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. I HAVE BROUGHT IT IN TO MY MECHANIC SEVERAL TIMES BECAUSE OF THE HESITATION AND SHORTING THAT OCCURS - ESPECIALLY WHEN I HAVE THE AC OR HEATER RUNNING AND HAVE SPENT A SIGNIFICANT AMOUNT OF MONEY ON TRYING TO REMEDY IT BY ATTEMPTING TO RE-WRAP THE WIRING BUT IT ONLY AFFORDED ME A TEMPORARY FIX AT BEST. THE ESTIMATE I WAS GIVEN TODAY WAS FOR $1,400 FOR THE WIRING HARNESS AND ANOTHER $700 - $800 FOR THE LABOR COST ASSOCIATED WITH IT'S INSTALL. FROM THE NUMBER OF SIMILAR ANECDOTAL STORIES I HAVE READ ONLINE WHILE RESEARCHING THIS ISSUE, I WONDER WHY MERCEDES BENZ HAS NOT ISSUED A RECALL ON THIS OBVIOUS DESIGN DEFECT. *TR

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. *TR
