D3 injector codes?

tyregeezer · Aug 4, 2023

Hi all does anyone know the difference in the last two letters of injector part number ie. 4h2q546cb had an injector leak but only have a 4h2q9k546af which have fitted, not coded unsure about that only ever taken them out and put the back in where they came from, no leaks runs fine ordered a CB just now but have seen several different end 2 letter code all state 04-09 can anyone enlighten me?

04 to 56 is euro 3, 07 to 09 is euro 4, and I believe the euro 4 injectors are different as they run higher pressures.

No need to code, I just slapped new ones in mine, but previously had moved some around to try and cure an unstable idle issue.

I have 6 used and one nearly new in the garage if you want me to check numbers?

Thanks is yours euro 4 if so would be interesting to know your part number if you don't mind only the last 2 letters are different between my 07 and 09 thanks again

I think mine is Euro 3, 07 onwards is Euro4.

Would still be interesting as my 06 euro 3/4 has indistinguishable part numbers on the injectors.
only differences between 07 and 09 are the last two letters on the part number but again most ads say 04-9 etc so just trying to get a better idea of what fits what also have a set of jag s type injectors which are different also twin turbos I suppose but would appreciate the number when you get a moment many thanks
