Hi all, First post, loving the forum so far. Ive had a search but nothing seems to match my current problem. My Avant doesn't register a temperature at all. Its always stayed on 0. I have asked at Audi and its either a sensor or the dash apparently. I think its the sensor as there are a few other niggles with the car. Its reluctant to start sometimes when really cold, its really lumpy at idle (quite violent sometimes) and its using loads of fuel. Typical MPG is down to 24 average on a mixed run. Does this all sound like a sensor or is something more sinister afoot. Its had a new fuel rail.injectors just before i bought it. Been back to the dealer it came from to be scanned on a computer but nothing came up. Any ideas? Cheers. Nathan.
