Ash Content Incorrect? What Next?

Hi.

According to A012 in the label file, I should have 6.186426 g of ash.
Approximately 20,000 km * 6.77 liters / 100 km * 0.004569 (g/liter)

My MSTG believes in 5.25g, which is almost 20% less.

Could it be that the ash mass changed during the software update from version 0420 to 1184?
Back then, something definitely strange happened because the DPF light came on 90 km after the update.

The deletion must not have happened, because the update was installed when the car had approximately 15,000 km, and now it has approximately 20,000 km.
