2004 A4 cooling fans run at full speed for 9 minutes when the car is just started cold. Then run normally? or at least turn off. Dealer replaced tempsender (059919501A) faults they found P1260, P2181- found ECT faulty and replaced. I assume thats the temp sender? Anyhow, took car back once when it still was happening and they didn't see it. Still has problem, so thought I would give them more info so I don't waste my time again. Thanks
