What are the symptoms of a Mercedes W124 harness failing?
The typical symptoms of a failing harness are electrical errors, problems with starting the engine, poor running and rough idle. Before buying a 1992-1996 Mercedes-Benz W124, check if the harness has already been replaced. Otherwise, you will have to replace it yourself.
Is the Mercedes Benz W124 affected by the facelift?
The post-facelift W124, called the E-Class, is affected by this change. Unfortunately, the new paint offered far less protection from rust. The pre-facelift W124 models had reasonable corrosion resistance, but because of their age, you should still pay a lot of attention to any rust spots and the condition of the floorpan.
