CHECK ENGINE LIGHT CAME ON, TOOK THE CAR TO MY MECHANIC THAT WORKS ON FOREIGN CARS, HE INFORMED ME THAT MY DRIVE CAM SHAFT IS "RETARDED" BASICALLY STATING THAT MY SPROCKETS THAT HOLD THE TIMING BELT ARE WORN DOWN, I AM ALSO LOOSING COMPRESSION. I TOOK IT TO THE MERCEDES DEALERSHIP AND THEY TOLD ME THEY WILL GOODWILL THE REPAIR IF THAT IS REALLY WHAT IS WRONG WITH IT. THEY HOWEVER PROCEEDED TO TELL ME THAT YOUR CAR HAS ALMOST 100,000 MILES ON IT, SO IT MAY JUST BE THE TIMING BELT IS WORN DOWN.(THEY WILL TRY ANYTHING TO GET OUT OF THE REPAIR). THEY TOLD ME THAT THEY NEED TO CHECK THE RECORDS TO SEE WHEN THE CAR WAS SERVICED AND ALSO THAT SINCE I DID NOT PURCHASE THE CAR FROM THEM THEY DO NOT HAVE TO DO THE WORK. *TR

2006 MERCEDES BENZ R350 STALLED IN THE MIDDLE OF A RESIDENTIAL INTERSECTION SHORTLY AFTER THE CAR WAS PURCHASED. WITHIN A SHORT PERIOD OF TIME AFTER GETTING THE CAR, WE ALSO FELT A STRONG JERKING THEN SHIFTING GEARS, BUT IT WAS DOING IT ON ITS OWN. WE TOOK IT IN AND WAS TOLD IT'S JUST LOUD. THEN WE WERE TOLD THERE WAS A RECALL. THEY WERE SUPPOSED TO FIX IT BUT IT NEVER STOPPED. THE CHECK ENGINE LIGHT CONTINUED TO COME ON. OTHER ISSUES RELATED TO THE ENGINE HAD TO BE FIXED RATHER QUICKLY. THE CAR WAS PURCHASED IN THE END OF 2005, AND HAS 88,000 MILES. OVER A YEAR AGO, THE CAR BEGAN IDLING/SHAKING REALLY BAD. I CALLED MB ROADSIDE AND WAS TOLD THAT IT WAS PROBABLY BECAUSE THE GAS CAP WASN'T PLACED BACK ON THE CAR CORRECTLY AND GAS WAS LEAKING. I HAD THE CAR CHECKED AND THERE WAS NO GAS LEAKING. THE CAR WAS TAKEN TO THE DEALERSHIP WHERE I WAS TOLD THE INTAKE MANIFOLD WAS BROKEN AND NEEDED TO BE REPLACED BEFORE ANYTHING ELSE COULD BE DIAGNOSED. THE CAR IS STILL IDLING BAD AND CHECK ENGINE LIGHT IS ON. IT IS NOW BACK AT THE DEALERSHIP IT WAS PURCHASED FROM FOR A DIAGNOSIS, WHICH I SHOULD RECEIVE TOMORROW. *TR

THE VEHICLE INDICATED CHECK ENGINE LIGHT AND THE ERROR CODE SHOWS P0016 WHICH IS SHAFT BALANCE ISSUE. THE DEALER AND MANUFACTURER WOULD NOT ATTEND TO IT DESPITE THE FACT THAT IT A KNOWN ERROR FROM FACTORY. THE ISSUE WOULD REOCCUR BECAUSE OF POOR MATERIAL AND COULD CAUSE THE CAR TO STALL WHILE IN TRAVEL.
