Software Update By Dealer

[andys]

I'm waiting for my van while it's being serviced and I've just been told there's a recall which will involve a software update. I anticipated them resetting my changes and took another backup on VCDS last night, but if the software is changed will I be able to just copy and paste my old code back in, or could some of the memory addresses be in a different place now?

In answer to my own question, absolutely nothing changed. I was surprised to find that even after the software update, the changes I made in VCDS have remained untouched and I don't need to do anything.

The information of software/firmware version is located at the end of fourth line ("Component") of VCDS Auto Scan (see the examples below). That reveals what module has got the new software. However, I’m not sure how relevant is the “Revision” seen on some modules.
