ASR and ABS light on intermittent.

[spinedoc]

I just had my 1991 500SL Motor mounts replaced, in the process some flaky wires were broken and the ASR light only came on, and the car went into limp mode. The shop replaced the wiring and now intermittently the ASR light AND the ABS light go on, if I restart the car it usually goes away.

The shop said they replaced the overvoltage relay but the numbers did not match, they called 2 mercedes dealers who said the non matching relay was the right one, and the original one was discontinued. The original relay had only one fuse, while the second one had 2 fuses. The shop thinks the new relay screwed something up and put in the old relay and told me to drive it for a couple of days. It still lights up ASR and ABS intermittent, although it does NOT go into limp mode.

Anyone have any clues?
