Control unit faulty: Notes
WARNING: This page is about a different car, the 2006 Porsche Cayenne, 2005 Porsche Cayenne, 2004 Porsche Cayenne, and 2003 Porsche Cayenne. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Only if the fault code 0003 'Control unit faulty' appears in the Porsche System Tester II No. 9588 in conjunction with the red warning in the instrument cluster 'Air spring warning', can a fault in the control unit be assumed.
- If no red warning is present in the instrument cluster or if the logo 'Air spring warning' is not displayed, then the fault can be erased without troubleshooting.
