Hello All I'm new to this forum so hope I've posted this in the right section. I am a owner XF sportbrake 2.2 diesel 200 brake horsepower 2015 model. As I was driving to work yesterday a warning light came on the dash, a yellow triangle indicated I have a air suspension fault could any of the group members enlighten me on what this could be, also is it still safe to drive? I look forward to any reply.
