Les causes fr\u00e9quentes incluent :<\/p>\n

    \n
  • Dommages ou dysfonctionnements du syst\u00e8me d\u2019admission<\/strong>, tels que des conduites us\u00e9es, fissur\u00e9es ou mal raccord\u00e9es.<\/li>\n
  • Filtres \u00e0 air inefficaces ou endommag\u00e9s<\/strong>, incapables de retenir correctement les particules et les d\u00e9bris avant qu\u2019ils n\u2019atteignent le turbocompresseur.<\/li>\n
  • R\u00e9sidus d\u2019une panne ant\u00e9rieure du turbocompresseur<\/strong>, pr\u00e9sents dans les conduits ou l\u2019\u00e9changeur.<\/li>\n
  • Contamination lors de la maintenance<\/strong> : m\u00eame de petits corps \u00e9trangers laiss\u00e9s accidentellement dans le syst\u00e8me peuvent causer des dommages importants une fois mis en mouvement.<\/li>\n<\/ul>\n
