R56 radiator fan not running
Discussion
I bought a R56 Cooper S yesterday - it's great, but on examination the radiator fan doesn't appear to run. There's no sign of overheating but without a temperature gauge it's difficult to know what temp the coolant is at. Can't figure out the "secret" menu on the OBC other than it's something to do with adding up the digits in the VIN displayed!
Any thoughts? Temp sensor?
Fuses are ok, and have swapped the I and II relays round.
Assumption is that when the a/c is on, the fan should run - correct?

Not sure at 15 outside, your min AC setting is 16 IIRC, so maybe give it till it gets a bit warmer before condemning it unless someone else knows better.
And before anyone chips in saying "outlet temp should be 6 deg C" yes I know that but I think min temp setting on the AC for cabin temp is 16 deg C.
You could always short the switch out to see if it starts up.
Actually, is the AC coming on?

Well it turns out the fan does run.
I got a bluetooth OBD dongle and Torque app and the temperature sits around 105deg, obviously dropping down into the 90s when moving (from the logging, not reading it whilst driving!)
Parked up, it creeps up but not above 110deg - at which point I turned off the engine and lo and behold the fan was running.
Pretty strong hot coolant smell but perhaps that's just the reality of a small engine bay and a hot engine. Will probably drain and refill the coolant.

Its a 2 stage fan, the first one should come on when the AC is on, the second should come on around 105degs - if you have Mini connected and Nav you can download the app and you can view the temp gauge
Mine doesn't work either, Mini want something like £230, Euros list them, they are around £100.

Definitely doesn't run when the AC is on. Will test out the warranty...Mine doesn't work either, Mini want something like £230, Euros list them, they are around £100.

So they gassed it, and then ungassed it before it ungassed itself 
He said the pressure test was fine but it leaked with the gas in. But apparently it all worked whilst the gas was in. So back next week to investigate!
Did they put dye in so they can trace the source of the leak easier next week?He said the pressure test was fine but it leaked with the gas in. But apparently it all worked whilst the gas was in. So back next week to investigate!
It'll probably be the condenser.
my car runs nicely motorway running fully topped up with oil and coolant but after a while it starts to run hot and i can't hear the fan and then the yellow engine warning light comes on feels like it is running hot, bonnet is too hot to touch for example.
its a 2010 car, recently had new alternator but i've been advised the battery could do with changing - possibly connected? 4000 miles to next service, occassionally the car on ramp light comes on at start up.

So is there a question there?its a 2010 car, recently had new alternator but i've been advised the battery could do with changing - possibly connected? 4000 miles to next service, occassionally the car on ramp light comes on at start up.
