“Crankshaft balancer failure- mercedes E320 1999 (from individual experiences of several mercedes customers with 320 v6 engine on w210 platform and others). Around 72000 miles, my vehicle crank shaft balancer pulley started sperating a thick black rubber ring, which is sandwiched between the cranksfat and the serpentine belt pulley on the outside, belt burning smell and clicking noise which quickly turned into a knocking noise recognized as I was driving at very low speed, luckily. …”

“Crank position sensor (cps) started to fail when the outside temperature was above 95f. Car (1999 mercedes benz E320) failed to start twice when parked after driving for a short distance. Only after cooling it would start again. At one point the engine became very erratic while in traffic. At another point I was stopped on the traffic light and the engine just stopped running. Fortunately I was near home and after waiting a few minutes it started again. It was embarrassing to say the least , having a mb car stall in front of other much cheaper cars on the traffic light. …”

“As I was accelerating onto the freeway, I heard a loud noise from my engine. I started losing power steering and my battery charger light kept flashing indicating a problem with the crankshaft pulley. Luckily I was able to get home safely. After safely driving home, I looked under the hood and noticed huge chunks of rubber parts inside. I took the car to the mercedes dealership the next day and was told that the harmonic balancer had been damaged. When the harmonic balancer was damaged, it in turn ruined the oil pan cover and the timing chain cover resulting in a $2500 repair bill. …”
