THE CAM SENSORS ON THE MERCEDES M271 ENGINE LEAK OIL WHICH SPREADS TO OTHER COMPONENTS VIA THE WIRE HARNESSES CONNECTED TO CAM SENSORS. OIL CONTAMINATION WILL DAMAGE OTHER ELECTRICAL COMPONENTS (NAMELY THE ECU AND EXHAUST OXYGEN SENSORS) IF THE CAM SENSORS AND WIRE HARNESSES ARE NOT REPLACED. A NEW CAM SENSOR AND WIRE HARNESS HAS BEEN DESIGNED AS THE CORRECTIVE ACTION. THE DEFECTIVE CAM SENSOR AND WIRE HARNESS WERE USED ON THE PREVIOUS ENGINE DESIGN (M111). THERE IS A TECHNICAL SERVICE BULLETIN FOR M111 ENGINE BUT NOT THE M271 ENGINE. MERCEDES REFUSES TO RECALL THIS DEFECTIVE DESIGN ON THE M271 ENGINE CAUSING OWNERS TO PAY FOR THE $900 PREVENTATIVE MAINTENANCE. WITHOUT THIS REPAIR THE ECU (PART COST $2000) AND OXYGEN SENSORS (QTY 2 @ $238 EA) WILL BE EVENTUALLY DAMAGED AND WILL NEED TO BE REMOVED AND REPLACED. WITHIN THE PAST WEEK, PAID MORE THAN $ 2,400.00 TO REPLACE 2 CAM SENSORS, 2 OXYGEN SENSORS, AND WIRING HARNESS. REPAIR SHOP SAYS THAT THIS IS A DEFECT THAT MB HAS KNOWN ABOUT FOR YEARS. *TR

C230K COUPE AT 73,000 MILES WITH SUDDEN VALVE GUIDES WORN BAD CYLINDER,COMPRESSION LOSS RECENTLY IN APRIL I WAS CALLED INTO MBZ FOR A RECALL ON A VACUUM HOSE, HERE I AM A FEW MONTHS LATER AND I'M DRIVING AND MY CAR STARTS SHAKING ,IDLING STRANGE AND THEN I TAKE IT TO A MECHANIC AND HE FIGURED IT AT FIRST GLANCE IT MAY BE WORN VALVE GASKET SEALS AND I SAID OK LET'S CHANGE THEM AND PUT IN NEW PLUGS TOO...THEN HE CHECKS THE COMPRESSION AND DISCOVERS THAT IT IS HALF OF WHAT IT SHOULD BE, WHAT? WHY SHOULD THE CYLINDER HEADS BE WORN AND NEED TO BE REPLACED FOR NEARLY $3000, ...THIS SEEMS TO BE HAPPENING TOO MANY OWNERS OF THIS MODEL ON HERE AND MBZFORUMS FOR THIS 2003-2005 YEARS. LOSS OF COMPRESSION IN ONE OR MORE CYLINDERS. THIS SHOULD BE RECOGNIZED BY MBZ AS A DEFECT AND SINCE WHEN DO THESE ENGINES FAIL AT 50,000OR EVEN 80,000? I FEEL THIS SHOULD BE PAID FOR BY THEM, THIS IS RIDICULOUS AND SHOULD NOT BE HAPPENING AT THIS MILEAGE!! DEFECT,FLAW IN DESIGN...THEY NEED TO STEP UP AND ADMIT IT AT MERCEDES HEADQUARTERS. PLEASE HELP US OWNERS , THEY ARE GETTING AWAY WITH THIS, MENTIONING VACUUM HOSE RECALLS ON THIS 2003 YEAR BUT SOME DEALERS HAVE RECOGNIZED THAT THESE ENGINES ARE DEFECTIVE AND A RECALL NEEDS TO BE DONE ON THESE VALVE GUIDES/CYLINDER HEADS. WHY IS IT THAT THERE IS AN INCONSISTENCY ON HOW THIS PROBLEM IS RECOGNIZED BY THE DEALER AND HANDLED. SOME ON THE FORUMS HAVE SAID THAT THE DEALER SCREWED THEM IF THE 50,000 WARRANTY IS OVER AND OTHERS HAVE HAD THE PARTS ONLY PAID FOR

JUST LIKE OTHER REPORTS HERE - ELECTRICAL MALFUNCTION. 50K MILES. TOOK TO MB DEALER FOR ROUGH IDLE AT COLD START UP AND LOW SPEEDS; LOUDER THAN NORMAL IDLE AT START AND IN REVERSE. NO CHECK ENGINE LIGHT, NO ERROR OR PROBLEM INDICATED IN DASH AT ALL. SAME DIAGNOSIS - DEALER REPORTED CAM SOLENOIDS LEAKING ENGINE OIL INTO THE WIRING HARNESS SHORTING HARNESS COMPONENTS (O2 SENSORS ETC.), HIGH $$$ $3600-$4000 REPAIR. ISSUE SHOULD BE RESOLVED AND PAID FOR BY MB SINCE THIS IS KNOWN DEFECT THAT SEVERELY REDUCES THE DRIVE-ABILITY AND VALUE OF THE VEHICLE. *TR
