Clear the codes and see what comes back, 18008/00668 are almost certainly a flat battery in the past. 17978 is a normal immobiliser code, an unrecognised key is the cause which again you just need to clear and see if it comes back. 17965 - search for sticking turbo vanes :) but again clear the codes. At the moment you have no idea whats new and what occured 5 years ago!
