hi im new to this site and hopefully i can get some answers on my car.. i have a 2009 520d.. i was driving it and it went into limp mode so i turned it of and it failed to restart. had it towed to a garage and they said i need a new diesel pump had that fitted then they said it needed new injectors. had all that done collected the car and 10 miles down the road same happened. they said it was no1 injector again. had another put in and same again has happened.. what could be causing this problem or is it not the injectors thats at fault are they just saying its the injectors.
