E83 fault codes P0335 and P1727

This morning my low oil light came on when I started my x3 but then went out once it warmed up and I left for work. When leaving for work and trying to start up it cranked for 5-10 seconds (this has never happened before, always starts right up). Then I had multiple lights on such as check engine, 4x4, and then the brake light also stayed on after taking off the brake and all lights were orange. I decided to try to drive home about 3 miles and the car mostly acted fine but I didn't push it and took it easy, very low rpm's. once home I checked everything and the oil was low so I filled it (I use Mobil 1 full synthetic 0w40 and it does burn off a bit, hopefully that isn't a sign of a major problem. I would say I have to add about .5 qt after 3-4k miles then I change it at about 7k miles). I also noticed I was a little low on coolant so I topped that off too. I started it back up and it fired right up and ran fine but check engine was still on so I went down to the auto parts store and had the codes read: P0335 - Crankshaft sensor error, and P1727 which I believe is a no-start error. I drove back home and the check engine light went out and the car seems to be running fine. In reading over some other forums tonight I'm not sure if I should do something else at this point. Should I replace the Crankshaft position sensor? or should I just wait to see if it happens again? could low oil lead to throwing that error code?

One other thing is I noticed a bit more buildup under the oil cap than I think was there before.
I recently changed locations where I work and instead of driving 30-40 minutes (18 miles) each way, now I only drive 3 miles and about 10-15 minutes and nothing faster than 40mph to work. I have read that in the cold months this can cause condensation buildup in and around the oil cap but could that be related in any way to the error codes?

It's cold and my garage is full so I'm hoping this doesn't turn into a long freezing weekend for me under the hood.
