V50 has no more power and only turns up to 3000 u/min

Hello everybody, today on the way home from work I noticed that my V50 (2008er 1.6D slightly more than 100000km) has much less power and only turns up to max. 3000 u/min. Otherwise the engine runs quietly. There is no warning light. Since the workshop has now closed: Does anyone have any idea what that can be? It almost seems to me as if the turbo is no longer running? Can this be possible? Can I drive to work with it tomorrow (max. 10km)? Would you be very grateful for the answers!
