ThanksI'm running the latest Ross-Tech version, 15.7.1.0; it showed a few extra values:
Mode 9 : Calibration Identification
Type 02 - VIN : 3VWPL71K89M280210 (Address E8)
Type 04 - Calibration ID : 03L997016P (Address E8) <---same
Type 04 - Calibration ID : 02E300052 1985 (Address E9)
Type 06 - Calibration Verification Number : 12FFD699 (Address E8) <---same
Type 06 - Calibration Verification Number : 00006218 (Address E9)
Type 0A - Controller Name : ECM-Engine Control (Address E8)
Type 0A - Controller Name : TCM-TransmisCtrl (Address E9)
Type 0B - In-use performance tracking :
OBD Monitoring Conditions Encountered count : 2413
Ignition cycle count : 6133
Conditions completion count / Specificied conditions encountered count
NMHC Catalyst : 305 / 146
NOx/SCR Catalyst : 0 / 0
NOx Adsorber : 963 / 2413
PM Filter : 0 / 0
Exhaust Gas Sensor : 0 / 0
EGR and/or VVT : 2703 / 2411
Boost Pressure : 0 / 0
Fuel : 0 / 0
But it's noteworthy that the calibration ID and verification numbers are identical. Still not entirely sure just what they represent. In many embedded systems 'calibration' is a per-unit concept, and the values calibrated generally vary from unit to unit. Perhaps it has a bit-mapped meaning as opposed to a data integrity checksum one.
I'd be interested in these values for some TDIs that have 100K, 50K, and maybe 5K miles.
looks like you got responses from the DSG as well as engine controllers. E9=DSG E8=engine
I would also like to see what changes, if any, happen on an individual car with the emissions (or other) ECU software update. the update software has to verify the previous version. would make sense if this information is also available via the standard OBD emissions query.
