Hello, a few days ago I bought a Saab 9-5 3.0TiD Built. 2002 (150tkm) to enjoy the great driving comfort of a 6-cylinder. Now the Saab continuously smokes and operates the accelerator pedal when accelerating (not when starting) black smoke from the exhaust system. I noticed this when looking into the rear-view mirror. In older articles I read about the following problems: – Fuel- Air mixture – Air mass meter (dreamed/defected) – Air filter – Test d it EGR (?)- Valve + can (?); should be 70% Felerquote of the Saab Diesel – vacuum hoses to turbocharger What do you recommend to me here? –
