Hi there I'm new to this site and I'm looking for some advice. I had a strong smell of diesel inside my car coming through the fans. I removed the engine cover and I noticed a puddle of diesel around the 2 middle fuel injectors, so I took it into a local garage and he told me that it's most likely the leak off pipe that need replacing. So I've brought it and put it on and the leak is still there but I cant see where it's coming from. Anyway my question is that my Haynes manual says that if I put in a new fuel injector I need to have the serial number so I can program it to the ECU? Is this correct? as I dont mind changing it but wont be able to if the ECU needs programming.

The parameters of the injectors are stored in the ECM, the 11 digit code relating to the injector characteristics.

The engine will run fine if you don't have the facility to program the injectors, however it won't be at optimum performance, but in my experience, most owners would likely never notice anyway.  Hyundai Ioniq 5 Ultimate. The family car.

Any use to you?
