O2 Sensor Not Ready: Won't Pass State Inspection
Hi All,
I took my car in the other day to Mini to get the timing chain tension measured and inquired about an external bulb out warning I was getting when all the bulbs were functional. I also decided to get my inspection while I was there. While this was being done I guess they tried to read any codes and ended up clearing anything that was in the car's memory. Keep in mind I didn't have any check engine lights on beforehand, I only had the external bulb out warning that popped up when cranking the car, then it would go away. So when they tried to inspect it, they said the O2 sensor was showing "not ready" and this was due to the clearing of the memory. The service rep told me to drive it approx 3 times and it would reinitialize the O2 sensor. So I drove it 10 separate times and then took it back the next day and it still had the same issue. This time the service rep told me to drive it for a week and it would surely be enough. I actually only drove it for 4 days and put ~100 miles on it and took it back today and it's still showing "not ready". Anyone have any idea of what is required for this to reinitialize?

My mystery 'bulb out' warning turned out the be the license plate lights in the rear.
Like the other post, the dealer should have known not to reset. I made that mistake last month when I took my tune off, and didn't have enough miles to show proper system function. I brought it back 4 days (and about 200 miles) later, and it passed emissions.
Hopefully your 3 hour ride will get everything working properly.
Have fun,
Mike

Check out the drive cycle instructions for VW cars!!
If a monitor is set to "Ready" the monitor is checking its assigned component and, if no DTC's are present, the vehicle should pass an emissions test.
The status of all readiness monitors is reset to "Not Ready":
Each time DTC's are cleared
The battery is disconnected
The ECM is disconnected
The status of all readiness monitors is reset to "Ready":
After DTC's are cleared and the appropriate drive cycle(s) is successfully completed
Completing the Drive Cycle successfully one (1) time should reset most drive cycle monitors to a "Ready" status. However, there are "two trip" monitors, which require that the drive cycle be successfully completed two (2) times, to achieve a "Ready" status. Furthermore, systems which use averaging, may require the drive cycle to be completed more than 2 times.
Before Beginning the Drive Cycle:
Check the status of the Readiness Monitors, check for DTC's, correct faults, clear DTC's before beginning the Drive Cycle.
Begin Drive Cycle:
The vehicle should be driven approximately 7.5 miles within a period of approx. 23 minutes (1372 seconds) from a cold start. However, due to manufacture variations, it is necessary to perform only as much of the Drive Cycle as is necessary to reset the required monitors to a "Ready" status. Operate the throttle smoothly to obtain best results. Do not shut the engine off during the drive cycle.
CAUTION: Obey all traffic laws and drive in a safe manner!
NOTE: Extreme driving conditioning such as very high/low temperatures, rough roads and high altitudes may prevent some monitors from attaining a "Ready" status.
Step 1 (Engine Cold) Start engine, idle 20 seconds. Accelerate gradually and drive at 20-25 mph for 1 minute, varying speed.
Step 2 Accelerate gradually to 32 mph within 35 seconds. Decelerate to 0 mph in 10 seconds. Idle for 40 seconds.
Step 3 Accelerate at part throttle to 25 mph in 10 seconds. Cruise at 17-25 mph for 15 seconds. Accelerate gradually to 57 mph in 45 seconds. Cruise at 50-56 mph for 1 minute. Decelerate gradually to 0 mph in 40 seconds. Idle for 15 seconds.
Step 4 Accelerate at part throttle to 36 mph and maintain for 10 seconds. Decelerate to 0 mph in 15 seconds. Idle for 5 seconds.
Step 5 Accelerate to 30 mph and back to 0 mph within 30 seconds. Idle for 20 seconds.
Step 6 Accelerate to 36 mph in 20 seconds. Drive at 35 mph for 20 seconds. Decelerate to 0 mph in 15 seconds. Idle 5 seconds.
Step 7 Accelerate gradually to 26 mph and decelerate to 0 within 40 seconds. Idle 15 seconds.
Step 8 Accelerate to 27 mph in 40 seconds. Decelerate to 0 mph in 10 seconds. Idle 25 seconds.
Step 9 Accelerate to 26 mph in 15 seconds, maintain speed for 10 seconds, decelerate to 0 mph in 10 seconds. Idle 15 seconds.
Step 10 Accelerate to 23 mph in 20 seconds, decelerate to 0.5 mph in 10 seconds (no complete stop). Accelerate to 28 mph and back to 0 mph (momentary stop 1 second) within 35 seconds.
Step 11 Accelerate gradually to 34 mph in 45 seconds. Vary speed between 34 and 19 mph for 2 minutes. Decelerate from 25 to 0 mph in 25 seconds. Idle for 5 seconds.
Step 12 Accelerate to 29 mph in 15 seconds, decelerate gradually to 0 mph in 45 seconds. Idle for 30 seconds.
Step 13 Accelerate gradually to 28 mph and back to 0 mph (momentary stop 1 second) within 50 seconds. Accelerate gradually to 27 mph and back to 0 mph within 55 seconds. Idle for 15 seconds.
Step 14 Accelerate to 24 mph and back to 0 mph within 18 seconds. Idle for 10 seconds. Accelerate gradually to 22 mph and back to 0 mph within 50 seconds. Idle for 8 seconds. Step 15 Accelerate gradually to 30 mph within 50 seconds. Decelerate to 0 mph in 10 seconds. Idle for 25 seconds.
Step 16 Accelerate to 23 mph and back to 0 mph within 30 seconds. Idle for 10 seconds.
Step 17 Repeat steps 1 - 16 once again. Recheck the status of the "Readiness Monitors".
NOTE: Remember, clearing DTC's or interrupting power to the ECM after the readiness monitors have been reset to "Ready" will require that the Drive Cycle be repeated.
