I have a 1989 300se. Driving it down a mountain and accidently hit the gearshift into nuetral. Went to put it back in gear and spiked tach to redline. The engine shut down, and I had to pull off the road. Tried to resart, but the starter just spins without engaging. Everything seems fine, and talking to MB dealer service says they think something is out of whack with computer. Any help?
