What is DSC? DSC, short for Dynamic Stability Control is a suspension control system which goes beyond the single components of ABS, Cornering Brake Control (CBC) and Automatic Stability Control. It works by monitoring each wheel speed individually along with yaw rate and longitudinal and lateral acceleration through various sensor.

Dynamic Stability Control (DSC) is BMW’s version of this safety net on your car. It’s automatically activated each time you start your BMW.
The Dynamic Stability Control module also receives information from vehicle speed and engine speed, throttle position, brake pedal position/force and the steering angle sensor. All of this information collected is fed to the DSC control module and process.
The DSC computer constantly calculates an ideal driving condition that is compared with the current status. If the vehicle oversteers or understeers, the calculated ideal deviates from the measured status, and DSC will intervene within a few milliseconds via the engine management system by either applying brakes at different wheels, cutting fuel, and a few other methods that are too detailed for this short presentation
Dynamic Stability Control is a setting that has the ability to keep your BMW in line within the laws of physics. It’s a controlled, keep the car on the in intended path kind of setting which is what you want the majority of the time. The DSC system will use the brakes, individually, if needed, to keep a wheel from slipping if power is over coming grip.
Dynamic Stability Control can even decrease the power to the wheel if it detects wheel slip. Add the all-wheel drive system and it gets even more complex. Essentially what DSC means is no tail out drifting and no donuts in the snow. It has the ability to sense if you are about to spin the car and intervene again by monitoring the yaw of the car, the input of the steering wheel and the gas pedal.
DSC is a great safety feature in any car and it has and will save many cars and their passengers.
what is being showed in that picture??
The DSC feature is the bane of my E46 existence. In Seattle on hills during rain it can cut power so severely to the engine on slippery streets that the car’s engine feels like it is at the point of practically dying. I wish BMW would give me the option of controlling the degree of DSC’s severity, other than just on/off.
@ Hoiser: BMW does let you control the degree of DSC, sort of (excluding xi models). Press quickly and I believe it turns off DSC but leaves ASC on. Hold down DSC for 8 sec(?) and it turns off DSC and ASC.
absolutely current
@Frederico Silva:
i dont know.
@Frederico Silva: Just a photo that we decided to use….I don’t think it represents anything.
It is snowy in Scotland right now, and I turned on my DSC (330d) going up a slight snowy (thankfully wide) road in Aberdeen today. Bad move. The car within about 5 seconds had kicked out the rear end about 30 degrees! (driving straight on a straight road)I had to react pretty quick to steer into and correct it. Within another 5 seconds the same happened, the tail kicked out (either FR brake or RL accelerate) and again I had to correct it pretty quick. It was pretty darnn severe. DONT PLAY WITH IT WHEN ITS SLIPPY!
I also drive with it off… same experience
Incorrect.It may be better to disable the DSC under certain conditions – especially in the snow.But you have to know what you’re doing(Be a competent driver).Many inexperienced drivers give too much throttle, don’t know how to steer or hit the brakes when the start panicking – all behaviors that should be avoided.I’m pretty sure that if you practice a little bit, you’ll be able to control your car in any condition even with the DSC off.After all, the DSC and the ASC(its predecessors) wheren’t present in older BMWs but people drove them anyway even in the snow.

My warning light showing DTC deactivated has come on Does anybody know how to reactivate this
fix one of your ABS sensors.
DTC deactivated?What car do you ride?
I can’t wait to finally figure out what is wrong with mine so I can get rid of this lemon and buy a reliable car. So far I’ve spent over $2000.00 dollars trying to fix this POS, taken it to three different shops including a well known and over priced dealer and no one seems to be able to figure it out. Every time we fix one extremely expensive component the damn thing tells us that it is now something else. I’ve spoken with BMW North America they flat our refuse to stand behind their product. This car only has 53,000 miles on it! BMW is obviously not what they use to be. They sell garbage at jewelry prices. If your lights are off, sell it now. Its only a mater of time until it starts bleeding you dry.
I have a 2000 X5 it has been the best vehichle I have ever had. I would not change a thing about my BMW X5 with over 250,000 miles no lights and no problems. Im not sure why you are having problems. All my friends with BMW’s dont seem to have any problems either.
Has anyone had he following three, the 4×4 light, the airbag light and the fan on high almost immediately the engine starts?
Steering angle sensor has now been replaced but the diagnostic is still saying it is a fault?
Sorry, it is the 4×4 light, the airbag light and the orange brake light, and then the fan
Hi ,just want to know how to on my DSC?when I’m hold it in few second,it came out FAX deactivated‘.
Your DSC is constantly on.You have to disable it by keeping the DTC button pressed.One-time pressing enables the DTC.Keeping the button pressed for about 5-10 secs disables the DSC completely – DSC warning light goes on on the dashboard.
Sorry,is ‘DSC‘ not fax.
Does the DSC-unit require special maintenance, in order to avoid any problems?
Nope.
what happens when there is water inside the DSC system, do you clean it out and the car is fine, needs to be done
Water inside the DSC system?OK.HOW?!
Hi, I want to understand this DSC cause it reflex the sign on my clause when I’m driving what is it?
It means that the DSC kicked in since you where about losing the control of your vehicle.If it blinks, it means it kicked in.
[…] devices can be cleaned using a specialized fluid created for this purpose. If cleaning does not work, then you will need to replace them entirely. […]
