Hello. I'm new to the forums and such, but certainly not Mercedes-Benz. I'm much more familiar with the Diesels, going back to the W115. My newer gasoline Mercedes is becoming quite the headache!
I have a 1997 E320, with the M104 straight-six, and automatic transmission. The ASR light is on immediately when the car is started, and stays on. This is the only light illuminated, so nothing with the ABS or such. The car has absolutely NO throttle response. Once it's warmed up, tapping the gas pedal merely causes the idle to kind of "flutter" or "drone" up-down-up-down from then on. The car will idle around in Drive or Reverse, but at perhaps 3 MPH. There are no OBD-II codes.
I've been reading up on this for quite a while now. How do I determine what's wrong? There is no cable going to the throttle body. I swapped the brake switch with 3 known good ones. There is no place to attach the flashing LED scanner, like in the older models. How do I proceed?
