Hi,
I was reading the forum, but I just could not find an answer to my problem. I just bought a 2001 C240 with 83,000 miles. I am in Orlando Florida. Everything was fine until the weather dropped into the 40's and 50's. It takes me a while 5 to 10 minutes for any of the keys to unlock the doors, and once unlocked, it takes me another 40 to 50 minutes for the car to start. Initially the key won't even turn, after 10 or 15 minutes it will turn, but the car won't start. after 20 or 30 minutes, sometimes even longer of turning the key it will start. In the mean time the panel is going nuts turning all the lights and display on and off. Once the car is warmed up, problem gone until next morning. I also have the SRS light on. Please help me since I have to go to work every morning and I am having a hard time sleeping by thinking if the car is even going to turn on in the morning.

Thanks,
Ray

 

if the battery is old replace it. thats the first thing. weak battery in a benz can cause weird stuff to happen. check the battery terminals and make sure they are tight.
