Open the full vehicle complaint log (all categories)THE "CHECK ENGINE LIGHT" IS ON, WHEN I TOOK THE CAR TO THE DEALER, THEY TOLD, " THE AD BLUE TANK IS CORRODED." I HAVE ALWAY FUELED WITH DISEL RECOMMENDED BY MERCEDES. HOW CAN TANK GET CORRODED SO EARLY. I SUSPECT FAULTY IN THE MANUFACTURING. I REQUEST YOU TO DO NECESSARY INVESTIGATION INTO IT. I HAVE HEARD SIMILAR INCIDENT ABOUT FAULTY AD BLUE TANK FROM MANY OTHERS ON FORUM: HTTP://MBWORLD.ORG/FORUMS/GL-CLASS-X164/396987-2010-GL350-BLUETEC-FUEL-SYSTEM-CORROSION-BIG-PROBLEM.HTML
I HAVE BEEN NOTICING AN INCREASING SMALL LEAK IN ENGINE OIL ON MY GARAGE FLOOR. RECENTLY I SAW A VERY LARGE PUDDLE WHILE PARKED AT A LOT AND HAD THE CAR TAKEN TO NEAREST DEALER. DEALERSHIP ADVISED REPLACING OIL COOLER AND ASSOCIATED SYSTEM PARTS. I BELIEVE IF I HAD NOT NOTICED LEAK/PUDDLE, ENGINE MAY HAVE SEIZED WHILE DRIVING. ALSO, ON MANY MB FORUMS, THE OIL COOLER IS IMPLICATED AS THE CULPRIT FOR A LARGE OIL LEAK. *TR
ENGINE ALMOST STALLS WHEN COLD. TOOK TO DEALER, DID A SOFTWARE UPDATE. IT IS BETTER BUT STILL NOT RESOLVED. *TR
