ABS, Handbrake, DSC lights on. Pricey ABS pump replacement?

That's interesting, I fitted winter tyres to it, wonder if that's confusing it. Also had a buckled wheel and broken spring diagnosed when it was in, maybe a pot hole has thrown it out. Had an inspection 2 and brake fluid change in January and they didn't pick up on those then. It's getting to the point now where I feel like I'm telling them how to do their job by suggesting they try different things!
 
Just had a call from BMW and they told me it was the tyres (not being winter anymore but not sure I beleive that explanation!)! The wheel that was buckled had tyre damage to it to the extent they're not prepared to put it back on (once the alloy is fixed). They said the problem was the combination of the failing DSC module, winter tyres and master cylinder. I asked if the tyres were the problem to start with and if the DSC module was acutally OK but they said the initial fault codes specifically pointed at a faulty unit. But then they would say that! Should I ask for the old unit back and get it tested??
 
They are probably talking utter cr@p and just trying to cover themselves. How it could be a problem between all 3 is ridiculous and just shows how lazy they are.

As for the master cylinder, that's even more ridiculous as it's not related to that fault. If that dies, you'll get the normal red brake issue light, and no stopping power :wink:
 
Yeah just spoken to them again and they're not charging me for that. Think it was just the guy behind the service desk reading off a screen and saying whatever. They replaced that before they checked tyres etc hoping it would fix things but it didn't. That particular change was requested by BMW UK!
 
Hello all,

I'm resurrecting this thread to ask a question. I've got the dreaded ABS and DSC warning lights and I've just had the fault codes read confirming its the ABS pump/module. Do you need to drain all the brake fluid to get the pump and module off and then refill/bleed fluid once re-fitted? And if I'm re-fitting the same pump and module after repair, does the car need to be calibrated again or should I be OK. Any help appreciated.

Get the brake pedal pressed down all the way before disconnecting, it will reduce fluid loss. Keep it down until you replace the pump. Yes it will need bleeding with INPA or ISTA-D.

If it's being repaired you probalby will need to calibrate with INPA or ISTA-D as well.

I did it recently and replaced the module as I thought mine was toast so had to code the VIN as well.

I do have a spare ABS module for sale if yours isn't repairable.

Thanks for the info. Thanks for the offer of the module - I'll get back to you if mine is not repairable.

I'm sorry - but I'm a bit lost. What is INPA and ISTA-D?
 
Yes, DSC + ABS lights on is nearly always the pump - actually it's just the brushes on the motor so a pretty simple fix once you have the thing apart (that's the tricky bit). Not sure where you were planning on sending for repair but ECU Testing will charge you around £200. The usual codes are 5DF0 or 5DF1.

INPA and ISTA are scanning software that can be run on a laptop with a cable plugged into the OBD port. Bcables.com do a nice set of software with an easy install (which is by far the worst part!)

Was thinking of sending it to BBA Reman. They quoted a price of between £159 and £189 plus return carriage and VAT. Sure beats £2165.00 I was quoted for a new part from BMW :cry:

Thanks for the explanation of INPA and ISTA. I just checked out the Bcables.com website - that sounds simple enough. £34 for the silver cable and software. How hard can it be? I think I'll give this a go :thumbsup:
 
Think BBA Reman have hit and miss results in here. ECU testing seem more reliable. Just do a quick search on here to satisfy yourself before sending it off.
 
BBAreman have had some pretty horrendous reviews of late. I think you would be a lot better off with ECUtesting.
