New to this but I’ve had to replace my 4 injectors as the their either dead or near to death as their the cars on 174000miles. When I looked at the part number on my old injectors, they were of 04L not 03L. The picture is of the injector which came out my car. I rang a breakers yard and they told me it’s the wrong injector and that my code is 03L. I’ve ordered a new set of injectors with which are the same as the picture below but I’m concerned due to also checking online that they are not meant for mine but were working perfectly for the however long I’ve owned the car. Any help would be appreciated thanks.

Well I suppose if they work and have done for that amount of miles then they should be good to fit.

Not sure if you have to code them in though?
