Why does my Audi A3 not start after driving in heavy rain?

I have a 2015 Audi A3 and every time I drive it in heavy rain, the car fails to start afterwards. This has happened on several occasions and I have to wait over an hour for the car to dry before it can start. What could be causing this issue?

It's possible that water is entering the engine and causing an electrical malfunction. I would recommend checking the seals and gaskets in the engine compartment for any signs of damage or wear.

It is possible that the ignition coils or spark plugs are getting wet and causing the issue. Ensure that they are properly sealed and replace them if necessary.
