The first thing I would do is New MAF and Air Filter because they are cheap and very easy DIY. If that doesn't work start doing the vanos and hard stuff.
In my 540i my Maf died twice so the engine goes flat around 200 hp instead of 282 hp
If first you don't succeed you must try again, and then again
