Hello all. I'm new to the W140 and it seems I now have the infamous ASR light on my 1994 S600. The only symptoms I have is when I first start up the car, everything is running fine, the moment I put the car into drive and start moving, within 10 seconds, the ASR light comes on and the car goes into limp mode. I'm totally new to the W140 and I have no idea where even to start diagnosing the issue. My question is, anyone have any suggestions as to where my first, second and third steps should be? Thanks!
