A relative of mine has recently bought a Saab 9-5 3.0 diesel and he is experiencing a severe misfire at all revs. I havent much information on the problem, only that he has had a service done and the oil was topped up (not changed). The fault wasnt present when picked up or the return journey home and that was a good run (Perth to Derby). The car has done a fair few miles (150,000) but I'm told the mechanical and exterior condition do not give that impression.
I have read that these engines need good oil and also can suffer from injector and fuel pump issues. I believe these are common rail systems and maybe suffer from carp in fuel lines? I was also noted that if you run these low on fuel it can exhibit a similar problem.
Have you guys any ideas that I can suggest he looks at?
