Ok, so I just picked up a 2006 x5 3.0 with 74k on it. Wonderful condition. California car.

Driving yesterday, the check engine light came on while I was playing with the computer button. Checked with scan tool and said it was an o2 sensor. Cleared code, now nothing and no pending codes.

Next, I had a tail light out. Replaced bulb but then later computer said it was still out. I assume I needed to do a computer cluster reset, which I did.

Today, airbag light came on while in idle. Did another reset and seemed to clear.

Is there something else I should be looking at?
