2024 Polestar 2 — check-engine light turned itself off — still scan it?

2024 Polestar 2 Long Range Dual Motor, about 2,500 miles. The light was on for two days and then disappeared before I could schedule service. Car feels normal. Is there still likely to be useful stored or pending data if I scan it now? I am in Philadelphia.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2024 Polestar 2 is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. I'd want a dollar figure or a measured spec, not 'should be fine.' If this is nothing, great. I want that in data.

This is usually cheaper to test than to guess. Move a coil or plug on the 2024 Polestar 2 if it's cylinder-specific and see whether the code follows. Save the big job until that test fails. Keep sale price, fees, and rate as three different conversations. If this is nothing, great. I want that in data.

If it were in my driveway, two 2024 Polestar 2s can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. This is from a 2024 Polestar 2 in Philadelphia with 2,500 miles. Time, temperature, and whether it's in gear are the notes that actually help a shop. Not trying to scare you — just skip the expensive first guess. If that fails I'll eat the diagnostic fee.

That's a good start, but I wouldn't stop there. If a shop can't duplicate it on the 2024 Polestar 2, bring a video plus freeze-frame data, not just a story. That's the branch I'd chase this week. This is from a 2024 Polestar 2 in Philadelphia with 2,500 miles. Verbal 'we'll take care of it' is not a plan. Happens in gear, not in park, for what that's worth.

Same neighborhood, different next step: Move a coil or plug on the 2024 Polestar 2 if it's cylinder-specific and see whether the code follows. That's the branch I'd chase this week. On “check-engine light turned itself off — still,” that was the fork that mattered for me. Run the total, not the monthly, before you commit. This is the version I'd tell a friend.

Ask what changed right before it started. A pressure test beats staring at a dry driveway if the 2024 Polestar 2 is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.
