Lowering with VCDS: Electronic Ride Height Calibration
dieselschrauber Post08-09-2006, 12:39  
The following instructions explain how to calibrate the "zero position" of the suspension control unit and adjust the vehicle height using VCDS. This applies to the VW Phaeton (Type 3D), VW Touareg (Type 7L), Audi A6 (Type 4F), Audi A8 (Type 4E), Audi Allroad (Type 4B), and Audi Q7 (Type 4L).

Necessary equipment:
The following conditions must be met during the modification procedure:
  • Set the transmission to 'Park' or 'Neutral'.
  • Start the engine and let it run.
  • All doors must remain closed.
Since opening the doors will interrupt the procedure through the control unit, it is recommended to operate the laptop from outside the vehicle.

The factory settings for the vehicles are...

    Audi A6 (4F) standard suspension: xxx mm (front) and xxx mm (rear). Feedback is welcome.
    Audi A6 (4F) sport suspension: xxx mm (front) and xxx mm (rear). Feedback welcome.

    Audi A8 (4E) standard suspension: 416 mm (front) and 398 mm (rear).
    Audi A8 (4E) sport suspension: 396 mm (front) and 378 mm (rear).

    Audi Q7 (4L) standard suspension: 465 mm (front) and 449 mm (rear).

    Audi Allroad (4B) standard suspension: xxx mm (front) and xxx mm (rear). Feedback welcome.

    VW Phaeton (for markets outside Europe): 407 mm (front) and 401 mm (rear).
    VW Phaeton North American version: 417 mm (front) and 411 mm (rear).

    VW Touareg (7L) standard suspension height: 497 mm (front) and 502 mm (rear).
    VW Touareg (7L) Off-road ground clearance: 488 mm (front) and 498 mm (rear).

Procedure:

  • Steuergeräteadresse 34 (Fahrwerk) auswählen.
  • Erweiterter Login / Security Access auswählen.
  • Zugangsschlüssel 31564 eingeben.
  • Adaption/Anpassung auswählen.

  • Kanal 01 auswählen (Rad vorne links), 'Lesen' drücken und warten. Das Fahrzeug bewegt sich bis zu 2 Minuten auf und ab um schließlich in einer Position zu verharren.
  • Nun mit dem Meterstab die Entfernung zwischen Zentrum der Radnabe und unterer Kante des Radkastens messen. Den Meßwert [mm] als neuen Wert in VCDS eingeben und abspeichern.
  • Dasselbe für die übrigen 3 Räder in den Kanälen 02 (vorne rechts), 03 (hinten links) und 04 (hinten rechts) durchführen.
  • Schließlich im Kanal 05 durch Speichern des neuen Wertes '01' die Einstellungen bestätigen.

Jetzt ist die Fahrwerkshöhe kalibriert. Gibt man statt der gemessenen Werte z.B. 15mm größere Werte an, wird sich die Fahrposition des Autos 15mm tiefer einstellen. Für For smaller values, the opposite is true.
To adjust the vehicle height, you can also use the control unit coding to specify the desired change in height (not available for Audi Allroad). During calibration, you enter the actual measured values. Our VCDS diagnostic systems include a label file that explains which coding values correspond to which changes in height.
