w140 S500, 1997, cut throttle at 3500 revs and esp light
Hello, i have an w140 S500 from 1997 and at 3500 revs cut the throttle, esp are light. On the tester StarDiag show me that ESP charging pum is broken, knock sensors broken. I changed the module abs+esp, pml and the same sympthoms; the fuel pump is ok, i changed speed senzor on flywheel and the problem not resolved.
Do you thing that broken esp charging pump could be the culprit the throttle cut off at 3500 revs? The sympthom are like it no fuel enough in the tank.

I had a problem like that and it was my crank sensor not plugged in fully.I had ran over something and it pulled the plug.

Crankshaft sensor are located behind the engine? If, yes, i changed that sensor ( but is a sensor without wire, i saw on the net that are crankshaft sensor with wire ) and same problem.
