Service bulletins for the 2016 Porsche Cayenne

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.

122-W6E3D-032017-10-25. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. No cooling in the passenger compartment. NOTE: A low state of charge of the High Voltage Battery can cause the AC to be deactivated until the state of charge increases to an adequate level. Customers who do not plug their vehicle in on a regular basis may have this issue. There are two shut off valves in the refrigeration circuit. 1. The chiller shut off valve is normally open and requires 12V be applied to it from the AC control unit to close it. This would stop cooling of the high voltage battery. a. Power and ground from the AC CU can be checked at the connector of the valve. 2. The evaporator shut off valve is normally closed and requires 12V to be applied to it, via a relay, in order for the valve to open and provide cooling to the passenger compartment. a. The evaporator shut off valve can be diagnosed easily by removing the relay and jumping the load contacts of the relay to see if power makes it to the valve. Power at the valve opens it and the evaporator gets cold with normal AC operation. b. The relay winding circuit can be tested for power and ground from the AC CU.

Fitting a new protective ring on the front output drive (sometimes also referred to as "dust boot"), ? Fitting a new vent connection (breather adapter) ? Retrofitting a vent line in the vehicle.

AG02 Stop Sale Campaign/Recall Campaign - Checking Circlip on Bearing Bracket for Pedals Internal tests have shown that a circlip on the bearing bracket for the pedals may have become detached from its locking position as a result of preassembly processes carried out by a supplier. In this case, the bearing pin for the pedals will no longer be secured axially in the bearing bracket and can come out of one of the two bearings over the service life. If the bearing pin is mounted on one side only, brake pedal actuation will be impaired.
