Like you said, the service interval (time/distance) can be reset manually by anyone.
The procedure can be found on the forum.
BUT
The oil service interval instead it's a procedure that only a dedicate tester (dealer's or other's) can perform.
It implies resetting some parameters in both engine ECU and Central Junction Box.
If you know what to do, i.e. sending commands over CAN bus, it's like this:
For engine ECU (CAN ID: 0x7E0):
1. Switch the engine ECU to extended diagnostic session (10 03)
2. Run the routine with ID 0x4024 (Oil change reset) on engine ECU (31 01 40 24)
3. Close engine ECU extended session (10 01)
For CJB (CAN ID: 0x726):
1. Switch the CJB to extended diagnostic session (10 03)
2. Authorize yourself on CJB by seed/key pair in order to gain write access (27 03 ...) (27 04 ...)
3. Write 0x0000 for PID 0x0528 (Oil wear backup) (2E 05 28 00 00)
4. Close CJB's extended session (10 01)
That's all.
