F39 Impossible OIL service reset

[slavka91]

Hello , BMW f39 car arrived from US to EU without DME ecu . the ecu was replaced to EUROPEAN (part number same) . Did reflash and code by VO , Engine starts and runs fine . The problem is impossible to reset oil service (screen shows --/--/--) (before reflash was the same). Checked wiring on oil level sensor in oil pan , and checked sensor for any damage. Any ideas how to sort it out ?
