E39 Powersteering Pipe + Reservoir Renewal DIY

Hi Guys

So I decided to tackle my leaking powersteering hoses today.

I have been planning it for a while, so I've done research and bought everything up front

I Replaced both hoses from the reservoir and the reservoir itself :

My E39 is a 2000 528i, uses a M52TUB Engine.



Part no's 1 and 14 here : http://www.realoem.com/bmw/showparts.do?...g=32&fg=20



Also make sure you replace both o-rings, part no's 11





There is a copper squash washer on the hex bolt, part no 12, that you cannot buy separately. I had a bunch lying around a luckily had the same size so watch out for this. if you only notice this whilst attempting it, you will end up with a leak if you are unable to renew it.

Reservoir , Part no 1 :



Bmw Part no : 32416851217 , here : http://www.realoem.com/bmw/showparts.do?...g=32&fg=20





Here you can see the filter connected to the reservoir with a torx key



On with it then...

Remove the air box along with the MAF sensor and the 1st intake rubber boot. Leaving the 2nd rubber boot that fits over the throttle body itself. Close the remaining boot with a rug so no dirt or gunk falls down into the throttle body whilst you are working in the engine bay

(I work near a mine so she is very dusty )



After having created some space, I syphoned out as much powersteering oil from the resevoir using a pump I had and a cut up 5L water bottle as a catch pan





After getting as much fluid out as you can, turn the cap back on and undo the 2 bolts holding down the powersteering reservoir holding bracket







Once the reservoir is free, you can undo the clamps at the bottom of the reservoir, one at a time.
Bring your catch pan closer lol! Once the clamp is loose, you can pull of the old hose. Watch out, the remaining fluid in the reservoir will spill out.

As you can see, I had a nasty leak


Same with the next hose

Also try and get as much oil out of the hoses as you can. This will minimise spillage when removing the hoses as the bottom.

Once that's done, you can get to removing the 1st hose completely, by undoing a hex bolt holding the hoses in place

Now when doing this, position your catch pan on the ground at the bottom of the connection your are undoing. more oil will of course spill



Whilst undoing the bolt, the whole black part acts like a clip and pull right off. The pipe also pulls out hassle free



Now you can replace the new pipe along with 2 new o-rings over both pipes at the connection, and tighten the hex bolt again. Remember the washer.

Onto the next pipe. This pipe has a factory clamp you have to cut off in order to get it free. With minimal working space, this will test your patience a bit. Get in there and cut it of. Once that's done, remove the pipe, again watch out for spillage.

Old Pipe still connected
