There is a note/reference regarding block 067.
(Simulated exhaust gas temperature in the particulate filter)...for the 140-series DPFs.
respectively / or rather / that is to say
(calculated temperature) ... for the 170 series DPFs (e.g., BRD).
This is unreadable on the 75 model.
I believe the 67 is a calculated value, while the 75 is a measured value.
