Power Steering Fluid Leak on a 2003 X5 4.6is

Granted also this required draining all the previous fluid.

Cap was probably replaced along with the reservior with a non-BMW part at some time in it life.

Cap with a Pentosin CHF label

Good tip. Mine has the ATF stamp as well. And the reservoir always has fluid seeping on the outside. I didn't realize it's possibly because of a failing cap seal.

Is there a cap seal you can purchase by itself? Or do you have to replace the entire reservoir?

Btw, congrats on getting to that 7000 mark!

Found both on Fcpeuro.

Not there yet, but at least it will be a post on an X5 issue and NOT about Politic.

You may be able to buy the seal from FCP without having to buy the entire cap and reservoir.

Did you replace your entire steering hose for the E53? I have yet to investigate the source of the leak, gets so cold early on I don't feel like crawling under and open the under panels.

Maybe next week when I can bring the truck inside the garage.

I don't even have 1/ 10 of your post counts. LOL

First time I dealt with this leak I thought it would be the seal, too. But the only way it would be the seal, since that reservoir isn't pressurized, is if you over filled it completely to the rim or you have been taking your X5 on some very step angles after nearly filling it to the rim.


I think Upallnight was simply stating that the type of fluid your system requires would be on the cap/reservoir label if it was original. But if there is any chance it has been replaced there is always the possibility the a PO may have purchased a reservoir and lid with the wrong label(s).


Upallnight, please respond so you hit your goal!

Of course you'll have to source the proper hose clamps.

Heck, while I'm here:

4.4 M62
32416758958 Suction hose
32416767138 radiator return line
32416851217 reservoir

On the Fcpeuro site the part numbers for the 4.6is seems to fit these 3 parts instead of the 4.6 you've listed:

32416758958 Suction hose
32416767138 radiator return line
32416851217 reservoir

Do you have a link to the proper hose clamps for these 2 hoses?

I went off a build date of 6/2003 on realoem since yours was an 03.

But you're right. I'm double checking now and that appears off. I always triple check my numbers before I post so I don't look like a moron. I'll correct those. But that is why I always try to include the link to realoem.

I usually have a reserve of different size hose clams that I've bought from the dealer to fit different scenarios. My dealer is good at knowing I don't want those crimp on ones.


My local dealer has a policy of matching prices from another dealer. So I hit up thebmwminipartstore.com/ since they are an online dealer and print off the prices to take to her.

Thank you absolute zero for clarifying. I have these 3 parts in my cart and wanted to get your input before buying. I also have the OE reservoir which is 30 bucks cheaper than the Bmw part.

Hopefully this is all I need. Have you replaced these parts on the m62 engine? Is the space really tight like upallnight said?
