Thanks for the DIY. I may be doing this myself. I'm curious about the sound it was making...mine has the noise coming from the passenger side when going slow or not moving at all, and only when turn left off of dead straight. No noise when turning right. Sound is like groaning or kind of like a squeegy on slightly wet glass. Fit your profile? Thanks!

The problem is that those who have an AT have to deal with a transmission cooler RIGHT in front of the PS pulley, making the space a little more cramped.

Couple of questions, my car is a manufacture date of 4/00, however i have the LF 20 pump. my questions are:

What years were the LF20 and LF 30 made? and
Which one is the stiffer/sportier pump? (thats the one i want) and
Its is straight fitment or are there modifications?

some of that info is in this thread but not really pointed out and scattered.

Was this DIY with Manual or Automatic Transmission?

Title says it all... I'm thinking about doing this one myself but since I have AT/Steptronic I think I have the big mechanical fan in front blocking the belts. I guess I need to look closer in my engine bay when I get home to see if I can still access the tensioner pulley and take the belt loose from the power steering pump WITHOUT removing the mechanical fan.

That's really the only part of the process that has me nervous whether I can DIY or not.

What we really need is for somebody to find out where we can get the LUK service parts to fix a pump.
It's such a common fault and the parts must be available as 3rd party companies do recondition pumps.

I'm sure lots of enthusiasts would rather spend a few hours on a workbench to save $100's.

bumping this as i have a question. my psp snapped the shaft inside..hence no power steering. i ordered one through my dad's garage at one of our parts dealers...much cheaper price than oem. my problem is that its not the same as what my original looks like. the new one looks like the OP's power steering pump. did they update them or did i get the wrong freaking pump? both are luk. almost had my car back on the road after 3 days....

My psp just popped today and low and behold the diy was on the first page!

I just talked to my local lambo/ferarri/euro garage and they say that they personally will not re-install an LF-20, and only put in LF-30's due to them being a more robust pump. They said that the LF-30 requires a new hose to be used due to the relocation of one of the fittings on the pump itself, makes sense.

If you have any questions about this you can always contact my local guys who are very fluent in bmw at http://www.eurasia.ca. They said the LF-20 and 30 are pretty much the same price.

You can do what you want but I replaced mine with the exact original part for my Feb 2001 manufactured 330. It was the LUK LF-20 BMW part#32416760036 purchased from AboveAllMotorwerks. The LF30 pump I would be afraid might give too much boost as (from my understanding) it's the revised design in response to people having trouble parking b/c of "too much steering effort." At some point they switched back to the less-boosted steering.

More 'robust' or more powerful pump to me sounds more boosted = less steering effort. My pump blew at 100k almost on the button so at this rate I think I'm good until around 200k when I hopefully will have upgraded anyways.

I don't know how true all the pump revision stuff is but my steering was silky smooth before but not too loose and the replacement is precisely the same after the replacement... minus all that pump whining noise!

Rebuilt Luk PS pumps are in catalogs, so someone is willing to rebuild them. However, I couldn't find any available in store or nearby warehouses (thru NAPA & OReilly) a few months ago. So I got a new OEM Luk-20 from Tischer at a discount from full retail price. I found the car drivable without the PS though I bulit up my biceps in parking lot maneuvers.

I can vouch for this Armenian fellow. Just bought one from him, shipped to AUS express post in 3 days for $40US (postage). He refunded the extra money that I paid for postage because it came out to be less.

Got the new pump, used the brackets from the old pump and installed it. WORKS GREAT! + Great deal! Man it's nice having power steering again!
(The old pump 'pully shaft' just snapped in half, fell out of the pump when I finally got the pump out.)

I didn't have to remove the cap, I used the lower hex bolt on the tensioner to loosen the belt. Did you get yours done?

My car is also making the rumbling noise when turning and I do notice less assist in steering. I opened the reservoir up and the fluid was low. I simply fill the reservoir back up to the max with the appriopriate ATF and it drove fine on my ride to work. However, the problem re-occurred when I drove back home. I check the fluid level and it was still the same.

My question is, could I fix it by properly flushing the fluid? Or is it definately a power steering pump failure?

Thanks.

In my case the noise turned out to be from dirt/sand that had gotten into the bearing at the top of the strut. I diagnosed it by jacking up the front and having my son turn the wheel while I listened for the source (engine off). By doing a partial strut removal, I was able to remove the bearing assy, clean and lubricate it. Used a DIY for strut replacement on this site (or it might have been on the M site). Hope this helps.

I'm doing a pump replacment as I've been driving the last week with no power steering, fine when you are moving but ugh! I'm doing control arm bushings too while I'm at it and have the car in the air.

My Ride: 03 330ci
2003 330Ci Power Steering Pump

Just fitted a replacement PS pump on my 03 330Ci following the advice, contributions & recommendations from members on this thread. I was quoted $1400 from "you know who" just for the pump itself !! Then there was labour on top. I would not have got any change out of $2000 .........Then I managed to source a good used pump from a BMW wrecker for $350.

Pretty straightforward to fit as previously advised.

In my case I removed my viscous fan (non electric) and its shroud to gain access to the belt tensioner release which employs a T50 torx fitting as previously discussed. You really need to remove the fan & shroud to give yourself room to work on the removal & refitment of the "serpentine" engine belt. Following an earlier tip I drew a diagram of the belt routing to make refitment easier.

I agree with a previous poster re undoing the fan hub nut, I used a long handled 32 mm spanner & gave it a few sharp hits clockwise with a 2 lb steel mallet.

After jacking the car & removing the large under engine access panel, dropping the pump from the bottom was straight forward after undoing the 3 securing bolts, then rack pressure & reservoir supply hoses & draining off the old fluid. No need to drop the sway bar or disconnect anything else at all. Just remember to undo the PS pump pulley bolts before removing the engine belt. Once the belt is de tensioned & slipped off the tensioner, the pump pulley slides off to the front of the car.

The new pump did take some time to kick in after starting the engine, (air in the system) I just put in full R/H lock, topped reservoir, then full L/H lock the other way & re-topped until it came good. Prior to this, after connecting the rubber fluid supply line to the inlet side of the pump, I waited until fluid was draining from the steel pressure pipe connection before doing up the nut.

All good now & the wife is over the moon with the dollars saved thanks to you blokes !!!!!!!!

So far with help from this forum & its members I have manged to:

Fit new batteries to my keys

Re program keys

Replace SRS occupant sensor from passenger seat

Resolve last stage resistor problem

Resolve park assist problem

Keep up the good work guys !!!!!!!!!!!!!!!!!!!!!!!

I can't tell you how helpful your DIY instruction were for me and my 2001 325i. Had the old pump out and the new one replaced in roughly three hours, very easy thanks to you, Chronic2112. Thank you!
