I've just bought a 1999 S3 and the onboard computer display is completely blank. I've had a search on google and as a result tried switching it back on using the reset switch on the stalk and I've also tried removing and replacing both the fuses listed as instrument cluster in the handbook to see if this would help. Unfortunately to no avail. Is it common for these to die completely? Is there anything else I can check?
There is a boost/oil temp/oil pressure gauge on the dash that the previous owner fitted which lights up with the dash lights. Could something maybe have been accidentally unplugged or similar when this was fitted? I don't really want to go pulling the dash to bits if these things generally just die anyway.
