N47 Injector Replacement DIY

Has anyone replaced injectors? If so tips? Also is it hard to code injectors? That is the part that I am concerned with. Thanks!

The physical replacement is easy, 15 mins each, tops. They pull out by hand.

Be extra careful with the fuel return clips on top. They can get fragile and break. Simply clean the bore if it's dirty, do not grind or anything invasive like that!!!!
Original injector is lubed on the outside with some grease, you should do the same.

Coding depends on what tools you have. It's as hard as typing in a few numbers and letters.

Will be doing this soon as well given the 24BB00 code I just got today. What coding is involved to recalibrate the new injector?

It's basically a registering the new code that is inscribed on the injector body, into the engine ecu with BMW diagnosis software.
Usually you can use ISTA-D or even Tool32.


Some mobile diag apps may do it too.

Thanks for the input, looks like a relatively simple process for coding. Any idea if this can be done in BimmerLink/BimmerCode? Otherwise looks like I need to get set up with ISTA-D

*EDIT* contacted BimmerLink support and this function is not supported
