Thats it! Thats why I paid so much! I remember I bought the thermostat with it which was £40! So the pump was around £80! :P

Wow IIRC I paid alot than £80 quid for my BMW water pump it was more like £200. A very easy DIY takes about an 2hours using standard tools apart from the special hexagon key to loosen the belt otherwise a piece of piss to do.

Ordered an exchange BMW one.

I've got shipwrights disease now though:

Should I change temp sensor, thermostat and rad hoses at the same time, or a I just being paranoid?

Already got a new radiator and header tank ready to fit.

The stat could be done at the same time I guess. Did you call the dealer to see if it was a metal impeller pump?

Yeah I might just get the stat and have done with it.

I went to the dealer, they didn't know if it was plastic or metal, just that it had been redesigned due to problems, and was now an exchange only item with surcharge.

Oh right. My dealer implied it was fitted to some cars from factory...

I'll find out for sure when I swap it.

Either way, the old rad, pump & tank are going on EBay - they do work after all.

I just bought a water pump from the dealer for my M57 330d touring.

It was £105 once I return the old one.

However it was definitely a plastic impellor on the one I received.
