Just wondering if anyone can help shed any light on what may be a little problem.

Come home earlier and the fan stayed on for quite a while and ended up having to take the fuse out for it to stop. Left it for over an hour put the fuse back in and the fan was off - the car got to temperature and the fan cut in and then stayed on again. This hasn't happen before - it usually goes off as soon as the car is turned off.

what year/engine?:rolleyes::doh:
 
If fan is ECU controlled, for some reason it thought it was hot.

If not, it was hot.

Either way, if it was hot, and it's a 1.8, it's probably fecked.
 
sorry for not supplying all info - profile relates to my freelander which was fecked a while ago and is now long gone

this post relates to my father-in-laws 51 discovery td5
 
Don't D2's have a viscous cooling fan, so u either have a retro fitted electric fan or you a talking about the single a/c fan in front of the rad. Which is it?

yep they have a viscous and an aircon fan. If the aircon fanhas come on then the ecu thinks the engine is getting fried.

As stated by Sierraferyi t really needs plugging into a diagnostic puter. It could just be a dodgy temp sensor but needs the codes reading and live data checked to confirm.

This is a latched fault code ie something has occurred in the past which triggered the 'fan demand' - so until it is connected to a Nanocom/hawkEye type device you won't be able to unlatch the demand.

Takes about 20 secs with HawkEye.
