XC 90 II D5 does not start

Hello, since today’s noon the XC 90 doesn’t speak to any more. We have placed it in a parking lot, are back after about an hour and he didn’t let himself start. That means foot on the brake pedal, ignition is on, all indicator lights on the dashboard light, no error message but the turning of the start button to the right remains without any reaction, it does nothing. The car can be started when locked but over the Volvo app remotely. However, as soon as I put myself in the car, the brake kicks and turns the start button to get out of the long-distance start into the regular run, the engine goes out and, as described above, can’t be started. 10 key (clamping battery) I tried twice, no change. fuses all seem OK. Does anyone have an idea? Just stand on vacation somewhere in Croatia and a towler would have to drag the car pretty far to a Volvo dealer…
