Was there ever a fix/outcome on this?
The ASC light has been on since I bought my 525 e34 last August. ABS works fine, as does the speedo. The actuator cable is not broken and is adjusted per spec. and the throttle position sensor has been replaced, as has brake fluid & the pads are fine, all tyres even, same size/brand.
When engine is first started (not in gear) the light is off and can be turned on and off via the ASC button. Now, give the engine a blip of the throttle (over 1,100 rpm) and the light comes on and stays on - because of this I cannot see its an ABS sensor, and must be a faultly ASC unit as far as I can deduce.
Any thoughts? Are these simple to replace? Is a 2nd hand one likely to be good or are the units prone to failure?
