Buying Tips for 2012 Saab 9-5 NG

  • Check the LED light bar across the boot lid; water ingress frequently causes sections to fail, and replacements are virtually unobtainable.
  • Verify the operation of the Head-Up Display (HUD) and the digital speedometer, as the electronics can be glitchy.
  • Ensure the Haldex 4WD system (XWD models) has been serviced regularly, as neglected fluid changes lead to pump failure.
  • Inspect the interior trim for damage; unique plastic pieces are no longer manufactured and must be sourced used.
  • On the 2.0 TTiD diesel, check for DPF blockages and ensure the twin turbos spool smoothly without excessive smoke.
  • Confirm the car comes with two working keys, as programming new keys requires specialist software (Tech2/MDI) that few garages possess.
