Hello Sprinter-Spezis, since my 313 CDI is a bit annoying to me because of its unwillingness and I need a quick solution (also because of lack of time), here the question in the round, if something speaks against, if I turn on the glow plugs by hand by means of push buttons and extra relays, i.e. glow relays and what else is in it except bursting. My question is above all prophylactic, if I do not find on the fast the error and not the right parts Glow candles are new! Thanks already in advance!
