During my testing this morning, while standing on the driver side I noticed the fob red LED was flashing. But the driver triangle wouldn’t work no matter how I tried to use it. It has been this way consistently for several weeks now. My car has had zero issues unlocking automatically as I approach the driver side.
if I get time, I will try the other fob.
Inspired by your reply, I just conducted the experiment with my ID.4 (which, conveniently, is broken right now).
With the car locked but the fob in range, that fob LED pulses several times per second.
Unlocking using the “underneath” touch pads on the door handles produces 3 (?) very rapid flashes, the car unlocks, and the car then "silences" the fob LED; it goes dark and stay dark until something else happens.
On the (working) Passenger side, pressing the lock triangle apparently causes the fob to be interrogated. Its LED flashes once and then resumes the fairly-rapid “car is locked” pulsing.
On the (non-working) Driver side, pressing the lock triangle does nothing. I presume from this that the car doesn't know that anyone has touched the lock triangle because the door handle is broken.
Locking and unlocking the car from either side using the fob buttons works fine.
