hi
when i do the self code test im getting error P0014 B Camshaft Position - Timing Over-Advanced or System Performance.
does anyone know what this means? can i fix it myself or does it need to be vx?
cars still in warranty but i dont rate my local and the next nearest one is far away
also anyone one know if its a known problem if your getting rattling from the rear of the car, it sounds like its inside somewhere in the boot area but its hard to trace cos it only does it now and again

any help will be appricated
thanks
