New Injectors, 5000Kms on, do I still need coding?

[dsaran]

Hello,

2009 3.0TDI quattro.
I replaced all six of injectors with brand new Bosch 5000 Km before. I am not sure coding was done or not at my local mechanic.
Do I need to do "coding the injectors" now? And is there any VCDS/VAGCOM checks that verify the injectors work normally or not?

Thanks in advance.
