ASC light is part of the ABS system. ASC means slip control system.When this light comes on because it is integrated with the DME or for a better term ECM (control module) It commands trottle reduction. The ASC uses the wheel speed sensor your only fix is get the ABS or (brake inspection) look at The computure engine management thinks you are slipping.

bmw 316i se blower not working ,where is the fsr located any help would be helpful thanks

check engine light?

i dont know about that but if its on that means that you have some senser failing its test maybe wheel speed senser.

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

Check to see if your brake pads and rotors are in good condition. Or if you have replaced the pads yourself and have not reset the wheel sensors this would cause the ABS Antilock Brake System light and the ASC Automatic Stability Control light to stay on as the ASC uses the ABS brakes with computer assistance to control the traction of the car if not fixed it can effect your rev limiter slowing performance

check the induction kit, where the big black rubber hoses pipes connect to air filter box and inlet fuel manifold ?? i cant remmber wat is called (sorry),if is spilt that the reason u will lose the power ,if u dont find anything spilt ,is could be possile spark plugs lead need replacing

Unfortunately there are several possibilities that are common to causing the light to come on. I would suggest taking the car in to a dealer and having them read out the fault memory. Such possibilities are a failed speed sensor, a binding DSC/ACS actuator cable, or faulty DCS/ASC control unit. If you know how, you can disconnect the speed sensors, and check for voltage output across the the terminals inside the connector going to the speed sensor while rotating the wheel. A dealer should charge you about an 1hour fee to check out your system. Due to the cost of parts involved, I would recommend having it checked before just guessing.

when the check engine light comes on means its a sensor could be going bad,,, to find out what it is you can go to autozone they will check it for free and tell you whats wrong..... same with the ABS will tell you which whell sensor or other part is bad..... hope this helps
