Emmision Related Problems Help!!

Hello all,

I am currently driving a 2004 545I 6 speed manual. I am having trouble passing the emission test because my Evaporate system and secondary air monitors are "not ready".

I have driven over 2500 kms since replacing my breather control valve and gas cap which was originally giving me my check engine light. The MIL light has not returned on and there are no codes stored.

I have attempted to complete the "drive cycle" to the best of my ability over 5 times. With that being said, it is difficult at times to follow the cycle on point. Today, I dropped my car at my buddies shop and had him accurately complete 3 drive cycles on the dyno, and still the windows are not ready.

Any help will be very appreciated! I have been dealing with this for weeks so my next plan is contact BMW tomorrow and see if I am able to bring the car in for them to get my monitors ready and do the emission test.
