Hi,
I'm new to the forum, but hope someone can help. My A6 (2.6 V6) had the throttle position sensor fail. I replaced it and now get the fault code 0522-Engine Coolant Temperature Sensor. I replaced the ECT and got the same code. I checked all wiring to the ECT and reset and the same fault code resulted. I thought possibly I got a faulty ECT so swapped it for another one, cleared the faults, drove it for a couple of kilometers...same fault code 0522. Hmmm.

Any one else have this problem or know what to check? I am trying to exhaust all possibilities before reprogramming the computer.

Thanks.
