Replacing turbo solenoid with manual boost

chrisdk223 · 10-16-2021, 03:27 PM

Hi! I have a BMW X1.
I noticed the engine malfunction light turned on. I opened the hood and there was no solenoid. I was going to simply add one but there was no electric wire to plug in. I just found i can bypass this whole process by connecting a hose that enter the engine cover into a manual booster then that to the wastegate.
I found the line that goes from actuator back to air pump.
But cant figure out how to connect the manual boost to the wastegate.
Any help? Please!

First thing: scan the car and find out why your check engine light is on.

Second, why are you trying to add a manual boost controller? This will cause the check engine light to be on all the time.

It seems like there are 2 types of configurations. I got lost.
There is a version that comes with a solenoid and a non electric wastegate.
And there is a version that is connected directed to an electric actuator.
I just realized that a part of it rusts and is recalled. Seems like a super easy repair now!
I still wonder, what about that second opening on the engine cover... should it be closed since not connected to solenoid? or open?
