ABS Pump

That's an interesting thing to know. I'm sure sorting those out would be a fairly straightforward job should mine ever fail.
 
So, I have spoken to my garage and apparently unknown to me the pump had already been repaired (my car has only done 33k miles!). Because of this a quick refurbishment was not possible as the body had been drilled previously by a well known company (this may be common practice?) which rendered it useless. As a result a new body had to be used which pushed the cost of the refurb up to £750. As an aside, my car is a 2007 model and I think because of the low mileage it may have been laid up over the winter, which is what I do. Could this be having an adverse effect on the function of the ABS pump and if so should the car be taken out every month to ensure the parts of the pump are being mobilised?
 
Plausible. The motor is peened onto the aluminium body. Once removed the aluminium body has to be drilled and tapped so the motor can be reattached permanently - but I would not use their services again. As I say ECS charge £220 for a refurb.ly.
 
After removing mine I had to make 2 alloy brackets to re-attach the motor with screws. If your garage replaced the body it should be peened in place - 4 locations where the alloy body is "squashed" down over the steel motor casePump repair.jpg
 
I have been out on a test drive with my garage man and I am satisfied that brakes are ok. You have to beware purchasing second hand pumps as they need to be programmed in to your ECU and apparently this is not an easy thing to do.

So what did they do to cure the spongy brakes then?

Glad they are sorted :thumbsup:
 
Hi
As Rucky stated above send your ABS pump to ECS for a rebuid I had the same problem on my 2007 E92 and now sorted .
Using your own original pump no need to recode replacement unit .

BMW new unit £1800.00 Lol v £200.00 plus fitting !

He demonstrated by using cadence (pumping brake pedal) braking that showed no difference on pressure feedback through the pedal which would suggest that air was still in the system. He explained that I may feel a difference since the pump was replaced as the unit would have slightly different ergonomics to the original. He is a trusted and well known engineer in my locality so I have accepted his judgement.
 
He's talking out of his ar$e. If the ABS pump isn't activated then the brake pedal feel should be exactly the same as not having an ABS pump there. Did you ask if he'd run the ABS purge sequence?

Yep I smell Sh1t :)

@OP How handy with a spanner and a computer are you? If you can get all 4 wheels off the ground and plug a computer in you can do a full bleed yourself. Its quite easy once you get used to the software on the computer as it tells you step by step exactly what to do.

I used this cable, ISTA and a pressure bleeder kit took about 15 - 30 mins and flushed 1l of brake fluid through.

While we are on the subject of brake fluid make sure it is Class 6 fluid suitable for cars with DSC/ESC/ABS as "normal" dot4 is a higher viscosity than the Dot4 Class 6 fluids. The guys on here will recommend a good fluid i just bought the OEM stuff from the parts counter at BMW.
 
Thanks for your info Matty. I will get round to doing what you suggested but it may be a few months so will not update this stream until then. Cheers to everyone who commented!
 
If only they all had a bolted on motor as per Umfaans post.
Most as I say are peened in place - per my earlier photos. Possible errors:

5DF0 DSC - Hydraulic unit pump motor
5DF1 DSC - Hydraulic unit pump motor conector
24048 - Pump motor function faulty
24049 - Pump motor circuit faulty
ABS/DSC Light illuminates occasionally
005DF1 DSC - Hydraulic unit pump motor conector
005DF0 DSC - Hydraulic unit pump motor

No programming is involved if only the Pump or motor is changed/ repaired.
The attached computer is coded to the car so has to be reprogrammed if repaced.

Another vote here for the DIY repair kit ^
Removed the peened motor, replaced the brushes, bled the system myself (with INPA) all for £45ish.
In Newcastle if you ever head south OP. :thumbsup:
 
Hi Allan,
Thanks for your reply!
I hope this string has been useful to other members who experience similar problems with the ABS pump.
Cheers
