A 1997 e36 M3 that I shouldn't have bought :/

The ECU doesn't know or care about low oil pressure, page 6211.0-00 of the ETM shows that the pressure switch does nothing but light up the light.  Did you pull a bearing cap while you had the pan open to see what they looked like?

Unfortunately I didn't. I ran a magnet in the pan for any metal shavings and it came out clean.

I doubt you would see any metal shavings.  Bearing material isn't magnetic anyway.  You should put some miles on it to see if it seems normal otherwise anyone that knows what happened wouldn't touch it with a 10 foot pole.  It might be just fine and then you can sell it for possibly more rather than someone considering that they might need to put a different engine in due to running without oil pressure.

I'm not trying to be rude but I wouldn't buy it for $2000 knowing what's happened to it.  Now if you had driven it 5k miles since then without problems then my concern would be much lower.

Might be a good idea to get 3-5k on it and do a Blackstone labs oil analysis, that would likely tell you if there is any excessive wear going on.

Totally understandable. I put a few miles on it before it started to snow and I didn't notice anything out of the ordinary. But Ill do some more driving with it to see if anything is out of the ordinary.

If worst comes to worst ill part it out. Ideally i wouldn't because I have a few cars coming my way but I gotta do what I gotta do.

Ill probably be doing that.
