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 car

I have a 1999 BMW 323I five speed, but when ever I shift to 3rd gear the asc light comes on and the car will not pick up speed


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.

I have bmw 530d and abs asc and other 1 its on after 2 miles i been on service and mecanic sed presure sensor interference,i change presure sensor and delithed all cods but its on agan.


Hi.The problem of your car sounds like a faulty ABS/ASC control unit. It is the common problem of this model cause the Control Unit is too close to exhaust manifold resulting to dammage internal parts of ABS/ASC control unit. But although this is the common problem of your car, I still suggesting you to re-hook up diagnostic tools and double check the condition of wiring harness, plug connections and power supply of related fault codes you will retrieved and if the problem still existing then I recommend you to replace the ABS/ASC Control unit and do Coding for new control unit.
I hope this tip will help you to solve your problem.
Thanks

Have replaced ABS module on bmw 525 E39 and ABS now ok, but the ASC lamp will not go off on the dash and fault code 23 (incorrect coding) will not clear from system? Everyone told us the ABS ecu does not...


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

Recently got a 1999 m5 the asc indicator does not go off even if the button is pressed .Can anyone tell me why? thanks


the ASC is for auto stability control,,you probably got a bad sensor, anything from abs to height sensor,,,,,you need to get the car scanned to see what then code is,,thats why the light is on,,it disables the asc and abs

BMW (e39 1999) eml and asc lights and in limp mode


Check the ABS brake sensors in your wheels, if they are not functioning properly. It will trigger the computer to engage the ASC auto stability control light as the asc uses the brakes to assist in control. I will also engage the EML engine management light to slow the rev point to limp mode

ASC & ABS light on cluster


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
