Hi there my name is Diogo, I'm only registraring now because now it happened to me. My c220cdi w203 2004 had what is called a diesel runaway. I've seen it happen to a member before and iI' like to now the answer to my problem. As it happened to that member my engine turns but it won't start. What can it be? Sorry for not posting it in another area but imI freaking out!!
