ASR light comes on...loss of power
On my 500 sel (1993) ASR light comes on randomly accompanied with loss of engine power. Only if the engine is turned off and restarted does the light go off and then engine runs normally, until the next random episode occurs. This seems to happen freuently at driving constantly at high speed, i.e. on the freeway. So far has not happened in city driving.
Dealer cannot diagnose this problem and has replaced computer at cost of $3000. Another mechanic has changed throttle actuator at cost of $1000. Still have same problem.
Anyone seen this problem and any ideas?????????
