Oil Pressure, Battery, Power Steering Issues - ECU Related?

So I have a 2008.5 GTi with the TSi motor and this week it started acting a little crazy. About 5 minutes into a drive the oil pressure light came on and my OBD app showed zero oil pressure. I was still on my street so I just turned around and drove home, but in those <5 minutes the battery light came on. When I locked the car the horn sounded like the battery was low, which it definitely shouldn't be.

I gave it a day and tried starting it again today, it started fine with no oil pressure light or battery light, but now the power steering light is on and I have no power steering.

From experience my guess is that my ECU is shot, but I'm definitely up for suggestions. Thoughts?

Can you post a scan of all of its fault codes?

@ROH ECHT I don't believe it was throwing any when I checked oil pressure, but I'll go check it today and see what it returns. I have been randomly throwing a throttle position sensor fault for a year or so. (I know I shouldn't, but I didn't have a place to work on it)
