Hello newbie on here so hope I get things right. Have had the "restricted performance" msg come up in red on my 2010 10500mls xf as well. Stopped the car turned off waited for a minute started back up and all was well, but a day or two down the line and it comes back on. Taking it back to dealership to get sorted can anybody throw a light on the subject. Have a code reader so maybe that is the first step cheers an xf fan at the moment
