2019 Volkswagen Atlas — battery dies after the car sits for a weekend — anyone dealt with this recently?

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2019 Volkswagen Atlas is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. Had a similar mess a couple years ago and that's what finally sorted it. Might be overthinking it, but I'd rather overthink than overspend.

This is usually cheaper to test than to guess. Move a coil or plug on the 2019 Volkswagen Atlas if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. Time, temperature, and whether it's in gear are the notes that actually help a shop. A day of patience here is cheaper than a wrong part. If the story changes I'll post the new data.
