The xc90 Diesel is from April 24. Since autumn the display is constantly due maintenance, also in the app! The workshop then wanted to arrange a maintenance appointment for the end of January. Maintenance is included in the warranty package! The software errors with turn signal, lighting and maintenance, can not be found in the error memory and can not be eliminated. Maintenance can only take place after 12 months. Switching off the error message, would mean a risk, since then would not be pointed to the maintenance Rde! What can a false hint bring, which comes over months and must be pushed away again and again!
