Power Steering problems :(

Hi, I bought a 2002 Cooper S at start of Jan. The steering started to get heavy then it would be ok then stopped working altogether. I bought a new power steering pump which this was fitted to the car and i got my car back friday it was making the normal 'mini' noise but i still found it not as light as i hoped, or thought maybe thats how they are? It loosened up nicely and was driving great up till last night.

This morning after heating up outside i jumped in to find it to be like having no power steering again! On the way down the road whilst creeping along in traffc i heard what sounded like something powering up then the power steering worked! then another sound like it was dying and then it went all heavy again

I rang the shop i bought thereplacement pump from who says that id have to pay for another one in full, they would send back one currently on the car to a place who would test it, if it comes back as faulty (which could take 3 weeks) only at that point i would get a refund.

Should the fan spin when the engine is turned over strait away? When new pump fitted fan wasnt spinning when turned over. Called mini garage who said thats fine as temp controlled.

If the fan was faulty originally, could that have been the cause of the 1st pump failing and then blown the new one within 50 miles max? We will be checking to see if there's power there..

There is a power steering pipe under the car which is wet all the way along and seeping. However the fluid is still at max level could this affect the pump? The mini garage say this pipe is £225

The parts are expensive and i am concerned that taking the part off the car to send back to the shop could be hasty as it could come back as non faulty then im liable to pay out for 2 pumps.

Any ideas peeps??

Thanks

Lots of info here which may help:
Power Steering Pump replacement - Forums

MINI HQ in UK are now replacing many early failed ps pumps under 'Goodwill' if you ask at a MINI Dealer, even on older Mini's, although less likely on a 2002 car over 10 years old it would have been worth a try.

Are you using the right fluid? The leaking hoses can reduce the pressure in the lines that the unit needs to do its job properly. Rebuilt pumps are all over the inernet at half dealer prices and hoses can be bought on-line for less too. These units do not use the known power steering fluid. The fan to the pump on an 02 model aslo is fused with the radiator fan. If PWS fan is not working check rad fan too! Radiator fan is by thermal, the PWS fan should be on at all times.

The power steering fan shared the same electrical circuit as the radiator fan until January 2003.

If the power steering fan jammed causing the common fuse to blow, the radiator fan would not operate and the engine would overheat.

It got Mis diagnosed 3 times , thinking it could be the radiator fan . They then said that could've been the reason for my steering being heavier than usual , mines been sorted for weeks now and the steering is back to how it should be . I have to admit mini's are a pain in the arse ! Haha
