ok, i just broke down again in the 240d. what happends is, im cruising along(always on the highway) and the car starts to deccelerate, then dies, i can start it, then it dies again, like it is starved for fuel this has happened before, ive changed the fuel filter, and its fine. its been about 2 months since i last changed them. how long is normal between changes? I am not sure if this problem is bc of the filter or something else....I dont think the car should just stop running like that, no? thanks!
