Hello and sorry for this stupid question ...but i'd like to receive more info about real meaning and real differences about these maps CD, CW and CLA.

I know they are code word, error class and configuration byte... but which one is only the DTC in vag? which one is the real sensor function? When is it better to use one or the other...or both ?

I'm asking this becouse neither english neither german are my main language...and it's time to understand well what they are and not only apply becouse there's written in the tutorials

Regards
