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

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?

@TheOnlyRaceEngineer 5 ай бұрын

well in that case, the usual suspect is the pressure converter (solenoid valve) which gets stuck and cannot regulate the vacuum correctly. In case you have already changed that, simple do a smoke test your main vacuum line. i did it recently using a castronica pocket smoke machine. just 35 euros.

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

usually those vacuum hoses crack and they all need to be replaced approx. 3 meters, after the electric vacuum valve from the egr you only have vacuum at some moments not always, make sure that vacuum tank on the vacuum line of the turbine is not broken .

Salut, furtun de vacuum poti gasi la orice magazin de piese auto, ei il vand ca fiind furtun combustibil, iti recomand GATES sau Rapro (poti sa incerci si original este undeva la 100 lei m, si ai nevoie cam de 3 m), cu camasa textila pe exterior. dimensiunea este de 3.2mm la interior si 7mm la exterior. Daca te pot ajuta cu altceva imi poti trimite un mesaj pe whatapp la numarul 0766 52 27 67. Drumuri bune iti doresc.

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 ?

@user-midnightmachanic Жыл бұрын

Hi am having same issue as you have u fixed it yet not even got a code coming up

@TheOnlyRaceEngineer 7 ай бұрын

when you blanked egr, did you also program it out from the ECU? if not then you should do that as well, otherwise you will also get white smoke. I currently have the same problem and I am getting charge-air pressure deviation of more than 85 mbar through the MAP sensor which I checked through DIS software. I think the problem is a vacuum leak . I will check them thoroughly this weekend and let you know if it worked. I have been diagnosing this issue for a few months and now I know that before ordering new sensors, I should first check the simple things as the video suggests

@shahrose2383 5 ай бұрын

check your air filter , if you got a small aftermarket come filter it can cause that, gets stuck at like 3k rpm & causes 3ff0

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

Yes, there can be a problem with the vacuum hoses, pay attention to the gas purifier.

I have the same symptoms. Changed glow plugs as they had a fault stored. Dpf is showing as blocked but even with it removed I have the same lack of power. Turbo seems ok, it was replaced not long ago by the last owner. I have "charge pressure deviation" fault stored.

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 ?

@JHAMS-007-car-repair Жыл бұрын

I don't know the configuration of these engines, make sure there are no vacuum losses, especially at the vacuum compensator. There may still be problems with the turbine's vacuum control actuators.
