1. Connect your OBD2 scanner to the vehicle (OBD port under dashboard).
2. Turn ignition ON (engine OFF).
3. Navigate in the scanner to:
   • Service / Maintenance
   • → Oil Service Reset
4. Select:
   • With tester
5. Confirm oil reset:
   • Option 1/F1/YES

1. Turn ignition to OFF (position 0)
2. Press and hold the left button on the instrument cluster (trip reset)
3. While holding the button, turn ignition to:
   • Position 1 (ignition ON)
4. Keep holding the button for about 5 seconds until you see:
   • Oil Service / Inspection + remaining distance
5. Release the button

6. Press and hold the button again
7. After ~5 seconds, you should see:
   • “Reset” flashing on the display

👉 If “Reset” does NOT appear:

• The service interval has not reached the minimum threshold → reset is not allowed

8. When “Reset” is flashing:
   • Release the button
   • Press and release it again briefly
9. The new service interval will be displayed

• ❗ Reset is only possible if the service interval condition is met
• ❗ Timing matters — if you miss it, just repeat the process
• ❗ Scanner method is more reliable, especially on problematic vehicles

• On BMW E46, this is a very simple procedure → scanner is not required
• Scanner is useful if you:
  • Work on multiple vehicles
  • Need additional service functions or diagnostics
