Seat Leon OBD-II support
Model years 1999 to 2026CombustionOnboarded
78,851 miles driven with Pelican by 87 drivers
The OBDb lists 10 parameters for the Seat Leon, read from 2 control modules. Real responses from Seat Leon cars confirm 6 of them. Drivers have tested model years 2012, 2015 to 2021, 2023, 2025.
Support by model year
A solid mark means a real response confirmed the parameter. A light mark means the car's signalset reads it but no response has confirmed it yet.
Parameters
The parameters of the Seat Leon, by group. These are the commands that Seat added, and the SAE J1979 standard parameters that real cars confirm. Open a group to see each parameter, how Pelican decodes it, and the model years that real cars confirm.
