Why won't my Audi A7 start when it's cold outside?

I have a 2018 Audi A7 and it never has trouble starting in warmer weather, but when the temperature drops below freezing it won't start at all. I've had the battery and starter checked and they're both in good condition. What could be causing this issue?

Based on your description, it sounds like your engine may be struggling to turn over in cold temperatures. This could be due to a weak spark or fuel system issues. I recommend getting a diagnostic check at your local dealership or mechanic to pinpoint the exact cause.
