See attached. It also seems like there was some PCM update on early model year cars that addressed this issue.

I removed my battery a few weeks ago and my Q4 reads I/M ready on my scan tool.

I have learned that most cars just need to be driven in various conditions with various speeds and idling for a set amount of mileage or driving time(exact number unknown) to clear all the I/M requirements.

I drive my Q4 60 miles a day to work and back which includes idling at stoplights and some highway driving. After about a week on my commute my cars generally clear the I/M readiness check including my Giulia.

Note: I have a Toyota that took forever to get an ready I/M after a battery change, but all I did was just drive it about 10 minutes around town for about three weeks. I had to drive it for 10-15miles for a few days on the highway and on the normal roads with stop lights to get it to clear on the scan tool.

 

Sounds like it’s known —

EMISSIONS CONTROL OPERATION

NOTE: The ambient temperature for the entire driving cycle is required to be between 7°C (45°F) and 35°C (95°F) otherwise the EVAP monitor will not run.

Performing Oxygen Sensor Adaptation

1. Bring vehicle up to operating temperature.

2. With the vehicle in Normal mode and in 6th gear, accelerate the vehicle smoothly up to 96 km/h to 110 km/h (60 to 70 mph) keeping the accelerator pedal as stable as possible.

NOTE: The accelerator pedal has to be operated smoothly from 0% to 20% and then has to be kept almost constant.


3. With the vehicle in Normal mode and in 7th gear, accelerate the vehicle smoothly up to 96 km/h to 110 km/h (60 to 70 mph) keeping the accelerator pedal as stable as possible.

NOTE: The accelerator pedal has to be operated smoothly from 0% to 20% and then has to be kept almost constant.

4. With the vehicle in Normal mode and in 8th gear, accelerate the vehicle smoothly up to 96 km/h to 110 km/h (60 to 70 mph) keeping the accelerator pedal as stable as possible.

NOTE: The accelerator pedal has to be operated smoothly from 0% to 20% and then has to be kept almost constant.
Performing Exhaust Gas Recirculation (EGR) Monitor
1. Bring vehicle up to operating temperature.

2. While using 5th gear, perform several vehicle revolutions (accelerator pedal greater than 75%, intake efficiency greater than two, and EGR position greater than 20%).

3. Both monitors for EGR should run properly (high flow and low flow).

Performing the Evaporative (EVAP) Monitor

• Day 1

1. Turn the engine ON and stay in idle for 1 minute.

2. Drive the vehicle for 20 minutes while maintaining a vehicle speed between 96 km/h to 110 km/h (60 to 70 mph).

NOTE: Operate the vehicle as constant as possible.

3. Turn the engine OFF and leave the car in soak for the rest of the day/night.

• Day 2

1. Turn the engine ON and idle for 1 minute.

2. Operate the vehicle for 20 minutes while maintaining a vehicle speed between 96 km/h to 110 km/h (60 to 70 mph).

NOTE: Operate the vehicle as constant as possible.

3. At the end of the drive cycle the EVAP monitor will be complete (passed).

 

That procedure absolutely never worked on my 2.0T.

You need to operate the engine over a wide variety of conditions in a single drive cycle. Do everything from WOT runs, a 20 minute highway cruise, getting stuck in bumper to bumper traffic, and typical city driving with tons of stops/starts. Also disable the auto start/stop while doing this.

 

Any insight if a tune will cause it?

 

I disabled my JB4 while trying to get them to reset. It took like 3 or 4 weeks.
