Four problems related to wiring have been reported for the 1996 Mercedes Benz 320. The most recently reported issues are listed below.
Wiring harness is disintergrating. Car runs very rough. Visible bare wires. Check engine light comes on and goes off. Smells of burning wire.
Car went completed "dead" at stop sign. Could not restart engine. Called mechanic and wires within engine wiring harness had shorted out due to wire insulation cracking and breaking off and shorting with other engine components. Mechanic stripped out wire and spliced it. Stated the wires are in bad shape due to the type of insulation mercedes used from 1991 to 1997. He stated I should replace the engine wiring harness as it would continue to short out components and would be not only a driving hazard but also a fire hazard.
My car appears to over heat, but it's actually just the temp gauge jumping around erratically. The mechanic says it's the wiring harness - a known problem in these cars which is being ignored by the manufacturer.
Cracked wiring harness. Discovered when rear lights would not work.
