02 2.0tdci do identical injectors need coding? - carnut1980
my 02 mondeo tdci 130 is still showing the same symptoms even after i changed all 4 injectors. Noisy on idle and underpowered. the glow plug light is flashing and a p2337 code showed up on diagnostic. I replaced all 4 injectors with exactly the same part no.s from an identical car, but still no difference. Is coding the answer, or is coding only needed if the injectors have different part no.s?
cheers

02 2.0 do identical tdci injectors still need codi - adverse camber
Coding still needed I think.

As I understand it the coding compensates for the fact that even nominally identical injectors actually behave slightly differently. The flow rates etc.

As injectors age and wear their performance changes - which is why recoding is recommended sometimes on old injectors.

With older injection systems there was no big deal about small variations, however modern high pressure systems do not just have a single injection per cycle, there can be 12!


In fact, I asked about this a while ago :
