2019 Audi S4 — delayed engagement into Drive when cold

If it were in my driveway, two 2019 Audi S4s 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 2019 Audi S4 in Miami. Keep sale price, fees, and rate as three different conversations. I'd rather be boring and correct. Heat soak after errands is the other window.

OP update: scanned the 2019 Audi S4 again and still only have the one pending code, no new lights. No warning lights, which is why I'm documenting it.

Checked the easy stuff on the 2019 Audi S4 and found one clue worth chasing before I book a shop. This is the version I'd tell a friend.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2019 Audi S4, bring a video plus freeze-frame data, not just a story. Don't erase codes until someone who can help has seen them. Verbal 'we'll take care of it' is not a plan. If the story changes I'll post the new data.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Verbal 'we'll take care of it' is not a plan. Heat soak after errands is the other window.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2019 Audi S4 and see if the fault moves. You'll know quickly if you're on the wrong tree. Verbal 'we'll take care of it' is not a plan. Trying not to diagnose from the couch.

Intermittent stuff lies if you only catch it once. If a shop can't duplicate it on the 2019 Audi S4, bring a video plus freeze-frame data, not just a story. You'll know quickly if you're on the wrong tree. On “delayed engagement into drive when cold,” that was the fork that mattered for me. If you share a photo of the worksheet, easier to sanity-check. Not interested in a five-hour wait for a shrug.

If it were in my driveway, two 2019 Audi S4s can feel identical and have different causes, so measure before you copy someone else's repair. You'll know quickly if you're on the wrong tree. Do that first. I'll update if anything new shows up.

Intermittent stuff lies if you only catch it once. A pressure test beats staring at a dry driveway if the 2019 Audi S4 is losing coolant with no puddle. If the cheap test changes it, stop and reassess. On “delayed engagement into drive when cold,” that was the fork that mattered for me. I'd want that in writing, not as a promise. If this is nothing, great. I want that in data.

I wouldn't throw parts yet. Two 2019 Audi S4s 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 2019 Audi S4 in Miami. Do that first. I've seen both outcomes, which is why I'd test instead of assume. Might be overthinking it, but I'd rather overthink than overspend.

Log the conditions before you spend. Move a coil or plug on the 2019 Audi S4 if it's cylinder-specific and see whether the code follows. If the cheap test changes it, stop and reassess. On “delayed engagement into drive when cold,” that was the fork that mattered for me. Had a similar mess a couple years ago and that's what finally sorted it. This is the filter I use when the thread starts repeating itself. Heat soak after errands is the other window.

Tried a second charger / second scan and the story on the 2019 Audi S4 didn't change. Not driving it hard until I know more.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2019 Audi S4 is losing coolant with no puddle. Don't erase codes until someone who can help has seen them. That's the sequence I'd use. Video is ugly but it shows the hesitation.

Start with the test that can prove you wrong. Get a real battery/charging test on the 2019 Audi S4, not just resting voltage, before blaming a module. That's the branch I'd chase this week. This is from a 2019 Audi S4 in Miami. If you share a photo of the worksheet, easier to sanity-check. Trying not to diagnose from the couch.

On “delayed engagement into drive when cold,” that was the fork that mattered for me. A shop burned me once by skipping that step. I'm in no rush to be a hero on it.

It did delayed engagement into drive when cold twice this week, both times after sitting. No change in mileage feel. Happens in gear, not in park, for what that's worth.

If it were in my driveway, capture voltage while the 2019 Audi S4 is actually failing — after it restarts you've lost the clue. That's the branch I'd chase this week. That's the whole play. Not interested in a five-hour wait for a shrug.

I went back under the 2019 Audi S4 and it only happens after a heat soak, not on a cold start. Checking again after work.

I'd want a measurement, not a hunch. Get a real battery/charging test on the 2019 Audi S4, not just resting voltage, before blaming a module. You'll know quickly if you're on the wrong tree. Time, temperature, and whether it's in gear are the notes that actually help a shop. Might be overthinking it, but I'd rather overthink than overspend.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. On “delayed engagement into drive when cold,” that was the fork that mattered for me. If it doesn't change the out-the-door or the repair estimate, it's noise. Wrote this up on my lunch break.

I wouldn't throw parts yet. Write temp, speed, and in-gear vs coast when the 2019 Audi S4 does it — then decide on parts. If the cheap test changes it, stop and reassess. Stop there until you know. Worth doing even if the car feels fine right now. I'd rather look cautious in this thread than stuck later.

Ask what changed right before it started. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. You'll know quickly if you're on the wrong tree. Do that first. Parking it somewhere I can hear it better next time.

Log the conditions before you spend. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. On “delayed engagement into drive when cold,” that was the fork that mattered for me. Learned this the expensive way on a previous car. Climate here is different, so treat that as a local data point. If this is nothing, great. I want that in data.

Start with the test that can prove you wrong. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. Save the big job until that test fails. Learned this the expensive way on a previous car. If that fails I'll eat the diagnostic fee.

I'd want a measurement, not a hunch. Swap the cheap/easy piece first on the 2019 Audi S4 and see if the fault moves. You'll know quickly if you're on the wrong tree. That's the whole play. Next check is the cheap one I can do in a driveway.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2019 Audi S4 does it — then decide on parts. Save the big job until that test fails. I'd want that in writing, not as a promise. Make the next action something you can finish this week. If it repeats twice more I'll book time.

Tried a second charger / second scan and the story on the 2019 Audi S4 didn't change. I'd rather pay for diagnosis than a second guess-repair.

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2019 Audi S4 catch play that a wheels-hanging inspection misses. Save the big job until that test fails. Post the numbers (or the code) and people can get more specific. I'd sleep better after that step, even if it finds nothing. This is me being the wet blanket on purpose.

Cleared nothing. I want service to see the alert on the 2019 Audi S4 first. I'm keeping receipts and dates in one folder.

On “delayed engagement into drive when cold,” that was the fork that mattered for me. Post the numbers (or the code) and people can get more specific. This is the filter I use when the thread starts repeating itself. I refuse to clear codes until someone else sees them.
