DSG交換前後のVCDSスキャンデータの比較をしました、

「Address 02: Auto Trans」辺りのどこかが変わっているかと調べたら何も変わっていませんでした。

その代わり下記が変わっていました、

Address 01: Engine (CAV) Labels: 03C-906-027-CAV.clb

　(略）

Readiness: 交換前：0000 0000　交換後：0110 0101

Ross-Techの説明では

The Readiness Code is a set of 8 bits, each of which corresponds to one monitored emissions "system" in an OBD-II car. When all readiness bits show "Passed", it means that all systems have been checked and have passed the on-board tests.

Whenever you clear DTC's or remove power from the ECU, all readiness bits will be set to "fail". Most cars do not have all 8 systems, so as soon as you apply power again, the bits corresponding to systems that are not actually in the car will come up "Passed" again.

It takes a variety of specific driving conditions to "test" all the systems. It can be done in a short time using a very specific and complicated procedure found in the On Board Diagnostic section of the Factory Repair Manual for your engine. The alternative is just to drive the car for 2-3 days. Make sure you include at least one short highway trip, and your Readiness Bits should all read "Pass" again.
