AWD DSE malfunction error & ELV electronic steering wheel lock error

What is your question?

We recently purchased '06 530xi with 103,000 miles. In back of owners manual we found a note samtaring the car had AWD/DSc error AND ELV error. It was dated 1/6/16 with a note saying Do not buy this lemon!!! Of course we are now concerned! We have not personally seen this message. I've read online it could be glitch due to bad battery. Dealer did say battery was just replaced.. Any advice? Is it worth keeping or should we trade it in for another car.
