Wiring Harness problem
#1
![Angry](https://mbworld.org/forums/images/icons/icon8.gif)
I have a 95 S600 coupe that I cannot get the ADS light to stay off. I took it into the dealer and they told me that the car nees a new wiring harness. This really ticks me off because of a car that have less than 100k miles on it and cost over 100k new, to have a major problem like this when it has been serviced properly. Any ideas of what to do other than the obvious? Help !!!!!!!!!!

Hard to see how those are related w/o more information
The wiring harness issue that plagues W140s up to 1995 is typically the engine ignition wiring. The wires are directly subjected to the engine heat.
Just how did they get from ADS light to needs new wiring harness? You need to understand this, and so does anyone else to really help you out. My ADS light was on, and an independent shop told me that the fault codes indicated a bad right front acceleration sensor. I've done nothing for now. My light is intermittent. Are there fault codes stored that the dealership can read out?
I wouldn't do anything until you know more.

Brett, thanks for the reply...That is a very good question, I guess they couldn't figure anything else out. There were some fault codes that they came up with, but they said that they were caused by the faulty wiring harness giving off false reads. I think that they are really full of crap.......
Yeah, mine is intermittent also and it drives me crazy. I guess I can deal with it until I can find someone who really knows what is happening.

I would speculate that they might be referring to the less critical suspension wire harnesses, not the body harness. Those repairs are much less expensive. Obviously, such a fault would not render the symptoms that I described in my previous reply.
