Hi, does anyone know where the switch/temp sender  for the electric fan is, the fan is now on from cold.

And type/part no ?

Is it only on for the first few minutes max?

If so, then thats common and mine is doing it.  The ECU will have logged a thermostat circuit error, I've been told its common and a new thermostat is required which will fix the issue.

My thoughts are that 'ill get around to it' but for now ill let my car sound like a london bus for the first 2-3 minutes of cold start as it heats up the the correct level.

I caused replacement of the whole unit albeit a guy I know sorted issues by swapping out the stat.

make sure your ac is off as well. ac turns the fan on.

The fan is on all  the time and aircon off. I have located the sender switch, now trying to find part No, cheers for the replies.

Iirc when I looked into this there wasn't a seperate part listing for the switch.........Only the aux fan could be bought complete & not cheap.

There was a site where an owner fixed theirs not sure if it wa switch or motor - I believe this was on  an E39 540i....but not a 5 min fix.
