2005 Audi A6 3.2L /85 000km/ My cooling fans stay ON at all times and doesn't matter if the engine is cold or warm.As soon as you start the car they go ON high speed/both fans/ and stop in about 1min after you turn off tthe ignition. No MIL ON , no DTC stored. Replaced the Fan Control Module still the same. Fuses and relays OK. Temperature sensor also OK.On cold start engine warms up as usual and normal to 90 C .
Anybody with similar issue? Help needed?
similar issue on our 2008 A6 C6. Everything seems to work fine so I have not bothered with it (plenty of other things, like suspension upgrade, which need my time and attention). However, if I knew the fix I would probably go for it.
Was the ECM the problem, or did you have to replace the ECM anyway and this took care of the problem? Was it a simple flash upgrade or an actual replacment?
ECM replacement seems like more $ than I want to get into. Thanks for any advice!
