module to control the instruments as the A3. Maybe they are right but it would be rather nice to prove them wrong and get it to work.
