From the parts list you gave, it doesn't seem like the dealer's doing ANY diagnostics, just parts replacements. That's why I want to get an OBDII reader so I can at least see the codes and go from there.

You should call an M-B rep and tell them the dealer never fixed your problem when it was under warranty and demand they fix the ADS problem once and for all. With that parts list, it's pretty obvious the mechanic was clueless.

Today's new problem: I got in the car after a short drive and now the two
LED's for the suspension height switch are on, the LED for the firmer shock setting is on, no gauges work and none of the switches change the LED status plus the ESP switch does nothing. I wonder if the ASR is completly off now, I should see if I can spin the tires and whether that at least will activate the ESP light in the speedo. Another funny thing is that the odometer and trip odo are lit, but the number don't increment either. I guess if you could go with out gauges you could fraudulently disable the odo.

I hope it's only a blown fuse, It's too dark to check tonight.

Finally, I bought a new antenna mast because it stopped going up and down, when I put it in it never catches so I took the antenna apart and there are two nylon gears inside and one had a little tab break off. New antenna from dealer, $600! I ordered the gears from antennaworld for only $30.

Fun stuff.
