Could be from your canister or one or both of the hoses coming off of it. I had all of the above on mine. Easy, but as always, expensive repair. You can get by until you're able to have it repaired by adding ATF. BE SURE TO USE THE PROPER FLUID, NOT POWER STEERING FLUID, BUT ATF (Dexron III, I believe) Check your owners manual.

Be careful, even with DEXRON, or any ATF. To be most safe until you repair it, use the recommended Pentosin CHF 11, or 7 if your manual recommends it. Always be wary of substitute fluids, our cars are bred to run on the OEM and even things "close to it" can do harm to seals, hoses and the like and then you are looking at a much more expensive repair. It is more expensive, but cheaper than a full blown repair if the seals or other parts are negatively affected.

If it says "ATF fluid only" on the filler cap, that's what goes in there, unless you have self levelling suspension.

Correct crewdog,
I apologize for assuming the car automatically had self-levelling system. If it does, it will say either ZF on the cap, or list which Pentosin is needed.

So.....you had the hoses repaired at the end of January and now in April, the hoses are leaking again....is that a correct assessment.

The power steering hoses on these cars are literally BMW's 'achilles heel'. Either your first mech did not know what he was doing, or something in your driving habits is affecting the hoses. I had a similar experience though: Car began leaking and I took it in to the dealer for replacement under warranty. Several months later, I was back at the dealer again for replacement (leaking again). Typically what happens is: The mechanic replaces one hose, and then the other hose starts leaking. Best to replace all hoses at the same time.

Good on you. Stock is not necessarily bad. You can cosmetically face lift it to look like the '01...change lenses front and read, paint the skirts, debadge the rear, buy M pars, drop the nose to give it more rake, black out the windows. Think outside the box, let your mind roll on.

Good luck.

The job is a DIY if you have the time, money, tools, and inclination....but it is messy. Look at www.e38.org for a write up. Check around the various sites, such as autohausaz, bavauto, oembimmerparts, or as a last resort, buy from a dealer if you are in a hurry.

Buy the best hoses you can afford....the stock ones fail repeatedly, and if you replace one, replace all.

I have a quicc question about these power steering hoses what brand do you guys suggest is a better quality? And also, are the two hoses different, if so, which hose am I looking at because the hose on the left side (standing in front of the open-hooded car) of my power steering resovoir is the one leaking?

I just replaced the pressure hose on mine. Took me about an hour total time and the hose cost me $122 . A 19mm wobble socket and a long extension gets the box end pretty easily and the same with a short extension on the pump from under the car. Remove the plastic "skid" shield and it will be stairing you in the face. Don't forget to use new seals which are about .15 cents each.

MBMW is were I got the hose from.

Seattle, WA 98103

Great service and a great price.
Definately use the correct fluid. It states on your cap which one to use and they carry it also. Like stated before its a little more expensive...ok, alot more expensive, but cheaper in the long run!

What are the electrical wires and parts that are screwed to the power steering resevoir called on a 1998 E38? Never really paid attention to it until it started make a fairly fast ticking sound after the car is warmed up. Is that normal?
