2007 Mercedes-Benz C230 Engine cooling Problems

“Although I no longer have the vehicle as it was leased, around a year, a year and 4 months ago, my mercedes benz was making a weird noise from the engine as well so my check engine light had been on for weeks/months. When I took it into a mb dealership they had to first get my approval to take apart the engine to diagnose the problem, of course I said ok since it was a leased car. …”

“We have a 2007 mercedes benz C230 sport. Shortly after purchasing this vehicle used with 32000 miles on it we started having balance shaft problems. Since then we have had the balance shaft sensor, and magnets replaces along with the crank case sensor. The vehicles check engine light is still coming on and we are now being told the balance shaft solenoids need to be replaced as well.”

“The engine light came on asking me to go to the next gas station and check oil. When I took to the next day to a mechanic and upon a thorough diagnostics, I was told that the balance shaft (in take camshaft code 1208) and exhaust camshaft, code 1200 need to be replaced due to premature wear and faulty parts.”

“Vehicle seems to run fine but after a cold morning start the check engine light illuminated. After taking it to the dealership for diagnostics (totaling $105.00) it was revealed that the code rendering the balance shaft or possible bad sensor was the reason for the check engine light illuminating. The estimate cost for this repair is ranging from 5 to 6 grand. This is highly unacceptable for a vehicle with only 45,000 miles. …”

“Dtc 1208 code appears. Due to positioning of timing chain relative to crankshaft. Engine m272 caused by worn sprocket on the balance shaft of engine. Mercedes has repair kit available but has modified this problem on newer vehicles. This is a common occurrence on this engine, and should be part of a national recall compaign. The internet is full of complaints over this and I believe there is currently a class action law suit about this.”
