The camshaft adjuster solenoid (which is related to the variable valve timing system) may fail or timing chain/balance shaft components may wear, resulting in illumination of the Check Engine Light and various drivability issues. Mercedes-Benz has released a service bulletin outlining specific repair instructions depending on fault codes stored.

I would like mercedes-benz to make it better for all and have pride in thier cars. this camshaft proplem is wide spread and should be a recall.

Check engine light started blinking and car began to shake. Has difficulty in accelerating. When ran an engine diagnostic received multiple and several codes indicating misfires, camshaft position, timing errors, ect. Feels as if it needs a tune-up but it came on so randomly. Don't know what it can be and how to fix but afraid that its going to be very costly. More than I have or afford.

My check engine light does not come on, but codes indicate this issue. I'm guessing a clever owner disabled the indicator so as not to freak out the dealership he traded it in to. Was told that Mercedes is currently defending against a class-action suit, but obviously that'll be too late for us owners who have the problem now. My mechanic indicated that repair would cost $4,000-5,000. For a car this recent and low miles, Mercedes should indeed initiate a recall for the problem.
Check engine light came on then it went off then comes back on, took it to MB they say it is balance shaft repair cost $6,500 plus tax . Dealership said the age and miles on your car it might not be worth fixing I said it has 70,000 miles on it and it is seven years old you would think a Mercedes would last longer than that!

The engine like comes on and the car slow to shift gears and then jumps into gear. I was told that the camshaft requires replacement but was told it costs $7000 even though Mercedes acknowledges the problem and would pay 60% of the costs,.
I have a noise that comes from the top end when initial acceleration is applied. when I feather the accelerator pedal both on and off...it has a desieling sound. I have replaced the module just under the front cap but it still does it...now the supercharger is making noise and the ASR/BAS light is staying on. what is going on?

The code for the timing gear started appearing around 48K miles. Because my warranty was already expired it was not covered. The dealership quoted me $5k for repair, which I found absurd.

It has not been repaired as of yet. Still looking for my best option.

Replace one of the camshaft solenoids and now have the check engine light on.

Started the car one morning and it ran rough which made me think a cylinder coil was shot. I drove it directly to my mechanic who ran codes. Codes indicated a timing chain issue and once he cleared the codes, he asked me to start the engine one more time. It wouldn't start again so I parked it in his lot. More than 50% of the cam gears are at the bottom of the pan and the valves are bent. Deciding whether to rebuild existing engine or buy a used engine and just replace the timing chain, cam gears and cam sensors. Either way, it's going to cost me thousands of dollars. I will NEVER buy another Mercedes again. P.O.S.

CEL Light came on, would start but would not accelerate when I pressed the gas, then it would die again. I had to get it towed 20 miles to my house.
