I just this done. Not sure if they used repair kit or not. Total bill for me was £100. Total bill without warranty was going to be £1600. It was 26AW's? I think, but that included reprogramming a new DSC module

From what I've read I need to get to the fault codes behind the warnings to know the extent of the issue. What would you guys recommend - take to a local BMW indie (anyone recommend a good one in Berkshire), or some other route? My dealer would probably hit me with a £120 diagnostic charge just to look at the codes.
If you have a a cable and INPA you can get the codes. If you have 5DF0/5DF1 you are probably in for an expensive repair.
Where are you based? Maybe someone or myself can help?

Thanks djgandy. I don't have the gear to get the codes so have been searching for local BMW independent specialists (recommended) to do the diagnosis. I have also contacted my dealer, from whom I purchased the car from new, with a view to them checking the fault codes. If it turns out to be worst case, then I would expect significant goodwill from BMW - the car has been with me from day 1 and has always been serviced 'on time' by BMW dealers. Time will tell of course.

I live over by Newbury.

Apologies for digging up this thread, but as I now have the same faults, I wondered if anyone else that has previously posted here might be able to comment.

Did any of you have the symptom where the ABS pump kicks in every time you turn the steering wheel beyond 1/8 of a turn (left or right) and you are braking? I can feel it through the pedal. It does it at any speed above 15mph. Braking with the wheel straight does not trigger it!

No. And I haven't heard of this before. It sounds like your Abs pump is being triggered by the steering angle. Have you had the codes read yet?

I haven't had a chance with the codes yet. By chance do you know if the BMwhat/Carly app will pull those codes?

Yes I would imagine so. The app reads the modules present in the car and the codes in the modules. I think if you send the log file to the app authors they will provide a diagnosis free of charge.

If heard similar things mentioned on here a few times relating the worn/damaged wheel speed sensors or reluctors. Maybe not exactly the same, but similar.

The ABS computer is recieveing incorrect data from one of the wheels which it interprets as a skid or similar, and thus takes action trying to fix it.

I have just this morning ordered the Carly App and the dongle so I am hoping I can diagnose myself. I'll have a play with the coding of the comfort settings whilst I'm there.

If I have an issue though I might take you up on your offer - thank you! I'm not too far from Southampton either.

hi folks,

just got a georgeous 335d autovogue unfortunatley it has the lights on the dash relavant to this thread.

i have the 2 fault codes that confirm the pump and module are at fault, ill be hopefully sending the pump and module for reconditioning this week.

the parts are going to ecu testing and its going to cost me £195 (lifetime gurantee) + removal + refit and the cost of a brake bleed session.

during my research into this matter i came across the this rather usefull video confirming everything that i have read on this forum and others. I hope new comers to the thread looking for answeres will find it usefull.



job should be complete within 10 days ill report back when it is.

I am currently having this issue but the car is not throwing any codes. I was going to start with the easy things like checking my battery and the wheel sensors. Any thoughts on what this could be with no fault codes?

Hi Eric.

The ABS unit may still be faulty. My unit threw the usual death faults but when it arrived at the great guys at ECUTesting they could find no faults. I asked them to rebuild it anyway and it now operates perfectly.

These damn ATE units are a pain on a lot of modern cars and the fault reading can be a less than perfect. I prefer to drive without ABS but it's an MoT failure.

By the way, on the refit I filled the unit with brake fluid before connecting any pipes and got away with a simple bleed job. Nice solid pedal.

Tip. If you remove the rubber water drain assembly to make pipe access easier don't forget to refit it before you replace the module. It's almost impossible to get re-seated. Ask me how I know this.......

I believe the root cause of the issue is the very low duty of the motor in normal use.

Normal use for the motor is probably 5-10 revolutions every time hill start assist is activated. The high current draw experienced during start will create some arcing on the commutator and the resultant fouling will lead to sticking brushes and a high resistance between brushes and commutator.

I had the issue. I took a 50x25mm 150mm length of wooden baton and held it against the end of the motor. 5-6 sharp hits with a wooden mallet and the reset the fault codes. Upon test drive I used the cruise control with brake assist to slow the car 10-12 times from 70-30mph, thereby running the pump for 3-4secs at a time. Every time I exit the motorway with a clear slip road, I use the cruise control brake assist to slow the car. The fault has yet to return.

Interesting...... that makes a lot of sense. Thanks for the info!

Hi guys,

Looking for some advice/help...

I have the dreaded 5DF0/5DF1 faults on my BMW 325i. For a while now the ABS, Handbrake and Traction control lights were on permanently on my dash.

I purchased a used unit (pump & module) from a breakers which matched my part number and I was told it was in good working order.

I had my local garage fit only the new pump to my existing ECU module and initially all the warnings lights disappeared however upon driving for a while the warning lights re-appeared and now come on intermittently.

In hindsight I wish I went down the ECUtesting.com route.

Has anyone on here encountered any similar issues at all or can anyone assist in any way.

Thanks

If you still have your old pump and module, send the to ECU Testing and have the pump repaired. That will minimise off the road time as you can change the pumps over in a couple of hours.

Hello everyone iím the newbie here

Anyone has the time to read this ? 😃

3 weeks ago while driving my 328i in the heavy rains i got into a tremendous water puddle and a passing by truck splashed me all over too 😏
The engine started cutting off and jumping till i was obliged to shut the car down then the engine never started and The famous DSC DBC failure occurred with ABS too the car continue to crank but never starts

The technician said it could be that water entered the engine then he told me the scanner shows the engine chain was misplaced 😳 so he took care of it and the car started normally

One week ago the problem came back in the morning i started the car DSC & DBC & ABS welcome notes came again 😠 but the car cranks and never starts

Took it to the technician the diagnosis came the car computer system (dunno the technical word)is fluctuating and if the problem reoccured it should be replaced but i didnít like what he said he seemed very unprofessional

2 days the problem reoccured this time i called another technician and the moment he opened the creamy colored box on the right side and moved the cables the car started and no more messages appeared so he changed a blue dme relay because it showed faulty on the scanner

2 days later again the same scenario and when he shaked the cables in the creamy box the car starts but in the afternoon the car did it again this time i opened the box and shaked the hell out of the cables and nothing happened

The car is now with him under supervision and itís starting fine but when i get it it fails to start in the morning

Can anyone tell me what the hell is going on ? And what should i expect ?
Please if anyone has this happening to his car and got it fixed tell me what was the problem iím confused if itís a dsc and dbc failure i get it but why wonít the car start ? Dsc and dbc failure can prevent the car from starting ? then all of a sudden it all comes back fine with no faults ?

Sorry for the long post but iím getting desperate about this ... any help
