can you reach the solenoid connector without removing the intercooler? imma do it this weekend.

Also there is an EGR actual / commanded param in the AP. I had it side by side with the intake manifold temp.

EGR actual would be at 0 under medium -hard acceleration / idle. It was at 0 when you let off the pedal as well. It would go up under very light accel / cruise control. Everytime EGR actual went up, the intake manifold temps rised pretty quickly by 20-30 degree. They would drop wheb EGR was 0.

tldr EGR Actual 0 = Valve closed.
You can verify it stays closed after been uplugged by looking at your intake manifold temps.

Yes you can do it without removing the intercooler! It is an extremely tight fit, but you can reach it through a gap in the intake manifold. I used one finger and a screw driver to position it just right to remove it. It took me a bit of straining as I have big hands, but was able to get it after about 10 minutes.

I actually just did this earlier this week.

if you look in from the front you can see the plug. use a long flat head screw driver so you can depress the release button and give it a small push to unseat it and ensure it doens't lock back in. Then reposition the screw driver closer to the end of the plug(there's a small block you can push against) and the plug pops right off.

You can get this done in a few minutes.

Within a few days of unplugging my EGR solenoid I got a P2270 OBD-II Trouble Code: O2 Sensor Signal Stuck Lean Bank 1 Sensor 2. This happen to anyone else? Any insight on how/if they can be related at all?

Are you tuned for an unplugged EGR?

Yeah I unchecked the nine trouble codes relating to EGR operation. The P2270 Second O2 stuck lean code was not one of them.

I believe you have to zero out a few tables (4 I believe) which adjust fuel mixture depending on EGR position. The ECU adjusts fuel mixture based on what it commands the EGR to do, even though it's unplugged. Since exhaust gases have some un-burnt fuel in them, the ECU removes some fuel when the valve is open. Since the valve isn't connected and closed all the time, the engine is sometimes running lean since these gases are no longer entering the combustion chamber. By zeroing out the tables it doesn't adjust fueling which should prevent the lean condition.
