I currently own a 2001 MB C320 4dr sedan. I love the car however I have 2 major problems that refuse to go away.
1) The battery drains if the car is not driven in 8-10hrs. What could be the cause?

2) After getting a jump from my roadside assist, I found out that my wipers, turn signal, fuel gauge, remote trunk release, and my alarm don't work. The message displayed says Display Malfunction with a zigzag arrow on it. I checked the fuses and everything is o.k. Does anybody know a remedy or fix for these problems. It is pain driving without this things. The dealer wants an arm and a leg to diagnose. Help????
