Electrical issues. Radio. Headlight adjustment. Durametric codes.

Two current problems on car. 2004 Cayenne S.
(1) When turning on headlights, I get "Check Headlight beam Adjustment" error. But All headlight functions are normal.
(2) Radio doesn't work at first. After long drive, Porsche logo comes out, cycles then shows error while loading. After it does this, If i turn off car and then back on, radio's back to normal.
Batteries are about 4years old. So I decided to replace both batteries, but problems remain.
Scanned Electrical system with Durametric. Here are the codes:
968-Right direction indicator light-Upper limit value exceeded.
1498-Parking light right-Open circuit/short circuit to B+.
1499-Right full beam-Open circuit/short circuit to B+.
70-Starter battery voltage (second battery)-Implausible signal.
668-Vehicle voltage terminal 30-Implausible signal.
466-Steering column switch (with electronic unit)-No signal/communication.
907-Low management operat. On vehicle electrical sys./DME control module-No additional fault status available.
1299-Gateway-Please read out fault memory.
2087-Corner sensitive headlight right-Open circuit/short circuit to B+.
1520-Rain sensor/light sensor-Implausible signal.
2197-Potentiometer for footwell lights-Implausible signal.
2196-Terminal 30 fuse for vehicle electrical system control module-Upper limit value exceeded.
Thinking of replacing the level sensor but I see one each at front/rear suspension driver side. So not sure which one to replace or likely culprit. Both looked attached fine. Any other means to check any of these are bad?
Also checked a bunch of stuff, headlight wires, battery terminals, etc. All looked ok. Any other ideas?

I'm working through electrical issues on my 04 ctt also. I've read that when a few of the body drains plug up, you get water in the foot wells (passenger or driver side, depending on which get plugged) and the resulting dampness can corrode the CANBUS connectors. I'm not saying that's it for sure, but feel around to see if your carpet is wet.
