dynamic brake control

makkan00 · 12-17-2012, 03:04 PM

There are many reasons for it. Anything from poor battery to ABS / DSC problems...

What is the condition of your battery?

lemonukas · 12-17-2012, 03:46 PM

You need to check fault codes.
Do you have any braking simtoms.
I had same Christmas tree lights on my dash for more than six month. I changed speed sensor. I dind have time to change wheel bearing, but when I changed wheels from 158 to 194 it disappeared. My fault was 5dc2 that's rear wheel.

another image with codes, was just wondering if someone had the same errors before and the cause

Nickc123 · 12-17-2012, 03:56 PM

I think the abs is disabled for obvious reasons, I was thinking abs sensors maybe?

NotNormal · 12-17-2012, 04:02 PM

More than likely an ABS speed sensor failure .... He one on mine the other month.

Have the codes read, go form there

xenon · 12-18-2012, 02:36 AM

Definitely a wheel sensor.

makkan00 · 12-18-2012, 11:05 AM

Have you changed your wheels recently? Winter tyres?

Nickc123 · 12-19-2012, 01:57 PM

had codes read its pointing to something on the left rear , i presume its just the sensor what goes not the hub?

NotNormal · 12-19-2012, 02:22 PM

It'll be the sensor unless yugave had the hub off or replaced

Strangely enough, that's the same as mine I had replaced

Nickc123 · 12-19-2012, 02:33 PM

do you know if the error self clears once the sensor is replaced ? presuming it is the sensor which is at fault. ps nope not touched the hub just decided to go haywire leaving work

NotNormal · 12-19-2012, 02:37 PM

It'll need clearing

Nickc123 · 12-20-2012, 07:22 AM

Code was 5db2 going to replace sensor today hope that solves it

lemonukas · 12-20-2012, 12:54 PM

If not than you need to replace wheel bearing, because inside bearing is that tooth.
If is bearing than don't by from bmw, because I paid about Â£70 only for bearing, than you need to buy new nut and locking ring.
When I bought it I looked at bearing to find out is made by FAQ.
To change bearing is about 2.5 hours for garage.
You need find some one with who you can swap wheels, because tyres can give that fault. That's on my experience.
Bmw car is most sensible of my all owned cars.

Nickc123 · 12-20-2012, 01:51 PM

got the light cleared sensor was changed and its still come back on

idnan · 12-20-2012, 02:14 PM

Quick google suggests the code means the following:

5DB2
Wheel speed sensor pulse wheel (rear left)
plausibility – tooth fault every wheel revolution

So as one of the previous suggestion was, maybe the actual ring is faulty on the driveshaft?

Also, if you use a proper BMW software, you can see the actual live values for each sensor and can see the issue as you drive.

Nickc123 · 12-20-2012, 03:38 PM

can anyone confirm the above is the sensor and ring two different errors?

NotNormal · 12-20-2012, 03:48 PM

5dB2 Left rear wheel speed sensor; periodical control

It would suggest debris possibly has got into the unit - worth a clean out before hub purchase

I think is same error code for both.
Before you change bearing. You no need to change hub. Because that tooth is in bearing. But try to clean inside where sensor sits. Swap wheels.
