FAZ9488E, FAZ4160E and FAZ9484E: what to do

FAZ errors are replies from the Volkswagen server during an online GEKO session. They describe the state of the part or vehicle data, not a broken ODIS install.

FAZ9488E and FAZ9484E usually point to vehicle or component data that the server cannot match — check the VIN, part numbers and that the correct control unit is selected.

FAZ4160E is often resolved on the access side. Message us on WhatsApp with a screenshot and we will check it.
