tried that, air con and heating off altogether, as i found that it turns the air con on when set to demist, but no difference. I have tried with the temp sensor disconnected, no change, checked all connections again today, disconnected each one and reconnected to make sure they are all plugged in ok. The only thing that makes a difference is to unplug the fans lol.

I have searched the web, but only results i get is for fans not coming on at all. Wouldn't be so bad, but Abi (the wife) didnt notice it until i pointed it out, and is now going on about it lol.

just a daft thought but make sure you have all the codes radio / alarm e.t.c. but when we had trouble sometimes with modules we used to disconect the battery for a few minutes then re connect . ued to work with some marques . but was never fan related ...

Ive had this a few time in the past, if the ECU for the engine sees an open curcuit or incorrect resistance from the fan switch, it will put the fan on all the time, its a default mode of the ECU to protect the engine, check the sensor wiring, is it plugged in? hope this helps

Tried this one today, hod the battery disconnected for about half an hour, as some of the cables needed re-routing as they were annoying me, but unfortunately no change. Got told off for not re setting the clock though  :doh:

Unfortunately i have a nasty feeling that this is the problem. I re checked all the plugs yesterday. As far as i can tell everything is connected, and i unplugged and re connected them all again to check. There is a resistor on the fan shroud, that i have seen mention off a few times on the web. So i guess i may need to check this.

I am glad i usually stick to my old non electric 300TDI, At least if i miss something on there, i usually have the bolts or big bits of metal to show it  :huh:

Now then.....

...as its your wifes car are you sure it was not happening before the clutch job especially as you said she diddnt notice? if so....

It could simply be the sensor is faulty, maybe it reads 16c by defualt. Try testing its resistance, dead short often means its duff, but you need to find out the correct value beofre testing as it may be volts based etc. Alternativley if the sensor is not too expensive and not in a place where its a pig to change, just replace it, there is no point spending too many hours researching/testing when a new part will rule it out in a moment.

It could be a faulty wire, try remking (a few times) all the connections you broke as it could be a bit of corrosion side a connector some movement may re establish the connection. Also the wire in the connector could have been strained, so try wiggling the wires around and looking at the output to see if it jumps/etc.

Possibly if it is clutch change related, you have not conencted or got a bad earth possibly if you greased bolts etc. Check any earth straps you made and ensure The have continutiy.

My very brief experiance of DTC codes is that they are not 100% relaible in ruling things out due to how the ECU "sees/interprets" various signals etc.

Let me knoe how you get. on
