Check Engine Light Due to Faulty Camshaft Adjuster Solenoid on Mercedes-Benz C230

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.

2007 Mercedes-Benz C230 130,000 mi,
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.

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.

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 kept flashing and motor shook a lot.they should do a recall on these cars.lets all gather signatures and get a lawyer.these 2096 Mercedes c23o have a factory 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!
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 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 am having the same problem. The check engine light will begin flashing and the car violently shakes. This is not a constant problem as I have gone months in between each event.

At a light my car would not accelerate and I had to pull it over to the side of the road, turn the car off, then turn it back on again. This happened a few times. Then I received notification in the mail there was a class action lawsuit and described the problems, all of which I had. I called Mercedes and they told me it would be $4,000 to $7,000 to fix the problem. I traded the car in and bought myself a new 2016 Hyundai. Mercedes refused to recognize this as a recall, shame on them. I found thousands of people who are stuck because they can't afford the $7,000 to fix their lemons.
I'm having exact problem with w204 cgi engine year 2010.. This is ridiculous..Mercedes Benz should take responsibility..

I had this same problem. My C230 started making a noise upon starting. I took it to the dealership to be repaired. They couldn't figure it out but charged $800 for some repairs. They did not fix the problem. It continued and just finally stopped running at all. My husband decided to check it out and found out at the teeth had worn/broken off camshaft gear. Parts were hard to find. Car has been setting for a while now. Mercedes is no different than any other car out there. You get it paid for and it falls apart. If so many people had this same problem why didn't they recall?
car idling rough, ticking noise, jerking when backing up

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.
I get the obd2 code 0025 exhaust camshaft sensor over retarded Lt. Bank I've replaced both magnetic and Hallefect sensors! Still get the code! My car is not a part of the timing chane balance sprocket mod. I think it has something to do with the Transmission shift points! It's always skipped passed second gear sense I bought it! It jerks pretty hard every morning when I pull out of my garage! So I think it is disrupting the camshaft timing!

I had this same issue with my C230 on 01/19/16. My CEL came on just before scheduled maintenance A. It was determined the cause was a "CAM magnet failure" and the service technician said that when one goes out, it's best to replace all four since the labor to access one is costly; he said it's more economical to replace all four at once then to come back later to have other replaces. The cost of four was $ 855 including labor. It's too bad no one has filed a Class Action suite against MB over this. It truly should have been a recall. Now, after a little more than a month, my CEL is back on again and I have no idea what to expect when I take it back to the MB dealer. I am very disappointed to say the least.
I've replaced the magnetic solenoids on both sides and still have CEL code 0025 I just keep clearing the code! It comes on about every 50 mi. or so! I'm so sick of this! I carry my tester in my glove box to keep the cel light off!
