Sorry - doing this from the phone and hit the wrong part of my screen. What I was going to say was be sure to check your battery connections. Make sure they are very clean and tight. Also, can you give us an idea of how old your battery is? Is it a white "Varta" battery? I've seen some reports of the cars doing goofy things when the battery is on it's way out. Even though it will still start the car, it can still cause little problems if it's weak. Just trying to get some info listed so the other members can chime in and help out.
