Emergency run, tell-tale annealing system lights, P0400 exhaust gas recirculation circuit, flow too large

Hello, I recently moved my Opel Vivaro for the first time. To the car: BJ 2003, 225000 km, Combi 9 seater, 1.9 cdti, 101 hp The engine did not pull at all during the ride, there was no power there. 1+2 gears were still relatively normal, from then on no acceleration at all. Maximum speed 80-90 km/h but also with 1 km acceleration path. 6 gears didn’t work at all. Had to drive about 40 km home with it, that was certainly not healthy. Speed was not limited, so he was already turning up to 3-4 thousand tours in low gear, but was not a force. Later I read out the error memory, the following error code: DTC: P1125 – charging pressure valve, low voltage – permanent I could not measure the voltage of the charging pressure valve itself, because it now no longer jumps in. Did anyone have a similar problem or can represent a careful remote diagnosis? Many thanks for the help!
