I was inspecting my car to prepare for a smog check.the check engine lite was on. I noticed that the wires going to the air pump had no insulation on them. I cut into the harness to find all of the wires were disintegrating. I ran the code check and got 3 codes. 4,5,and 18. One was egr failure which is common. The other two were air pump and auto cam timing advance failure or shorted out. The wires to these components have no insulation on them. If mercedes didn't know this was a problem why did they afford a specific code for a shorted out smog component?

I have a 1994 e320, im going to sum this up, the harness is junk, my car stalls on the freeway, uses up gas like a running hose, got 6 miles on 12.00 worth of gas, lights flicker, when I cut back the tape it looked like someone put cig tobacco in the wire, then I looked and it was the insulation that had turned to nothing, all wires are rubbing. The fuel inj. Get floods with oil,gas. Its a mess and they want over 1000.00 to get a new one. Recall this harness before people start to die.

1. Multiple warning light alarms over 12 month period. 2. After many fruitless and expensive repairs of sensors, the problem was traced to a defective engine main wiring harness, where the insulation on individual wires had largely disintegrated. This was reportedly due to use of defective insulation at the time of manufacture, which over time and normal use, would disintegrate and break off, enabling individual wires in the harness to short together. The repair facility had maybe 20-25 of these failed harnesses hanging on the wall as a display - this is in a small town, so the total number must be very large in the USA. Mercedes benz refused to take responsibility for the problem or the repair, claiming essentially that in 10 years from manufacture date, anything can happen to a vehicle and that is not their responsibility. This failure produced unsafe conditions, the car would fail to start, stop running on the road and would fail to restart, etc. 3. The wiring harness was replaced, at my cost of close to $1000. The problem has not recurred since. The old part is still available for inspection.

I was getting the car dyeing in the middle of the road, and at stop lights and smoke out from under my hood, then took it to mechanic who told me of a problem with mercedes wiring from 91-96. This is a well known problem that mercedes will not fess up to!!! The harness cost me over $600.00!!!!! For what they probably paid 10.00 to have made for them. Where is my government to protect me and others for what is obviously a well known problem with these vehicles? Does someone have to die before it gets looked at seriously? Go to any mercedes forum and there will be pages upon pages of complaints about this very problem?????!!!!!!!!

My 1994 mercedes-benz e320 cabriolet has a check engine light on. An investigation leads to disintegrated engine wire harness, that is shorting. The vehicle is running rough and stalling. There is a potential for a fire hazard. The car stalled on highway, causing me to loose control and crash into a side pole, damaging the front of the car.
