MB has all kinds of service bulletins on early ASR vehicles! Everything from from throttle actuators, ASR ECUs', E-GAS ECUs', etc. I just finished one today on a 1993 140. Although the vehicle needed an updated ECU for E-GAS, the closed throttle position switch(located on the gas pedal) was the reason the light was on. It passed all the standard electrical tests. I physically removed it and bench tested it to get it to fail. This was an extremely intermittent problem, but I think the recent cold weather here made it worse. Anyway, the system on your 124 should be almost identical. Codes to look for are: E-GAS/224, ASR/030. There is information available in WIS and the old Red Fiche(anybody remember those?). Good luck
