Tutorial: how to replace Gateway MQB High 5Q0907530AF with another MQB High 3Q0907530AC.
General procedure:
1. Make a backup of all codings and adaptations via ODIS-E
2. Replace Gateway with 3Q0
3. Restore codings/adaptations, load parameters
4. Remove component protection (CP) – buy access for an hour
5. Restore SWaP codes
ODIS Adapter:
The adapter used is the red VNCI 6154A interface.
Next, select the Gateway. Having searched for different options for AA/AC/AG/AR, some nuances with versions/manufacturers appeared: incompatibility with 3q0 radars (especially when you have 5Q0), a problem with the generator Lin bus falling off.
Problem with the generator, possibly due to incorrect parameters.
Choose 3Q0907530AC for two reasons:
1. There is a dataset on mibsolution 3Q0907530AC_Superb_3.xml
2. This was already installed on the 2016 Superb
Found a used Gateway Lear 3Q0907530AC from Octavia, the seller said that everything was legal and would connect without any problems.

1. Gateway is located above the brake pedal and can be easily removed. We install a new one, launch it and everything falls into the protection of the components.
The dashboard is flashing, a lot of errors.
2. Connect through ODIS to restore the coding.
3. Through WinMerge I wanted to see the difference in adaptations and restore everything in ODIS-E, but at the very first point I got stuck, i.e. To. ODIS displays values, not keys (so to speak)
I don’t know how to find [LO]_Node_0x09.
Having looked down a little, I figured out that I could upload it there (In block 19 you need to double-click on “046 – Special vehicle functions”) from the backup: both coding and adaptation. Because I have already restored the coding, I am restoring adaptations.
in the new block some adaptations are different, so not everything is restored.
Fill in the parameter 3Q0907530AC_Superb_3.xml (010 – Data transfer -> 010.01 – Write data block)
4. Component protection. I bought access for 1 hour on online geko for $25.
We run diagnostics in VNCI 6154A ODIS-S, a bunch of errors appear in the Diagnostics Plan. We launch 19 – component protection, when it asks for a login password, click IMMO-CP, everything is inserted automatically and just follow the steps. During the process, the key will need to be kept near the Start-Stop button.
5. Next, restore SWaP codes.
In the same place in ODIS-S, go to Special functions – FFS function unlocking system
Enter block 19, again asks for a login password, click on SVM CODING.
According to my plan, everything should have ended. But errors appeared on the generator bus and shutdown upon impact.

I decided to try climbing in Basic settings through software. First, I removed errors in the engine block and gateway. Then in block 19 I carried out “generator: recognition of a family of regulators”.
And after that there were no more errors.
