OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.

• no PID to retieve exact data for oil pressure

• Turbo boost pressure -> request = 22195A -> equation = (A*256+B)-32768 (should be in mBar) -> OBD Header = DA10F1

• Air temperature (boost/manifold): -> request = 221935 -> equation = (((A256)+B)0.02)-40 -> OBD Header = DA10F1

• Engine oil temperature: -> request = 221302 -> equation = (((A256)+B)0.02)-40 -> OBD Header = DA10F1

• UniAir oil temperature: -> request = 22198E -> equation = (((A256)+B)0.02)-40 -> OBD Header = DA10F1

• Engine coolant temperature (°C): -> request = 221003 -> equation = (((A256)+B)0.02)-40 -> OBD Header = DA10F1

---

• DPF clogging: -> PID = 2218E4 -> equation = ((A256)+B)(1000/65535) -> OBD Header = DA10F1

• DPF exhaust gas temperature: -> PID = 2218DE -> equation = (((A256)+B)0.02)-40 -> OBD Header = DA10F1

• DPF regeneration process: -> PID = 22380B -> equation = ((A256)+B)(100/65535) -> OBD Header = DA10F1

• Distance covered from last DPF regeneration: -> PID = 223807 -> equation = ((A65536)+(B256)+C)*0.1 -> OBD Header = DA10F1

• Total DPF regenerations: -> request = 2218A4 -> equation = (A*256)+B -> OBD Header = DA10F1
