Evening all, I’ve just bought new injectors for no 03 E55 W211, my original injectors are black, but these are light blue (Bosch 62717) which from what I can gather are the replacements but have slightly bigger capacity. My question is do I need to code these (I’ve got the latest icarsoft) if so there are two sets of numbers/letters on the box, one 6 and one 18, any ideas. Also what’s the best lube fire the o rings, petrol, engine oil, vasaline. Any info or tips gratefully received. Matt.
