The driver is informed of the need for maintenance by the Flexible Service-intervallanzeige message, which is displayed for approximately five seconds after the ignition is switched on. Depending on the equipment, the message is output via the trip odometer or via the instrument cluster display.
If the maintenance time is approaching, then a message about the maintenance period is displayed after switching on the ignition or, respectively, after starting the engine in the following form:
Version 1: The trip meter displays the wrench symbol and the vehicle's mileage until the next service. After 10 seconds, the display changes: the clock symbol and the number of days until the next service appear.
Version 2: The message SERVICE IN 2000 km oder 40 Tagen appears in the instrument cluster display (TO in 2000 km or 40 days). After 20 seconds, the message about the upcoming maintenance goes out.
When the maintenance period calculated by the control unit comes, a gong sounds and the wrench symbol flashes, and the display accordingly shows the message SERVICE! Maintenance must be carried out as soon as possible.
Note: overdue maintenance is displayed with a sign «-» before the mileage or number of days.
After maintenance, the maintenance interval indicator must be set to its original position using the workshop diagnostic equipment.
If the engine of a car with a Longlife-Service system was filled with engine oil that was not intended for long-term operation as part of a service or repair, then the maintenance interval indicator must be reset from «flexibel» (not regulated) on «fest» (regulated). In this case, the car is serviced every 15,000 km or 12 months. Resetting the service interval indicator is done using the setting buttons located at the instrument cluster.
Attention: To save maintenance with an unregulated interval, the interval indicator must be set to its original position using the diagnostic equipment of the VW concern (at the service station).
Note: The workshop additionally reads the fault codes from the electronic control units for the engine, ABS, airbag and anti-theft system with the help of a reader for every service. Therefore, it makes sense to visit a service station after a certain mileage, even if the maintenance is performed independently. Reading of codes of malfunctions is carried out through a diagnostic socket of the car. In this case, at the request of the car owner, the maintenance interval indicator can also be set to its original state.
