Hi,
I remember I lost all Ncs expert code setting when i changed battery a few years ago, I had to spend hours to recall and recode my car. I am planning to do a steering wheel swap this weekend so i need to disconnect the battery to remove airbag. my question is is there a easy way to save my Ncs expert coding instead of save individual ecu file module by module? becaue i did a lot of coding to different module. i can't remember all of them.

Coding does not disappear from the car if you just disconnect the battery .
Coding only changes if the the module files are overwritten such as
what happens when you take the car in and they update the software.

When you do the first Ncsexpert setup it makes a master file of everything
in the car it's up to you to save it .
It is always a good idea to keep a copy of any changes you made to a module.
And save it to a Man file with the appropriate name.

Thank you ctuna,
maybe a certain period of time is ok, but after a long time without battery the all coding including all console settings all gone.

I've had the coding reset on me one time after pulling the battery to install a steering wheel. Really weird. It doesn't always happen when pulling the battery.

I pull my battery for ~6 months storing my cars (keeping them inside with a trickle charger) and no coding has ever been lost for me.

I doubt any longer would make any difference
