Sprinter 311 edc light cutting out & limp mode
Hi new to this forum but already very helpfull and hope some one can help me further .
My Sprinter is a 02 311cdi with 320k on the clock since buying it 5 years ago it has always gone into limp mode on a morning going upthe hill from my house ( no edc light ). never really worried about it as I have drove a number of sprinters and most of them have done the limp mode thing a lot worse than this.
Last year it got worse and worse untill eventually cut out and wouldn't start. After a number of Ideas including tank off cleaned fuel lines blown back to tank,filter change, pipe leading from filter to pump, the return valve on filter top change, it was found that the seals on the back rail pressure switch were to blame . 12 months have gone by still had the limp mode problem but useable . every now and then it would cut out edc light on . now its got to a stage were it cuts out every five minutes but always restarts (seems to do it more when I need the power i.e on hill . Infact it cuts out exactly were it used to go into limp mode. I have changed the rail pressure switch totally (not just the seals) with a new one but just the same .
Has any one got any ideas for me .
