Hi all, having a problem with my girlfriend 2.0TDI 140 A3, the fans are staying on when the engine is running. last time it did this i think i replaced a coolant sensor on the right hand side of the engine near the air box? i know i didnt have to replace the fans or anything. iv had a look through as many old threads as i can find but still cant find the part No for the sensor. Is anyone able to point me in the right direction of it?
