2019 Porsche Macan — footwell gets wet only after heavy rain

I'd want a measurement, not a hunch. Two 2019 Porsche Macans 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. I'd want that in writing, not as a promise. I'd sleep better after that step, even if it finds nothing. I'll update if anything new shows up.

This is usually cheaper to test than to guess. Write temp, speed, and in-gear vs coast when the 2019 Porsche Macan does it — then decide on parts. If the cheap test changes it, stop and reassess. This is from a 2019 Porsche Macan in Charlotte. No need to make it theatrical. I'll poke at it this weekend.

Checked the easy stuff on the 2019 Porsche Macan and found one clue worth chasing before I book a shop. Trying not to diagnose from the couch.

Log the conditions before you spend. A pressure test beats staring at a dry driveway if the 2019 Porsche Macan is losing coolant with no puddle. Save the big job until that test fails. On “footwell gets wet only after heavy rain,” that was the fork that mattered for me. I'd want that in writing, not as a promise. Only after sitting overnight so far.

Start with the test that can prove you wrong. If a shop can't duplicate it on the 2019 Porsche Macan, bring a video plus freeze-frame data, not just a story. If the cheap test changes it, stop and reassess. No need to make it theatrical. Worth doing even if the car feels fine right now. I already checked the easy fluid levels.

If it were in my driveway, loaded-suspension checks on the 2019 Porsche Macan catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. Not gospel, but it saved me a headache. If it repeats twice more I'll book time.

Ask what changed right before it started. Get a real battery/charging test on the 2019 Porsche Macan, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. This is from a 2019 Porsche Macan in Charlotte. Time, temperature, and whether it's in gear are the notes that actually help a shop. A day of patience here is cheaper than a wrong part. Happens in gear, not in park, for what that's worth.

Intermittent stuff lies if you only catch it once. Get a real battery/charging test on the 2019 Porsche Macan, not just resting voltage, before blaming a module. If the cheap test changes it, stop and reassess. On “footwell gets wet only after heavy rain,” that was the fork that mattered for me. That's the sequence I'd use. Checking again after work.
