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. The objects are those of the MQB instrument cluster; on the 8Y cluster they are checked by reading — if one is missing, a3c refuses before writing. The interval is not changed: the cluster calculates the next due date from its own settings. Unit 17 on MQB Evo is SFD-protected — a token for unit 17 is needed. Roll back by writing the object backups from history.
