BMW S50B32 DUAL VANOS - Int vanos Error

[Adamw]

I just done a quick test on the bench, the aux test PWM function doesnt actually work when the VVT system is set to S52 mode, the auxes must be linked together in the software when in this mode.  So to test the auxes you have to temporarily set the VVT mode to off, then you can try Test PWM on each aux.  

I still dont see the reason for the position error on the intake cam.  Can you do another short log with the cam angle test set to LH intake and give it a few revs to where the error normally occurs.  

What do you have for coils and ignitors on this engine?

aux 1 to the inlet brown wire 

aux 2 to inlet green wire 

aux 3  to exh brown wire

aux 4  to exh green wire 

12v to red and black wires .

every thing good .

thank you in advance

Have you tested the aux with VVT set to off?
