Mercedes-Benz C230 Problem Report
Mercedes-Benz C230 Check Engine Light Due to Faulty Camshaft Adjuster Solenoid
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. - Visitor
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. - Visitor
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. - Visitor
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! - strunkmms
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. - Visitor
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,. - Visitor
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? - maxmload

car idling rough, ticking noise, jerking when backing up - tbgoode01
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. - Visitor
It has not been repaired as of yet. Still looking for my best option. - Visitor
Check engine light flashing. Stops accelerating. Engine shakes and stalls out upon stopping. - Visitor
About two months ago, while driving, I noticed that the "Check Oil at next service station" light came on. I contacted my mechanic right away, and he asked me to bring my car in for him to check it. My mechanic informed me that my oil level was perfectly fine. At that time, he figured that something may have triggered the sensor. A week or two later, the same thing happened again. After the second false alarm, the "Check Engine Light" came on. This time my mechanic did a diagnostic test on my vehicle, and informed me that the gear on the Balance Shaft was worn prematurely.
I contacted Mercedes Corporate office and they instructed me to take my car into the dealership service department in order to receive a diagnostic test at my expense ($165.00 per hour). The results were: Recommendation to replace the Timing Chain Guide Pulley, and they also diagnosed Alternator noise.
The service representative at the dealership mentioned that this was his very first time ever seeing a car with a Timing Chain Guide Pulley issue. (My mechanic informed me that this was a huge lie; he assured me that they have had several other cars with this same issue, but they want to make me feel that my issue was very rare/random).
Later I contacted the Corporate Office again, and the Regional Case Manager that I spoke with informed me that there was no evidence that the Balance Shaft was worn prematurely. She said that there was no recall by engineers for this part. Based on my mileage, the part is not worn prematurely, according to the Service Director at the dealership.
Lastly, she mentioned that Merceds could only assist me with 10% of the cost for repairs at the dealership, or make a small donation toward the purchase of a new car or lease. - Visitor

sounds like a diesel engine... performs beautifully but sounds very bad. - Visitor
Trouble accelerating, have multiple codes. Only owned the car a year next week. Ran fine until a couple months after purchase. Now I have to try and trade this hunk of junk still owing payments!!!! I'm going back to Toyota! My Camry lasted 10+ years with minimal probs that were only due to age. Mercedes sucks for not recalling this model!!!! - Visitor
Te check engine light came on and flashed "speedtronic inoperable" came on the display flowed by ESP inoperable. The car then looses power and won't rev past 3800RPM. Have not been able to fix it yet but I'm hoping that a camshaft timing sensor or crankshaft sensor will fix it. Otherwise it may be the camshaft adjustor solenoid which only a MB dealer or trained tech should do and costs around 2-3,000 dollars to fix! - Visitor
