# Service bulletin 122\-F7A7X\-10

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.

- Type: Service bulletin
- NHTSA id: 10122094
- Published by NHTSA: 2017\-11\-08

## NHTSA's summary

The rear lid closes at a higher speed particularly at cold temperatures. The signal from the microswitch in the lid lock is too short and cannot be read out clearly by the control unit software.

Situation: Cayenne Diesel vehicles were equipped with undisclosed Auxiliary Emission Control Devices which are not permitted by emissions regulations. Action Required: Install updated engine control module \(DME\) software and transmission control module \(Tiptronic\) software to bring affected vehicles into regulatory compliance.
- [122\-J4H9M\-12](/bulletins/10125210.md), 2017-12-14, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; ENGINE. Situation: Cayenne Diesel vehicles were equipped with undisclosed Auxiliary Emission Control Devices which are not permitted by emissions regulations. Action Required: Install updated engine control module \(DME\) software, transmission control module \(Tiptronic\) software and hardware to bring affected vehicles into regulatory compliance.
- [122\-Q4E3L\-10](/bulletins/10122087.md), 2017-11-08, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE. 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.
- [122\-V6K2R\-06](/bulletins/10117494.md), 2017-09-14, Service bulletin: ENGINE AND ENGINE COOLING:COOLING SYSTEM; ELECTRICAL SYSTEM:SOFTWARE. Concerns: DME control unit Information: This is to inform you of a voluntary Workshop Campaign on the above\-mentioned vehicles. With the previous software for controlling the cooling\-air flaps for demand\-controlled regulation of engine cooling, there is a possibility that the cooling\-air flaps will remain closed at speeds of over 124 mph 200 km/h\) on the affected vehicles. If this high speed is maintained, the cooling\-air flaps can no longer be opened when additional cooling air is required due to the air force acting on the vanes. In this case, cooling performance can be reduced and as a result, the warning messages "Engine too hot, Park vehicle to cool down" and "Oil temperature too high" can be displayed in the instrument cluster.
