1999 740il Owner Needs HELP!

[Stim8er]

I need some help guys.... I recently rebuilt the front end of my 1999 740il because of a noise and P1519 and P1522 codes.... I found the chain guides destroyed soooo, replaced all chain guides, tensioners, actuators, CPS Sensors, vanos units, OSV, tube from front timing cover to rear for OSv, all gaskets, o-rings, etc... including intake manifold... NO LEAKS! yea...... got the BMW timing kit and re-timed three (3) times now and still getting P1519, P1522 and now P1384 for knock sensor... Idles like crap!!! higher rpms and P1519 and P1522 go away for a minute and then RAT-TAT-TAT-TAT... sounds like vanos gone bad on steroids...

PLEASE HELP! Tired of tearing it apart and redoing everything......
