Good morning , update and advice please. The A1 finally broke down in February. Had the injectors tested and three failed. Note it had four injectors new in 2022 and only done about 10k before they have failed. 😞 anyway to test the car we have fitted four used injectors out of a scrap car. My question is without the information to code the injectors in to the A1 how long will it last before a light or fault code appears ? As there are no numbers on the injectors.
cheers
