salomè

I have a C180 Classic 2001 model. It starts perfectly, then after about 50km or so, the engine just dies on me. It mostly happen on warm days. The car starts immediately again and if I accelerate it doesn't cut out, but the moment I take my foot of the petrol, it dies on me again. I have taken the car to a Mercedes mechanic, but says that his computer shows no problem!! Can anybody please help??
