Just getting to grips with my 2001 A4 2.5 Tdi. It has exhibited a huge array of odd faults over the short time I've had it. So far I have replaced all the ABS sensors, the battery, temp sensor, thermostat. Most of my gremlins have gone; all save 2. 1. Fuel guage is erratic 2. Temp gauge either works or doesn't read at all The themostat replacement was necessary as the engine now heats correctly. But the guage it would seem is also faulty. The car has already (by previous owner) been 'clocked' so preservation of the mileage recording isn't too important. Is it possible that this daft act has caused the problems? Can I simply buy a replacement instrument cluster and swap old for new or is there a more involved process? I did my best to search previous posts and have read about possible callibration and encryption issues. What do I need to be concerned about? Also... any ideas what a dealer would charge to do the job would be useful. Might be that it isn't the instrument cluster that is at fault but given the ABS light very occasionally goes on and off by itself I'd say it is on its way out. Perhaps I am overlooking something? Thanks for any advice.
