Coverage

What works on the Porsche Cayenne.

Chassis codes 958, 9YA. Only the 981 has been confirmed on a real car so far; the rest are built from the factory diagnostic data and tested against the built in simulator.

Chassis	Years	Connects via	What works today
958	2010 to 2018	OBDLink (Bluetooth)	Scan, fault codes, live data, coding
9YA	2018 on	ENET (Ethernet)	Scan, fault codes, live data

The 9YA (third generation Cayenne) uses automotive Ethernet (DoIP), so it needs an ENET adapter.

Try it on your Porsche Cayenne.

FlatDiag is in TestFlight beta. Request access for a beta invite, or explore the whole app first with the built in simulator, no car required.
