R50 power steering pump replacement

Hi,
My power steering pump failed a few days ago, luckily just reversing off the drive. Strangely it's working fine today but I'm not risking driving it until it's fixed.

My question is will an r56 pump fit my R50?

eBay lists one that fits 50/53/56. A friend works at bmw and said it was fixed after 2007 because it was a common problem. He also said the R56 pump is different to the R50 and won't fit. While I'm taking his advice I'm here to double double check.

Any advice welcome, thanks

Jayne.

No an r50 pump is totally different.

This is an example of a r50, r52, r53 pump.

Hi Jayne76,

I know it was almost 2 years ago, but I hope you're still around here.
I had an unusual experience today, similar to yours. I reversed my Mini on approx. 50 yard long, and the power steering suddenly failed in a strange way: it felt like if it was doing it's job into the opposite direction, making the steering almost impossible (I'm not _that_ weak, and I had cars without power steering). Stopping and starting the engine solved the problem ( a'la Windows '95 ). Perhaps the reversing confused the software via a supposedly one-way sensor?
Did you found the cause of your problem, or simply replaced the pump?

it has is a circuit board inside the pump that over heats or oil has leaked from the pressure side and makes it intermittent at first,, i promise you it will keep doing it and one day you could be driving along and need to turn car and it wont not a good feeling,, the only correct and safe way is replace the pump,, BBA REMEN do a pup with life time warranty on it for £180 believe me its the safest option, link below,

What usually kills them is graphite dust, which is obviously a great conductor, from the brushes wearing done and getting onto the circuit board inside. By far the most common cause. Another common symptom of failure is that they continue to run after you've turned the car off. Same reason - graphite dust. And that flattens the battery in two shakes. Not heard of them overheating. BBA Reman in Rochester, Kent are the people as Mike says. I've taken PSPs there as they are near me. 100% know what they are doing.
