PaulN Posted December 2, 2010 Share Posted December 2, 2010 So - does this function only with the EGR - or does it have a function to control the cold start advance facility on the Bosch pump head ? Uh Oh!! Sounds like a problem looming! Better look and see if my 300's got one - if there is, no-one told it that the EGR valve's gone!!
