1992 500SL ASR Problem


Finally the problem with the ASR has been resolved.

The shop diagnosed the components listed below with no success:

Over voltage Protection Relay
Neutral Safety Switch
Stop Light Switch
Crank Sensor
Electrical Accelerating Unit Computer
ASR sending unit
Alternator Test
Battery Test
ASR wiring harness

The problem was finally pinpointed to the ASR Motors: Part # 0005453165, they were replaced with new units, but it seems that the new motors were defective, the shop replaced the motors with a new set and the problem has not occurred. The cost was under warranty.

One of Sherlockian quotations seems appropriate to my problem:

We must fall back upon the old axiom that when all other contingencies fail, whatever remains, however improbable, must be the truth.

Hope this helps other with similar ASR problems.
