[W124] Wiring harness

[Felix]

I'm having start problems with my car and I found the cam sensor wiring is exposed with a few wire strands broken in a couple of places.  Can't tell if it's disintregrating or if it was severed somehow.  I only see one wire to the molded plug.  Is this repairable or part of the harness that's sold separately?  What's the page # in the service CD?  

Thanks,
Felix

 The problems with the early failure of the wiring harness are well documented.
  
  What is not often realised is that the wiring which connects the throttle body to the main harness can also fail causing all sorts of running problems. Perhaps you might have this looked at.
  
 I do beleive, however, that this short section of wiring can be replaced by someone with some skill with a soldering iron - you do not want to have to replace the complete throttle body !

 Hello all,
  
 I recently had the wiring harness replaced on my 1994 C320 coupe. The technicians are having problems solving a mystery involving the "Check Engine" light. They couldn't nail down the problem. It seems the computer isn't as sophisticated as the newer cars only offering 16 fault codes. They told me during the mid 90's the German govt. mandated wiring harness' (among other things) must be biodegradable. The problem is they degrade while in the car, potentially causing all manner of problems. This little repair cost me $1600 U.S. Mind you, this service was performed at an independent garage. This didn't solve the "Check Engine" lite burning, but now the tech's think they'll more easily be able to localize the fault. I have some Mercedes-Benz buyers guides that mention wiring harness problems due to heat, but never mention idiot government interference in design as the problem. Comments?
