Turbo or crack in pipe... Can be mass air sensor. Pressure sensor or air intake sensor... But mostly... The turbo. So check intake pipes... Vacuum pipes... Sensors... And last... Turbo.... If you unplug the mass air flow sensor... It will drive and you won't get the engine malfunction error
.. But this is not a fix... Just prevents the annoying message. And eml light will appear.
