Honda Accord (no more power)

Hello you! I hope you can help me! So I’m driving a Honda Accord 2.0 TDI BJ.1997 (105hp), he has about 180,000km on it and except that he has 2 holes in the exhaust (splipped), well these have apparently nothing to do with my problem. It’s like I don’t have a turbo anymore, so no matter which gear I turn, at approx. 2800-3000 revolutions I have absolutely no power any more, no matter how hard I push the accelerator, even with small n climbs drop the speed, I come on a straight track just to 120-130km/h, have no idea what that could be, do you know more? I thank you for every help and answer! Bye!
