2024 Audi Q5 — rough idle disappears just above idle speed

GarageGarage872Community StarterDec 18, 20252024 Audi Q5 Premium PlusChicago
2024 Audi Q5 Premium Plus, about 30,000 miles. Idle has a slight shake once fully warm, but 100–200 RPM above idle it smooths out. No major loss of power. Would you look at mounts, vacuum leaks, ignition or fueling first? I am in Chicago.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2024 Audi Q5, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. This is from a 2024 Audi Q5 in Chicago with 30,000 miles. Time, temperature, and whether it's in gear are the notes that actually help a shop. If this is nothing, great. I want that in data.

Intermittent stuff lies if you only catch it once. Capture voltage while the 2024 Audi Q5 is actually failing — after it restarts you've lost the clue. That's the branch I'd chase this week. On “rough idle disappears just above idle speed,” that was the fork that mattered for me. This is from a 2024 Audi Q5 in Chicago with 30,000 miles. Time, temperature, and whether it's in gear are the notes that actually help a shop. If it repeats twice more I'll book time.

I wouldn't throw parts yet. Loaded-suspension checks on the 2024 Audi Q5 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. Was this after sitting overnight? Checking again after work.

This is usually cheaper to test than to guess. Get a real battery/charging test on the 2024 Audi Q5, not just resting voltage, before blaming a module. Save the big job until that test fails. Verbal 'we'll take care of it' is not a plan. That's coming from doing this as an owner, not a shop. If this is nothing, great. I want that in data.
