Hi guys, I'm hoping this is where I will finally find an answer to my problem. About 6 months ago I had to replace the timing chain on my car (C220 CDI W204). After the timing chain was replaced I imminently experienced loss of power and very poor MPG. The car takes a while for it to reach about 2000 rpm, way longer than it. I took it back to where I had the timing chain replaced they assured me that is not whats causing the lack of power. I have done checks on the car as some mechanics told me its the DPF which I had cleaned before and after the loss of power occurred. I also had the turbo checked; both of which are working fine and are not the cause of this problem. What do you guys think is causing this issue? Any suggestions will appreciated.
