I've got a 2015 3.0 TDI that I'm rebuilding. Not a mechanic by any means, but I'm comfortable doing basic stuff and following YouTube videos.

That said, I'm pretty weak when it comes to troubleshooting, especially when it comes to electrical, so I was hoping you guys could help an idiot out and tell me a few things to check.

Just did a starter swap. It cranked beautifully and ran great for a day, but began to crank slugglishly and now won't crank and at all and I'm getting the error codes (full VCDS scan pasted below):

"5463 - Starter Control; Returned Message P3052 00 [167] - 50 Short to Plus"

"22944 - Shift Solenoid 2 P0977 00 [171] - Short to Plus"


Some background on the car and the issue.

I swapped the engine a few months ago and it ran fine for a few months until it began to crank very sluggishly and sometimes wouldn't crank until I jump-started it.

Battery wasn't the issue as it was just replaced and was always around 12.6V when not running. Alternator kept the battery running. I suspected the starter, so I bought one off of Ebay and swapped it out (that wasn't easy!).

It ran great with the new starter for a day, but then cranked sluggishly a few times and now won't crank at all.

QUESTIONS:

1. What are some things on here that you guys would check based on my symptoms?

2. I read that I should start by testing the starter relay. I borrowed the test kit from O'Reily's. Does anyone know where I can find the specific fuse box layout for my model of Touareg? All the ones I'm finding online are slightly off in some ways. The relay they all seem to identify as the "starter relay" comes up as the Glow-Plug relay on VW parts (PN 4L0907282A).

Full text from the VCDS scan (the codes about the driver's door and alarm horn have been on there forever, haven't gotten around to them yet):
