Complaint "Vehicle Leaning to One side - Leveling System (I-no. 1BK) Issue" (90/12)
Model year:
as of 2011
Vehicle Type:
All Cayenne models (92A)
Equipment:
Leveling system (I-no. 1BK)
Concerns:
Leveling system
Information:
Complaint "Vehicle leaning to one side or Leveling system issue".
At cold outside temperatures, condensed water can freeze in the leveling system and cause problems.
Information In the event of one of the following complaints:
^ Vehicle leaning to one side,
^ Leveling system function not available or
^ Warning message "Chassis system failure" in the instrument cluster
please check the following point before starting any other work:
--> If the problem occurred at cold outside temperatures (well below freezing point/temperature range < ?5° C/5° F),
the vehicle should be left parked outside (cold outside temperatures required) overnight.
The next day, when the leveling system is cold, check whether the symptom is still present or can be repeated.
Work Procedure:
1. The symptom is still present:
--> Park the vehicle overnight again in a warm area (> 0° C/32° F).
2. After leaving the vehicle overnight, check the function of the system again: If, after carrying out this procedure, the symptom:
^ is no longer present, continue with step 4,
^ is still present, continue with step 3
3. Replace air spring on the affected spring strut:
3.1 Remove the spring struts affected by the problem (e.g. "Front left of vehicle lying to one side/too low" --> front left spring strut), see -->

3.2 Disassemble the removed spring strut, clean it and above all, assemble it again using new air springs and new seals, see --> 433037 Disassembling and assembling front spring strut and --> 432537 Disassembling and assembling rear spring strut (air springs).
3.3 Re-install spring strut, see --> 433019 Removing and installing front spring strut (steel springs) - section on "Installing" and --> 432519 Removing and installing rear spring strut (air springs) - section on "Installing".
3.4 --> Re-fill the system, see --> 4301IN Bleeding and filling the levelling system.
End of remedial action.
4. Carry out further fault finding using the following documents:
--> Symptom-based repair instructions in --> 431555 Eliminating symptoms on chassis: Replacing compressor for levelling system (for I-no. 350/351) (Levelling system/PASM defective/SY0211) and
--> --> 430149 Troubleshooting the levelling system.
End of remedial action.
