Cylinder 4 Misfire Detected: so, you could check that cylinder specifically.

Lots of possibilities; read the above links, to start doing some testing and a process of elimination. You have just about; replaced everything that controls the engine! Did you use; high quality parts for: maf, wires, coil, spark plugs, sensors etc. poor quality parts, can cause even more problems and complicate, you troubleshooting process!

A "hard" reset; can never hurt, remove positive and negative battery cables, touch together for 30 seconds and re-install.

One thing; that I noticed, you didn't do... was clean the throttle body and realign/adapt using VDCS. Maybe, after all these years; it might need to be realigned? Worth a shot; people have mentioned fixing poor idle issues by doing this! Aside from that; it seems to me, #4 cylinder misfire is your primary issue, you need to figure out.

What scanner; are you using (hand held, VCDS lite, full etc.)?

Using VCDS: choose: control module: engine: measuring blocks: channel 019? Should show misfire counter and show which cylinder is the problem. This would be in real time (engine running); so, it would confirm #4 and eliminate other possible misfires. Other channels; show more info, just click on the button and click the "up arrow" to see more info, on other channels.

Wow! Very cool; on the throttle body cleaning; every time I have done this cleaning/adaptation, I can't believe the difference it makes! Many have said; the 2.0L TB can get really dirty and will kill power of the engine. I'm so glad; things seem much better!

On the door unlock issue; are you saying you replaced the door control module or just the actuator? I wonder; if that dcm, needs to be adapted to the ecm?

I would start testing; for power at the switches, unlocking actuator/switch, it maybe the wiring has problems (many people; have had wiring insulation/wires break near the hinges). Any codes with VCDS; there are probably output tests for the actuator. You might try removing switches on the "good" side and vice/versa ; to confirm that they are good/bad.

By the way; "chicken/mangos", makes me wonder where you live! Why not start a threat; showing off your new beetle and some info, about where you are from? It would be nice; if you wold fill in your year/model of your beetle and location.
