This video shows you how to replace an ABS pump in an E90 BMW 335i. This would be the same for any E90 exc. AWD. I’ll explain how to swap modules. Save money DIY it with a known good used ABS pump.

Any symptoms of the bad ABS pump other than the codes?
I did all that step by step but the abs lights still on . I wonder if I have to recalibrate the module ?
Great video. Quick question, is the one way valve required on the drain tube connected to the caliper bleeder or can I just hook up a tube and put it in a bottle with some brake fluid at the bottom?
Hi! Great Video! Please, can you tell me if it´s necessary bleed/drain the oil before remove the pump or just after the service? I´m very afraid to maker a mess with the brake oil. Thank you so much!
Sorry but just to add, great video! This video confirms how simple this job is. I'll be purchasing a 6 cylinder pump for e90 3 series and swapping the modules over like you did, so I'm hoping I don't need to code anything, as I too have the 335i.
A reconditioned pump that matches my part number is £630 off ebay… I can get a 6 cylinder pump for £200. Only the 4 cylinder pumps are super cheap which is a shame!
If I bleed my brakes old fasion way with 2 people, surely it will be fine? As I don't have Inba and I need to do this as I have the ABS/DSC/Brake error
How do you determine if the problem is with the ABS pump or ABS control module?
very good video, going to try it in a weeks time, can i just ask you a couple of questions, one do you top up the brake fluid each time you drain a side, if yes do you use the same fluid that came out of your car and secondly where do you get the software from? thanks
Great video, well explained.
Sent my unit to be refurbished for £240 including VAT and has solved the issue. Taken off myself, refitted myself using this video and all went very well. Unit can be a tad tricky to take out and place back in due to the small enclosure.
Did not need to recalibrate the unit, however power-bleeding the unit following installation seemed to drain battery significantly and as a result it brought about 5/6 new and insignificant error codes, plus the car on a lift image on the dash. ran the car a couple days and all seemed to be back to normal. Quick delete using DIV57 and all good.
My recommendation would be to reduce the level of fluid within reservoir to below the level of the abs unit, then when disconnecting the rigid pipe lines minimal fluid should leak out. I learned the hard way!
Thanks again, great video.
did the swap today and so far its working properly.. thanks for the video. got the pump off ebay for $130
Great video, thanks for posting.
where did you get your one man bleeder kit? thanks
Hey there thanks for making this video. There are a few dozen part numbers for the ABS pump and they all look different. Are you sure I can swap out the pump with any one from an e90? Can you give me the part number you used?
Aveman1, how do u know if your module is fine? Why did u need to recalibrate your dsc module?? Thanks!
Aveman1, great thorough video. Where can I get the INPA software from?
+Aveman1 I do have one question still. I took my car to an indy shop afterwards to have the brake fluid flushed. They used the pressure bleed technique. I told them that I had replaced the dsc pump, so they bled the dsc pump in addition to bleeding all 4 four brakes. Does that make sense? I did not actually see how they did this but I think they open the brake lines at the pump to bleed it….
Aveman1, I was interested in doing this exact repair as I suspect the same discrepancy. Would you be able to say if I can any e90 DSC pump with another pump of e90, e92, 93 excluding AWD? Both exact same part number have to match or can we use different P/N? Is there an interchangeable part number list?
I'd like to start by saying….great video!
I've a 325 CI (e93) with same fault codes as yours. Can you confirm that all I need to do is:
1. Order new ABS pump (off eBay so comes with module)
2. Remove old pump
3. Replace module of new pump with old module from my vehicle and fit pump back to car.
4. Clear codes
Im no expert mechanic, just do a little buying/selling/fixing here and there. So I have Delphi system and WOW (haynes manual online) only!
Do I need to bleed my brakes? And can this be done manually or do I have to use INPA??
Thanks!
Aveman1 thanks for posting, it helps alot! One question:
-Are all E9X ABS pumps/motors the same across all the E9X models (non-Xi)? The part numbers that I can find online are of the entire assembly including the control unit, so not sure how I can check for part number of just the hydraulic pump and motor. Please clarify, I have a 2007 E92 335i.
Thanks
Did you reduce the pressure in the brake lines before you started to remove the ABS pump etc?
Great video. When I did mine I was too pissed that Bosch built such a piece of trash pump. I bought the whole assembly from BMW of Minn for 970 bucks. I replaced my pump and ABS module but swapped my electrical module. I then decided to fix the pump and sure enough the brushes were gummed up. Bosch never accounted for graphite material build up in the holders. Also removing the DC electrical motor once the tabs are dremeled off take some force because the motor magnets hold the the motor rotor to the housing quite well. I cut access slots in the electrical motor can to release inner tabs on the motor outer can to the bottom of the Bosch base. Once loose sure enough both brushes were gummed up but one was not making full contact on the slip ring thus the rpms for the motor could not be achieved causing the code.
It was not that difficult to remove the motor can to access the motor internals and I did not break the internal tabs that hold the motor to the base (this is where the magnets hold the base to the motor housing well). Once reassembled I peened the aluminum housing to the motor base close to what the original connection was and used high strength epoxy to provide a 2nd level of security.
At the time no one would reveal that other Bosch BMW ABS units would work and I didn't wish to take a change since the car would be down if I was wrong. If I had to do this over again I would either buy a used unit for cheap or just pull the motor and repair it.
Excellent video and should help many BMW drivers to fix what Bosch screwed up. My confidence in Bosch is waning after rebuilding my alternator and finding Chinese bearings inside.
Again a great contribution to helping DIY. FYI the dealerships are charging some poor owners up to 3K for this repair…
Great video. I have the same problem. Where you buy new abd/dsc controller(with pump) ? Thanks
Hey man great video! I never knew the BMWs could auto power bleed the brakes. I need to do it on mine now, what setup do you have and do I have to buy IMPA anywhere? I want it to work exactly like yours did. Thanks again!
