2015 Volkswagen Golf — no crank with full dash power, then it starts later

This is usually cheaper to test than to guess. A pressure test beats staring at a dry driveway if the 2015 Volkswagen Golf is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. Write the result down so the next test isn't a repeat of the last one. If this is nothing, great. I want that in data.

It did no crank with full dash power, then twice this week, both times after sitting. No change in mileage feel. Checking again after work.

If it were in my driveway, a pressure test beats staring at a dry driveway if the 2015 Volkswagen Golf is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. Do that first. Happens in gear, not in park, for what that's worth.

This is usually cheaper to test than to guess. Two 2015 Volkswagen Golfs can feel identical and have different causes, so measure before you copy someone else's repair. Save the big job until that test fails. This is from a 2015 Volkswagen Golf in Austin with 123,000 miles. Did the worksheet show tax yet? Make the next action something you can finish this week. Doing the boring step first on purpose.

Ask what changed right before it started. Write temp, speed, and in-gear vs coast when the 2015 Volkswagen Golf does it — then decide on parts. Don't erase codes until someone who can help has seen them. I'd want a dollar figure or a measured spec, not 'should be fine.' I'd rather look cautious in this thread than stuck later.

Log the conditions before you spend. Two 2015 Volkswagen Golfs 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. On “no crank with full dash power, then,” that was the fork that mattered for me. That's the whole play. Trying not to diagnose from the couch.

Intermittent stuff lies if you only catch it once. Loaded-suspension checks on the 2015 Volkswagen Golf catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. On “no crank with full dash power, then,” that was the fork that mattered for me. That's the whole play. Checking again after work.

OP update: scanned the 2015 Volkswagen Golf again and still only have the one pending code, no new lights. Video is ugly but it shows the hesitation.

I wouldn't throw parts yet. Swap the cheap/easy piece first on the 2015 Volkswagen Golf and see if the fault moves. Don't erase codes until someone who can help has seen them. This is from a 2015 Volkswagen Golf in Austin with 123,000 miles. Write the result down so the next test isn't a repeat of the last one. If the story changes I'll post the new data.

If it were in my driveway, write temp, speed, and in-gear vs coast when the 2015 Volkswagen Golf does it — then decide on parts. If the cheap test changes it, stop and reassess. Have you gotten a second quote in writing? I'd sleep better after that step, even if it finds nothing. I keep a notes app thread for this now.

I'd want a measurement, not a hunch. A pressure test beats staring at a dry driveway if the 2015 Volkswagen Golf is losing coolant with no puddle. You'll know quickly if you're on the wrong tree. That's the whole play. Might be overthinking it, but I'd rather overthink than overspend.
