B5 A4 Oil pressure and temp issues
Sorry for the long read but I wanted to give you guys as much info as possible..
So a couple of weeks ago I was driving my B5 A4 2.8 AFC non quattro and the oil pressure light comes on. Didn't think anything of it since it went back off after about 2 seconds. A week later I drive to work and stop at WAWA for my coffee, I turn my car on and drive away the oil pressure light turns on, I stop at a light and it goes off again, around 2000 RPM it comes back on but as I'm driving it shuts back off. Same day after work, same deal, I stopped somewhere and turn the car on and drive light goes on except this time it stays on. Car was running fine, no issues no loss of power, oil level was good, so I drove home. 2 days ago though same thing happens but this time it loses power and then picks back up, like a fuel delivery issue. I noticed an oil leak coming from the pressure sensor around the time when my light started turning on, which I have I just need to install. But my car takes a really long time to even read the oil temp in the cluster, I'm barely getting any heat and I just put in a new Thermostat last weekend. (I only mention this because the research I have done states that coolant temp might possibly affect the oil temp, which in turn can be affecting my lack of heat issue.) What can be causing my power loss, long warm up period and no heat? I've searched everywhere but only seem to find info on 1.8t engines. And lots of confusing info like the pressure sensor doubles as an oil temp sensor.

Hi Randy,
The best way to initiate your troubleshooting is to scan your car and come back with the results.
A scan will be able to point out a faulty sensor or a deeper underlying problem.

Update, these are the only codes in getting if this helps any..
(17509) P1101 02 sensor b1s1 (I have a couple of o2 sensors that the wires are ripped out because of previous owner)
(18014) P1606 rough road/engine torque signal from ABS electrical malfunction cylinder 4
ABS system codes usually it's just the relay code but these two popped up as well
These are the codes from the AC system, after I cleared the codes these few remained..
Most of these cleared away so I'll explain briefly why a few have stayed on
So I have no outside air temp sensor, recently discovered this 
I have no air compressor so that's why the a.c. switch is up there
Footwell and center cent temp sensors are new as well
