Hello!

I need some help here. My CEL came on yesterday. I took it to auto zone and it gave code P022 and gave me 3 possible things that could be wrong; blocked oil passage, timing belt jumped teeth or camshaft actuator. Mercedes Benz wants $165 just to get it checked, which is too much. My car is 2007 MB C230 sport, with 67K miles. Any help or suggestions will be greatly appreciated.


Thanks!
