Hi zedders, I've recently been hearing the cooling fan rev up & down on cold start up which it never used to do 
After a bit of forum searching & a trip to my local Indy to hook up to his diagnostic machine, it was confirmed my n52 electronic water pump was fubard (almost)
Not unexpected as my car is approaching 90k & these things don't last forever-these magnesium engines don't take kindly to massive overheating so I stopped using the car & ordered the pump in :roll: (oe supplier)
Off to my Indy this morning, undertray off & the highly trained tech (my nephew) removed the old pump while I went about changing the engine oil & filter
Expensive paper weight...
It's so much easier when it's above your head
It's very important to use new fixing bolts when the new one goes on, I got 3 new ones from bmw for £6.11
The diagnostic machine tells you what to do
Job finished & pleased to have my zed back in rude health again
Regards
