Consider how you can find the CAN stop mileage filters installed in the car now or previously. In the car that came in the trade-in was declared mileage of 15 000 km. I am using BMW eXtratool software on Android.
Select BODY - Check mileage blockers.

Vehicle mileage at last regeneration - mileage at last regeneration of particulate filter 29429,48 km.
We can immediately see that the mileage at last regeneration of the particulate filter is higher than the declared mileage. Information about the mileage at regeneration is always recorded real, which is received by the engine control unit from the control unit of the stabilization system. The whole point is that the transmission of this data is carried out via the Flexray data bus, and there are simply no blockers on this bus.
The engine control unit saves information about the mileage of the last 5 regenerations of the particulate matter. As a rule, we are only interested in the mileage of the last regeneration.

Operation time counter - engine control unit operation hour counter 676.30 hours.
DDE/DME unit operation time counter or engine hours. By comparing engine hours with transmission hours and transfer case control unit hours (for all-wheel drive cars), you can roughly estimate total mileage (multiply hours by average speed) or find a replaced control unit. In this car motor hours are different from the transfer case motor hours 879,72 and as it turned out later in the car is not a native engine control unit, and its clone to make a chip on the clone. Somehow there is a mistaken opinion that if you make a chip on the clone and on the native block only to come to the dealer for maintenance - they will not find that the car on the chip. As a rule in such a situation comes the answer from technical support and why the car has an average speed of 1105 km/h The mileage is high and the hours are not enough.

Total distance covered since first start - total distance covered since the machine was first started at the factory 30191.85 km.
This indicator shows the actual mileage of the machine at the time of the Extratool survey. It cannot be corrected with filters for the same reason - the use of the Flexray tire.

Last regeneration - last regeneration 29429,48 km.
All the same as in Vehicle mileage at last regeneration - mileage at last regeneration of particulate filter 29429,48 km.

Last regeneration time - motor-hours at last regeneration of particulate filter 663,53 hrs.
This parameter displays the hour counter of the control unit during the last regeneration of the particulate filter.

Consumed after regeneration - fuel consumption after regeneration 38.1 liters.
Shows how much fuel was consumed after the last regeneration of the particulate filter.

Consumed after DPF change - total fuel consumption after particulate filter change 1963,10 liters.
Another indicator that cannot be corrected by different cheats. It shows how much fuel is consumed after particulate filter change. For a car from the factory where there has been no particulate filter replacement it shows the total amount of fuel consumed from the moment of the first start. After the particulate filter replacement is performed, the counter will be reset to zero.
For this car we divide the total consumption/by the estimated average consumption of a similar car in your city * 100 = 30 000.
As we see almost perfectly coincides with the parameter Total distance covered since first start - total mileage since the first start of the car at the factory 30191,85 km.


Amount of fuel passed through the injectors - amount of fuel passed through the injectors 795,00 liters.
This parameter is always less than Consumed after DPF change - total fuel consumption after particulate filter change 1963,10 liters.
This parameter probably indicates fuel consumption through the injector but in some special mode of operation (preparation for regeneration plus regeneration itself or something else) unfortunately it was not possible to understand exactly, but considering that it does not have any usefulness for my needs - I did not really want to understand it.

Average consumption of the vehicle since last DPF replacement - average fuel consumption after particulate filter replacement is 6.60 liters per 100 km.
For a car from the factory where there has been no particulate filter replacement it shows the average consumption of the spent fuel from the moment of the first start. After the particulate filter replacement the counter will be reset to zero. It is useful to compare it with the average consumption from the instrument cluster. As a rule, for a car with stop mileage the difference is very significant. In this particular case, the engine control unit shows 6.6 liters and the instrument cluster (KOMBI:KOMBSP18) 19.73 liters.

KOMBI:KOMBSP18 is the version of the instrument cluster control unit and the average consumption is 19.73 liters/100 km.
Average fuel consumption on the instrument cluster. For cars with stop mileage is very different from the real fuel consumption.

LMV:LMV_G11 - version of transfer case control unit and operating time 879.72 hours.
The operating hours of the transfer case should be more or less the same with other control units. If there is a difference, it is a reason to discuss with the seller whether the unit may have been replaced due to breakage or some manipulation.

In the next part I will tell about the subtleties of checking gasoline cars.
