Hi! My C230 has 80,000 km. It runs fine, but 2 months ago it started stalling at stop lights (4 times) ,while driving (1 time) and 5 times wouldn't start after parked for a short time. It always starts after sitting for awhile. I've taken it to a Mercedes Service shop twice and they can't fine any codes to determine what the problem is. Of course it runs perfect for the mechanic. Please Help! Thanks! George
