“My 1993 mercedes 300e experienced some major problems with its wiring in the harness. As a result, I had it taken into a mechanic, who noticed that the insulation on the fuel injection wiring harness deteriorated and caused the wires to rub together. It appears that this engine wiring harness problem has been an ongoing issue with many mercedes (especially the models from the 90's), and I am surprised that mercedes benz has not made any effort to recall this problem, or at least to even acknowledge this as an ongoing problem. …”
