The camshaft solenoid was replaced to fix check engine light with fault code P0024. Check engine light reappeared after a month with same fault code. I was advised that I now need to replace the timing chain, tensioners, and guides. According to the technician, the timing chain may have stretched a bit because of wear and tear. Which is causing the check engine light to reappear.

when I push the round button in the center to select language and radio or cd; it doesn't do anything...none of the buttons do anything. can I take the console cover off?
