Thanks so much for sharing your question with us, and welcome to the Automatic community. Your vehicle should work with Automatic just fine, provided you're using a 2nd generation adapter. While we plan on rolling out support for diesel vehicles on our 1st generation adapters, they will only work with vehicles from 2006 – you can read all about diesel support in this FAQ. :)
Please let me know if you have any other questions, we're always happy to help!
