How to verify battery drain issue?
I’ve installed an RCD330 and swapped the gateway in my VW Passat B6. How do I check if I’m going to run into battery drain issues? Is there a way to verify it without any extra tools?
Everything seems the same so far - I can still use the radio with the ignition off, and my phone keeps charging.
