R56 MCS Coolant Temp Problem - Auto Electrician?

[Eddie_JCW]

In fact scrap that it's in the driver's side footwell
down next to the accelerator pedal by the looks of it

Item A3 is the fuse

Nice one, cheers mate.

If there's nothing coming out the bleed screw that's where I'd start, surely you should be getting coolant coming out, I could be wrong. Sounds like there may be an air lock.

If you unscrew bleed screw ....water should come out

^^^ yeah I'd agree Brian if it doesn't there's definitely an issue ... I know the R53s are hard to bleed and it can take ages to get it right. Last time I did it I just rang the hose pipe into the system and kept filling it until such times that the water had forced any air out of the system.

Good news - sort of. Car got up to temperature nicely this morning! Looks like it is an airlock and I think I know why. When I was accessing the oil filter, I moved the expansion tank out of the way and disconnected the return pipe which lost a little water in the process (don't know why this didn't occur to me before now!!) so I presume this is where the lock has come from as it was fine before. I'm going to do a vacuum fill at the weekend just to make sure it's properly filled.

So now I just need to fined out why my fan isn't coming on and investigate my spotlamp fuse.

Thanks again for your help chaps.

If anyone has any ideas on the fan, let me know

It's an insanely high temp the fan kicks in at, I'm sure it's over 100 degrees C which the R56 rarely reaches unless it's a warm day, sat idling for ages or it's been a hard drive it's rare I hear my fan running and I can't resist using all my power all the time

In heavy town traffic I regularly reach over 100 C and all I ever get is the reduced power message at which point I pull over, switch off and start again. I've never heard the fan until the other day and now nothing again.
