Hi gang,

I have a 2009 GT TDI, it has been going great for the past 4 years however I have always had issues with the battery. I have had my battery replaced 3 times now, yet it still seems to drain and every week or month I will have at least one start-up that struggles.

This has caused my Dual Mass Flywheel to degrade, my starter motor to degrade, and I have never been able to solve it.

I have taken it to a mechanic and asked before, and they said it was the glove box light, I unplugged it and yet still have the issues.

What is the best way to track this down?
I do have:
- An RNS-510, when I installed it I made sure I had the right can-bus module version, but to check, what should it be?
- A subwoofer and amp wired to the back of the RNS-510, I have unplugged this from the battery and still have the issue.

Can anyone help me? I am scared to take it to another mechanic, spend so much money, and come out no where, and I don't want to spend another $300 on a battery.
