What changes
Unit 17: objects 2243 and 2244 are zeroed completely, 2232 byte 0 = 00. The oil change reminder starts counting again.
Details
The same as the reset in the service menu after an oil change. MQB cluster objects; Odyx checks them by reading — if one is missing it refuses before writing. The interval does not change: the cluster computes the next date from its own settings. From model year 2021 the cluster may be SFD-protected; then it refuses to write without a token. Rollback: write the object backups from the history.
