How Strict is the Drive Cycle?

[littlex5]

My E53 failed SMOG (O2 monitor not ready). I've been performing the drive cycle for many attempts with no luck. I'm wondering if the procedure I'm using does not meet the requirements.

This is the official BMW drive cycle...

1. Cold start for 2m10s
2. Drive 20-30 mph for 3m15s
3. Drive 40-50 mph for 15m
4. Coast to stop and idle for 5m

Since I'm not able to follow the procedure exactly due to where I live, this is what I do...

1. Cold start for 2m10s (w/ headlights, A/C, rear defroster on)
2. Drive on local streets (stop/go) for a few minutes to a street w/o stop signs/lights
3. Drive 22 mph for 3m15s (using cruse control)
4. Drive on local streets (stop/go) for a few minutes to a freeway onramp
5. Drive 57 mph for 15m (using cruise control)
6. Exit freeway and coast to stop (with brakes) and idle for 5m

Do you think my real-life procedure meets the drive cycle requirements?
