Dsc hydraulic unit failure

When the light is flashing, it means the traction control system has been deactivated. Exercise extreme caution while driving on slippery surfaces. BMW has a notorious fail rate with their DSC modules and may need replacement. Visit your local workshop to find out for sure.

i need anyone one to help me with this problem, i have a BMW328ci and i tried tyo get out of my house this morning and all roads were frozen and the car started sliping and i activated the dcs button and car was still slipering and then brake, ABS, CBC & DSC lights turned on and i need to know how i can reset these lights so they can come off

ABS/ASC module is faulty
CLASSIC ABS FAILURE SYMPTOMS:
- Most of the time, the problem is the ABS module or one of the 4 wheel speed sensors (& sometimes the brake pressure sensor)
- In my 2002 BMW E39 DSC, three orange (warning) cluster display lights lit, ABS, Brake, & DSC
- The 3 warning lights reset when the ignition is turned off, only to repeatedly reappear within minutes of normal driving
- The fault is often intermittent leading you to falsely believe you've resolved the problem (proper diagnosis is important)
- Sometimes the fault only appears when the engine is hot; other times only at speeds over 40 mph
- Carsoft may erroneously show a rear speed sensor failure; but just replacing the speed sensor may make no difference.
- All the work is in correct diagnosis of the problem; parts replacement is trivial (from 1 to six bolts in a few minutes)
- Hence, this BMW E39 ABS 3-warning light DIY will concentrate on understanding and diagnosis of the problem

I think you should check ABS sensor ring on the rear wheels. This is known to come loose and cause this problem. Hopefully it's just that you not the entire hydraulic unit

The flash may be a faulty brake light switch located on the rear of the brake pedal

My advice - take the vehicle to your local dealer - tell them you just want it diagniosed - agree a time of say 20 minuits. That way you will know for sure and can then carry out any diy repairs yourself BUT should it require a complete hydraulic unit which is likely as they are hmm what's the word ... ****!- contact BMW customer service for financial contribution.
