A recent patch (v1.11) for Dirt Rally has meant that the Thrustmaster wheel is no longer compatible with the game. However, Codemasters have said that they are working on fixing the issue.
Community manager CristinaMC wrote this on the game's online forum: "Hi all, just to let you know we're aware of the issue with Thrustmaster wheels on PS4, and we're looking into a fix this - will keep you posted on our progress. Thanks for your feedback - it's really appreciated, and please be reassured that we're cracking on with fixing this."
Hopefully Codemasters will fix it sooner rather than later, because as our review indicates, Dirt Rally is an excellent game and fans will no doubt want to get back behind the wheel as soon as possible.
