    740LI rail pressure

    Hi please help me with this problem it has been 8-9 months im getting this code rail pressure sensor, plausibility preasure to high, it suddenly throws drivetrain fault with misfire fan speed gets to maximum i could hear loud fan at full speed i restart my car it goes away but my car shakes when it reaches 800RPM once give some acceleration it gets fine, and cold starts it vibrates not badly but it does i live in dubai so weather over here is always warm 30-50 degrees. And it dosent stall at all sometimes it takes long starts.
    I have replaced high pressure fuel pump (got it used one) and new sensor.
    New alternator
    New spark plugs platinum
    One coil was broken i replaced that to new bosch.
    There was a pipe left side of engine vaccum pipe maybe it was torn off i replaced that one to still im. Getting this fault is it LPFP or fuel filter what it could be leaky fuel injectors? i never replaced them or got it Cleaned.

    My car milege 168,000 KM
    2010 740LI 3.0 litr twin turbo N54 engine.

    Sorry for my bad english.
