| Description of the problem | When starting up the vehicle make a terrible noise that last for 3-4 seconds before it goes away. The vehicle was verified by a mercedes technician and the diagnostics came back stating an issue with the "camshaft adjusters (internal fault)". I was told this condition will get worse and finally engine will stall and major damages will happen. Worst scenario could produce bent valves and will require a major engine overhaul with just 48,304 miles on it. Apparently, c250s are having this issue and customer are paying the consequences for a defective product. By the way, engine has been perfectly maintained with mobil 1 (ow-40) and original filter every 5,000 miles instead of the 10,000 miles interval recommended by the manufacturer. This condition could lead to a major failure while driving the vehicle that could end up into an accident. |
