Symptom:
When the original display is removed the long press on the trip computer button does not reset the consumption counters.
Technical:
The original display sends a status message every ~500 ms (5E 4C 20 1E 8A 50). When the trip button is held down for 2 seconds this message is replaced by 5E 4C A0 1E 30 2E. This will command the BSI to reset the counters.
Unfortunately the first attempt to implement this shows that this message somehow clashes with the query for the trip data.
