    Is this? I have 0 resistance.
    RPM and 5v is ok.

    I leave a video, listen to the activation of the valve, only when I go up or down, at a few rpm.

    definitely you shouldn't have 0 ohms there. I don't have a module here to test but maybe someone can give more clues to it

    I'm waiting for confirmation from a partner.
    Is this a retention mosfet? Through the R of 1.8 ohms?

    Change the fet and now I have code U0105.
    5v is correct.

    I did not have that error before.

    May it be the actual solenoid or the spring is broken inside?

    Hi!
    I have in garage 2.5 tdi and vp44 transistor is blown away so i put new transistor irlr 3110 and car start but error 01268 and 3k rpm.
    Have done some research for transistors that we have use and years are passing but we don't know are they really good substitution for repairing or not?

    Is there some transistors with better characteristics that we can use?
