2024 BMW i4 — rough idle disappears just above idle speed

If it were in my driveway, swap the cheap/easy piece first on the 2024 BMW i4 and see if the fault moves. If the cheap test changes it, stop and reassess. Not gospel, but it saved me a headache. I'd rather be boring and correct. I'll poke at it this weekend.

Start with the test that can prove you wrong. Write temp, speed, and in-gear vs coast when the 2024 BMW i4 does it — then decide on parts. That's the branch I'd chase this week. I'd want a dollar figure or a measured spec, not 'should be fine.' If this is nothing, great. I want that in data.

OP update: scanned the 2024 BMW i4 again and still only have the one pending code, no new lights. Checking again after work.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2024 BMW i4 is losing coolant with no puddle. If the cheap test changes it, stop and reassess. Take it or leave it — that's what I'd do. This is the version I'd tell a friend.

This is usually cheaper to test than to guess. Move a coil or plug on the 2024 BMW i4 if it's cylinder-specific and see whether the code follows. You'll know quickly if you're on the wrong tree. Was this after sitting overnight? Not interested in a five-hour wait for a shrug.

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2024 BMW i4, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. Keep sale price, fees, and rate as three different conversations. No warning lights, which is why I'm documenting it.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2024 BMW i4 and see if the fault moves. If the cheap test changes it, stop and reassess. Keep sale price, fees, and rate as three different conversations. Wrote this up on my lunch break.

It did rough idle disappears just above idle speed twice this week, both times after sitting. No change in mileage feel. If it repeats twice more I'll book time.

This is usually cheaper to test than to guess. Two 2024 BMW i4s can feel identical and have different causes, so measure before you copy someone else's repair. Don't erase codes until someone who can help has seen them. If you share a photo of the worksheet, easier to sanity-check. Doing the boring step first on purpose.

Log the conditions before you spend. Write temp, speed, and in-gear vs coast when the 2024 BMW i4 does it — then decide on parts. You'll know quickly if you're on the wrong tree. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. This is from a 2024 BMW i4 in Tampa. Did the worksheet show tax yet? If your situation is the opposite, ignore me. I already checked the easy fluid levels.

Ask what changed right before it started. Get a real battery/charging test on the 2024 BMW i4, not just resting voltage, before blaming a module. Save the big job until that test fails. Post the numbers (or the code) and people can get more specific. Make the next action something you can finish this week. I'd rather pay for diagnosis than a second guess-repair.

Log the conditions before you spend. Capture voltage while the 2024 BMW i4 is actually failing — after it restarts you've lost the clue. If the cheap test changes it, stop and reassess. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. This is from a 2024 BMW i4 in Tampa. Any freeze-frame data saved? Climate here is different, so treat that as a local data point. If it repeats twice more I'll book time.
