Hello. I have a problem with my Skoda Octavia II1.6 FSI. The engine light came on, I went to the mechanic and after connecting the computer, Error P00016 appeared. Camshaft and crankshaft position sensor. After clearing the error, this error still appears. As far as I know, the reason could be a loose timing chain. Does anyone have a diagram or film how to replace this timing? Unless that's another reason. Please help.
