Were you doing any work on the car recently?, I was messing about with fuses a few weeks back, removed and tested every fuse to try to fix a problem, but put one back in the wrong slot and got en engine start start system fault, the car started and drove fine, but I had the warning every time I started it. Found out I had the fuse for the steering lock put back into an empty slot and actual slot left empty, swapped back and problem solved, probably not the same as your problem, just check that fuse, just in case its on the passenger side

Nevermind, I managed to dig out the fault codes I was getting, it's totally different
