Brake warning lights??

[Seand411]

Over the past week 3 yellow warning lights have come up on my dashboard and then disappeared ?? It's the traction control light , the ABS light and the yellow handbrake light . According to the manual it's a warning for the brake malfunction something to do with driving aids malfunctioning. Three times the light has come on then gone off. :/ I've noticed no difference in braking performance... I'm baffled... It's booked in to the local garage tomorrow morning but just wandered has anyone's Z done this before and what might be the cause???

Cheers

I've had this and traction control is disabled when they light up!

Strangely for me I had low pressure in my drivers rear tyre and that seemed to be the culprit. I was getting these lights come on every time I drove for a round 3 weeks before I decided to check tyre pressures...lol

It can also be a dodgy sensor somewhere

It can also be a dodgy sensor somewhere

In particular, be sure there isn't crud around the ABS sensor, the fronts in particular. Crud attenuates the signal it's supposed to sense.

So the cars been into the garage and... It's not good news

Error code

5DF0 hydraulic pump motor
5DF1 undocumented code

According to the local garage it's a big job and they don't have the equipment to re program the unit once fitted .. So it looks like its either going to BMW or a specialist ... Has anyone had this happen to their car? Is it a common problem ie BMW contribute to the cost of repair?

Gutted

Gutted for you.

"undocumented code" -- how helpful.

Grasping at straws, but all the control module can sense is various electrical signals are normal or not. It can't physically "see" an actual defect in a motor, only that the electrical characteristics are not normal. Meaning locate all related electrical connectors, disconnect, examine for damage, dirt, moisture, etc. Reconnect and hope that does something. Long shot, but worth a try, cheaper than a pump motor.

Also, see if you can invoke the ABS operation on a dirt or gravel road, or even a wet, sealed road. If it works, I wouldn't be in a hurry to replace the pump without more evidence.

Think the fault codes are red herrings here - get a diagnostic done at a BMW dealer or specialist to get to the real fault . Still might just be an ABS sensor.

I had these lights - in my case it was triggered after changing the steering rack and the dealer forgot to reset the steering sensor ...,

Hope it works out for you

It's booked into Hughes brothers BMW specialists in Derby. They came across very knowledgeable over the phone and said the abs sensors were very prone to go on Bmws so hopefully it's just a sensor. Booked in for 4/10 as that was the earliest appointment. Fingers crossed theres not too much damage to the wallet

Cheers for the replies.

A pound to a pinch of Poo its no 2 here, DSC Pressure Sensor

http://www.realoem.com/bmw/diagrams/x/q/153.png

Had mine done 3 - 4 weeks ago took 20 minutes and cost £135 inc VAT at Autotech Telford problem sorted

Mines gone again this time claening sensors did not work but pull off no 2 pressure sensor fixed it for a day or two, so does look like i hope the no 2 sensor on the master cylinder, must book in to the indy to be poss,looks like out with the spanners again!!

 

[TINO]

If it is no2 and I replace myself will this fix or will the light still be on and :? have to be reset??

 

[Seand411]

So .... It's grim news..

Garage have had the car in today and concluded that its a hydraulic pump failure along with failure in the modulator. To fix its 1400 for the part plus labour .. So gutted

I noticed that DrNick (forum member) had this problem and had 80% funded by BMW so ill be in contact with him as to how they managed that ...

 

[Seand411]

... According to the specialists the repair kit that's available is not compatible :/ ill know further when I collect it tomorrow morning.

 

[Seand411]

It's been taken to Sytner Nottingham who have confirmed the same fault .. Given an a quote of £2072 to fix. I've requested they ask BMW for a contribution ...

A week later Sytner ring to deliver the good news ... BMW have made a good will gesture of paying 80% of the part leaving me with a bill of £550 .. RESULT!! Still a bit gutted I have to fork that out but it's a lot better than £2072.


So if anyone's in the same boat with the dsc module fault. It's worth a go!

Hi
I have the same codes and lights on dashboard with my 07 Z4. Going to have to send to dealer. How did you manage to get the price reduction?
Thanks
Roy

Hi

Due to my car having FSH with the dealer I requested Sytner to ask BMW for a good will gesture towards to cost of repair... Luckily for me they agreed and contributed. Speaking with the repair technician the fact I have FSH with a dealer would have made a major part in their decision.

Any more queries let me know?
Cheers
Sean

Thanks for your reply. I'm hoping the abs/handbrake/traction lights on the dashboard and error codes are red herrings since in addition to the 3 lights I'm now getting intermittent yellow bulb and windscreen washer alerts....also finding roof struggles to close. Some forum members have suggested it could be the battery but I've just had the car through its MOT and full service at an independent garage and they confirmed the battery was OK. The garage suggested I take it to a dealer because one of the error codes points to hydraulic pumps which were beyond their abilities. I just think it's too much of a coincidence that I'm also getting the light bulb and windscreen alerts. Time to take it to a dealer I think, unfortunately I don't have FSH with them.

The ABS, Hand Brake and Traction control warnings lit up today on the motorway. After parking up, left the car for a while and then went back out, tried the full lock each way and the lights went off. Think it may be a faulty ABS sensor, will see if it comes back on again....

Sorry to bring this post to life but I think I'm starting to have a similar issue. It's happen twice over the past few weeks. I replaced the batter thinking that was causing it but it just happened again. Same 2 or 3 lights come up, it so hard to see as it happens at the blink of a eye and the radio cuts out for a split seconds, that's what draws attention to you. I don't think it causes power loss, but again so hard to tell because it happens so quickly. Has anyone else experienced this? I don't want to go on a while goose chase. Thanks in advance.
