Hello,
I own a beautiful 1992 300D 2.5 Turbo which has treated me very well. Lately, however, I have come across a problem. The car shakes at idle after about 20 minutes of driving. I took it to my mechanic who suspected it was the OVP Relay and we replaced it but the problem still persists. We also suspected it may be the ABS relay but it was not.
The wierd thing is as then when the car shakes the RPM does not fluctuate at all, it still stays at the same spot. And, it is intermittent! It will sometimes stop shaking and then start again.
Would it be the wiring harness? Or could it be an engine mount? I am really worried about this car. Please advise
Cas.
