Hi all. I just purchased an allroad 2004. No owners manual came with it. Today a light came on. I've only had it for two days. It looks like an exclamation point inside of an octagon type shape. To the side of this are three wiggly lines. Any idea of what this is? It has 90,000 miles on it. Thank you.
