Looking at the driving cycle instructions posted by @littlex5 in post #13, I have a question:

When it says in the last part idle in gear does that mean leave it in Drive while it idles for five minutes?

I have had some difficulty completing driving cycle loops on my various vehicles, usually due to traffic and lack of clear roads. Especially when you've had to clear codes after a repair and your inspection is almost overdue (but still within the grace period).

Once, I had to get a temporary permit for my HHR Panel, when I hadn't repaired it after retirement (it was my daily driver, and I let it sit for 10 months, before I needed to fix it...at inspection time). It wouldn't reset two of the monitors, so I got a 10-day permit, and ended up driving just short of 300 miles before all monitors went green! Took 10 trips over 4 days, if I remember correctly.

My 2500HD Chevy took almost 500 miles, and still had Evap as incomplete, but in Texas, that's OK to have one incomplete, so 6 days of driving cycles finally paid off. But, last month, I had to clear a tranny code, and I feared that it would repeat the extended drive cycle fiasco, but it was OK (Evap still not OK, though) after just one drive cycle...go figure.

Now for the X5. I cleared codes with my Foxwell last year, a month before inspection, but never drove the drive cycle, just my normal grocery shopping route (4 trips, I think). It was almost perfect on inspection day! However, a week or so afterwards, I started getting lean codes and CEL's, which plagued me for many months (almost a year) https://xoutpost.com/bmw-sav-forums/...hrowing-codes-. It's inspection time again, and I won't even change my oil, in fear of screwing up the monitors before it passes https://xoutpost.com/1224825-post95.html.

And yes, idling in gear is to simulate sitting at a stoplight.
