“The engine / fuel injection wiring harness of my 1993 Mercedes-Benz 300e has cracked insulation throughout and is beginning to short out with the risk of causing dangerous engine malfunction and even fire inside my engine compartment. I have read many reports of other Mercedes-Benz cars of the same age range having the exact same defect. …”

“Fuel injector harness is dry rotted as seen in the images on this site. I just recently discovered that there is a major defect with the harness assembly due to poor workmanship this is certainly a manufacturing defect. Mercedes should replace the harness free of charge.”
