Porsche Cayenne diagnostics & coding.
FlatDiag reads and clears fault codes across your Cayenne 958 in plain English, with live data and coding, and registers a new battery on gateway version A5 and later. The newer 9YA is not yet supported.
What works on the Porsche Cayenne.
Chassis codes 958, 9YA, 955 and 957 (the 9YA, 955 and 957 are in development; the 9YA is not yet supported with the OBDLink CX). 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 app's demo car.
| Chassis | Years | Supported functions |
|---|---|---|
| 958 | 2010 to 2018 | Scan, fault codes, live data, coding, battery registration (gateway A5 or later) |

The 9YA (third generation Cayenne) is in development and not yet supported with the OBDLink CX; from model year 2024 it uses Porsche's online security token and is not supported. The first generation Cayenne (955 and 957) is in development, for scan and fault codes.
