Hello everyone,
Bringing this thread back from the abyss.
My 2012 X1 xDrive28i keeps giving me an engine misfire. I've made the terrible mistake of taking it to BMW… they told me it was possibly the charge pressure sensor and charged me $900.
Much to my dismay, on my way home from BMW I got the engine misfire warning again. I did some digging when I got home and I'm thinking it's a problem with my vacuum pump or solenoid. You can see oil on the plugs (please see attached pic).
Can anyone advise me on what to do here? Has anyone encountered the same problem? I have no idea if I should get a new vacuum pump as well as solenoids or just the non return valve that supplies the waste gate actuator. I've also seen 'N20 vacuum pump repair kits' such as this:

I heard that some n20's have an actuator and some are electronic. Does it matter which one I have?
Thank you in advanced.
