My tiguan 2.0TDi 2009 cooling fan won't turn off. I have disconnected battery in desperation
Hello and Welcome..

My name is ***** ***** Im happy to help / advise..

Im afraid I don't have enough vehicle info from you to ID fuses etc...but that said, these are not normally fused.

The fault is 9 times out of ten, the Fan Control Module - that module does as it says, switches the fan off and on when needed - but when they go faulty - they can operate all the time - or not at all... yours appears then to be the former.

Most any good local garage can sort this for you -- They will check the relay first etc -and for any wiring shorts / faults - but again, replace the module as needed / found... using a smaller type garage would be a lot cheaper than using a dealer.

You have done the right thing so far by undoing the battery - otherwise it would have flattened it - You can use it meantime though / drive it to a garage - it wont do any harm as its running all the time - which is better than not coming on when, it will keep the engine cool...

So thats the way forward on this one now...

Im very pleased to have helped you - Do let me know if you need anything more --
