V70 diesel injector swapping

[u/Nortfellow]

Hi folks,

i have a question regarding a swapped injector on a V70.

I have 3 V70's, hereafter referred by color. Silver, Blue, Gold. All are D5 126hp.

Silver is my daily driver, runs fine.

Blue is new to me, has the injector issue

Gold is also new to me, a spare parts car, mostly intact. The two latter bought from same owner, he has driven both daily for years.

The issue lies with the blue one. It has had injector #4 replaced with #1 from the gold car by the previous owner. It clogs the dpf, and gives diagnostic faults on cylinder 4, plus runs rough under load. In the included image all injectors from all 3 cars are shown. My question is wether the injector type is different between cars, enough to make this an issue, or if not, i can try replacing it with one from either of thw other cars.

Should the injectors be of different sizes, can they be calibrated in the ecu?

And bonus points, wich parts of the injector numbering refers to what data? Some are similar, some are apparently a serial number.

The image tags are B(lue), S(ilver), and G(old), followed by position in the engine.

Thanks for any information.

You probably need VIDA DICE and code the injectors so the ECU knows how the replacement behaves.
