BMW lost power

[erikuonas 55]

Hello, I bought this car 4 months ago, no problems until 3 days ago. I got into the car after a cold night, the engine started like usual but it was very slow when accelerating, barely any power at all until the turbo kicks in, roughly above 1500rpm (when the turbo starts to work) although still less powerful then before, the power is better up until 3000rpm, then the engine losses power yet again (not accelerating at all in 5th or 6th gear) . When the engine heats up the power is way better but still less powerful than it should be. I also noticed that I seem to brake faster when coasting in gear than before. Haven't noticed any smoke or any wierd noises. BMW 525d 2006 e61 125000miles. Thank you.

Loss of power and more coast down deceleration point to a blockage in your exhaust system. I'm not knowledgeable on BMW diesels, but I would be looking to the exhaust system.
