      \n
    • \n

      Folose\u0219te un OBD2 scanner compatibil Opel<\/strong> (ex: ELM327, Autel, Launch)<\/p>\n<\/li>\n

    • \n

      Conecteaz\u0103-l la portul OBD<\/p>\n<\/li>\n

    • \n

        NU \u00eentotdeauna. \u0218tergerea codurilor f\u0103r\u0103 a repara cauza real\u0103 va duce la reapari\u021bia erorii \u0219i, \u00een timp, la defecte mai grave. Diagrama corect\u0103 e:<\/strong>
