Edit: It just started. I left the JNC on longer than before and I guess it juiced it up enough. Now I need to figure out why the battery died... (maybe I left the door open in the garage or something.)
What are the signs of a dead/dying battery on a MK7? Or, if not battery, starter?
I'm mostly unmodded except for upper and lower dogbone inserts, short shift adapter, clutch valve delay removal, etc. - I recently installed my JB4 and everything has been going fine running Map 3. I got into the car yesterday morning and it wouldn't start. Push the button, click, all the lights come on, Check Engine and EPC lights both stay on after it doesn't turn over. If I hold down the push button, it clicks repeatedly.
I got some random warnings like something about lights not enabled, front assist disabled, key not found, etc. (I tried my spare key and same thing happened.)
I have a Jump n Carry and tried to jump it off with that but it hasn't worked.
Before I go taking it to the dealer (removing JB4 first) I wanted to check with you all to see what your thoughts are, or next steps for diagnosing the issue. I could try jumping off my wife's car but would need to roll it out of the garage which I haven't wanted to do just yet.
Any help would be appreciated.
Edit: No faults stored in JB4 codes section.
