My 2007 audi a8 Quattro instrument (small) panel between rev counter and speedo has suddenly gone blank. Cant reset computer 1 or two which default to OFF. Am I missing something obvious? Just noticed that the dash/all instrument lights are at full brightness and I cannot dim them.
No change as yet with the problem. It would appear as though there is no power to the driver information module/screen. I've check all the relevant fuses and they are ok. The screen suddenly went off and the only associated problem is with the instrument panel dimmer which now fails to work and instrument lights are at full brightness all the time. I believe that there is a light sensor which is part of the driver display module so the fact that the instrument light control has failed may be to do with that. Does the driver display module receive its power via a relay? All other systems on the car work ok including the MMI. Cant think of anything else to try other than probably having to pay a fortune to AUDI to diagnose the fault and fix it. Guess they will come up with replacing the instrument panel as I would imagine that the driver display module can't be changed on its own. .I would appreciate any comments and or ideas you might have regarding this problem. Thanks
