BMW 3series - Lost power to BMW M47 / M57 engine, why it happens.

Often your car does not have the same power as before, one of the causes may be this

My 320D e46 m47 old engine model 2001, is white smoke, burning diesel smell not oil, loss of power won’t go over 2/3rpm and is restricted, I’ve changed fuel filters I’ve changed fuel pump thinking many’s not getting enough fuel, I blanked egr and even cut out catalytic converter, turbo and injectors are perfect what could this be ?

greetings, please help, there is a bmw e91 2.0 d m47 163 hp in the car, it does not pull, that is, it does not turn on the turbine at all. egr car can't work, it chokes and chokes, I took off the vacuum hose that goes from the engine to the vacuum valve, there's vacuum already really good, but when I stop and take another hose with the valve that goes to egr, there's almost no vacuum, the same as someone cracked, but vacuum there is no, so if you can give some advice, there is no problem with the motor on the board, but it is on diagnostics, if you can give some advice, thanks in advance

My m47D20 e60, has turbo lag and it pulls at 2, 500/3, 000 RPM i checked the turbo and it was completely fine ..
DPF and CAT are out the only issue that i have when i read it is GLOW PLUGS 1/4 is alive..
Usually they have a role in the performance of the engine but im not so sure ..

Hi☺️ i have checked all my vacum lines and all seem to be good. But i get no vac to my turbo, some of the vac lines are a bit thin some places can that be the issue?

Hi just had an engine replaced and they used my old turbo which was working before. But for some reason the car doesn't have power going uphill and i don't even hear the turbo whistle sound like before. Someone said its vacuum lines but i dnt know were to begin. Bmw e46 320d

Hi my BMW is having black smoke and loss of power so I don't know what is the cause

Hello, my e39 530d has no power from 1800 rpm and 2500 rpm, from 2800 rpm it has a lot of power. Valve solenoid is ok and vacum hoses, what else need to check? Egr pipes ?

Mine has a I light blue smoke when being started n the Rev neddle sometimes is inconsistent.. No power specially when going on low gears. But sometimes the power just kicks in..

When I’m driving I’ll put my foot down in 2nd gear and turbo almost cuts off sometimes and I won’t be able to use it but other times will give me full or 80% power and be okay, any ideas what this could be?
