Summary
There is increased friction in the air spring compressor valves at temperatures below ?13° F (?25° C). This can result in a situation in which the maximum control current is not sufficient to actuate the valves. As a result, a warning message will be displayed in the instrument cluster and Porsche Active Suspension Management (PASM) will stop working temporarily. Re-program PASM control unit using the PIWIS Tester with software version 33.010.030 (PIWIS Tester 3) or version 17.100.030 (PIWIS Tester II) or a higher software version installed.
