Now I feel left out, rejected, less than :( And slightly embarrassed :oops:

That would explain the rubber band thingy going round the end of it from the engine.

That's probably why it hadn't failed. It wasn't electric. Less to go wrong. Hehe.
That's probably why your car uses more fuel & produces less power, more parasitic drag on the engine :poke:

Cost seems to vary massively for new water pump installs. Only called one Indy and was quoted £700. Anyone know the rough price to get one changed these days? Any recommendations Manchester / Liverpool area would be great. Thanks all.

Oem pump can be had for £240ish & it's an easy fit, an hours labour?

I'm thinking of doing mine before it breaks. Which brand(s) are best, and where is the best place to buy ?

This thread is getting more positive - last time I posted the fail rate was 1 in 3, now it is more like 1 in 5! So not quite as big a problem as I first thought.

Mind you when mine did die there was no prior warning - everything worked fine until I stopped for fuel, then less than a mile from the garage it just went straight to the red on the temperature gauge and the warning light lit up.

I suppose the nature of how it fails is the aggravation factor - mechanical pumps whine, leak, etc. and give you signs they are failing whereas the electric ones just stop like you've turned them off with a switch. :x

I Just purchased one from ebay for £221 Original PIERBURG pump.

Mine is showing no signs (My local indy said the fans staying on after the car has been shut off is an early sign)

I have been quoted £220 to fit it with a new thermostat and coolant.

I'm driving across Europe next month and its not really something I want to be worrying about as the car has just clicked 70k!

The Pierburg pump should be fine but make sure your Indy uses a genuine BMW stat as in dealer sourced and not an aftermarket 'oem quality' item. These are ECU mapped stats that have about 4 different modes they switch between depending on engine load/driving style etc. and the only one that will behave correctly is a dealer part.

I got the pump for £210 off ebay (find the cheap seller on ebay UK then look through their German listings to save a tenner) then paid £90 to fit it and also repair one of my headlight washers. The mechanic told me he spent more time on the washer than the pump so I paid just under £250 all in to sort mine

As per thread, they do fail without warning. Some have been lucky and got to 100k, others have had them fail circa 60k. In the overall picture, £230-£250 for a pump isn't that bad, and about an hour to fit it. The thermostats are usually fine, normally cracking bodies is their problem.
