Service bulletin LI32.30-P-079405

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Complaint Vehicle lifts and lowers again while driving. Cause Moisture may collect in the compressor of the air suspension over its lifetime, which can result in corrosion. Corrosion can result in reduced compressor performance or be deposited on the valve seats of the valve block and subsequently result in internal micro leakages. Remedy Update software for air suspension compressors as of 08/2022 or vehicles produced after 08/2020. Updated software removes moisture from the system by lifting and lowering the vehicle level maximum +/- 10 mm while driving. The process is not a cause for complaint, but rather corresponds to the current series production configuration. Replacement of parts is not necessary in this scenario.
