300E engine wiring harness
My 1992 300E has 80k miles. I was just told by a MB dealership that the entire engine wiring harness needs replacing. They said it needed to be moved out of the way when they replaced the head gasket and that the movement caused a malfunction.
How can a wiring harness with 80k miles go bad? If it is malfunctioning, can't the wires that are "bad" be replaced without spending $1000.00 to replace the whole harness?
