2016 Audi A4 — surface rust underneath a winter daily

I'd want a measurement, not a hunch. Loaded-suspension checks on the 2016 Audi A4 catch play that a wheels-hanging inspection misses. Don't erase codes until someone who can help has seen them. If it doesn't change the out-the-door or the repair estimate, it's noise. I'd sleep better after that step, even if it finds nothing. I refuse to clear codes until someone else sees them.

This is usually cheaper to test than to guess. If a shop can't duplicate it on the 2016 Audi A4, bring a video plus freeze-frame data, not just a story. 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.' Parking it somewhere I can hear it better next time.
