I was driving on the motorway earlier today, using cruise control. After about an hour a message "Check PCS System" came up on the instrument display with the red warning triangle and the cruise control stopped working. I tried to reset it, but I couldn't and instead got a different message "Check Cruise System". After a few seconds this message went off and the first message came back and now stays on permanently.
Any ideas? I checked the handbook but I wasn't much use. Is this something I can reset myself or does it mean a trip to the dealer? The car is still under waranty.
