FK3 error message PGM-SI / car no longer starts

Hello everyone. After my better half was shopping, now our diesel doesn’t start any more. On the display the error message appears: PGM-SI I called the workshop and had an absolutely capable 🙁 Man at the rib: There’s probably petrol in it… I had told him that last tanking is long ago, there’s still fuel in it, you can still drive about 200km. What can that be??? Now we have to see that the car comes into the workshop. t is so kulant that if they pick up the car, and it is not a guarantee (so false fuel: such nonsense!! or the battery) they would charge the costs! With my Ford I have mobility guarantee: there is always help to me and everywhere. Thanks for your quick advice!!! Ghiav6
