Camshaft sensor issue

So my check engine light came on. Plugged in my code reader and it says it's the camshaft sensor. I'm thinking it may also be the vanos. It's a 99 e46 323i with only 88k on the odometer. Do you all think I need to address the vanos now, or can I get away with just replacing the sensor for now. The sensor should cost about $89 + shipping. Rebuilding the vanos seems to be around $500, with parts at around $150. I would rebuild the vanos myself, but I'm a bit intimidated and don't want to screw up the car. I wonder if i keep driving with the light on if it will cause further issues for now.

Your assistance is greatly appreciated.
