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.
