EA189 Rollback

Hi, I hope this is posted in the correct place.

I am looking to get a rollback on my VW Caddy 1.6tdi dsg, but the tuner has had trouble locating the original files on the ECU or his database (wiped by VW no doubt).
The ECU label is of no use either as it just shows the number 03L-907-425c, which is the hardware number according to the coding.

Is there any way or place I can retrieve the original files?.

Address 01: Engine Labels: 03L-906-023-CAY.clb
Control Module Part Number: 03L 906 023 TK HW: 03L 907 425 C
Component and/or Version: R4 1.6l TDI H43 9977
Software Coding: 00254014032500080000
Work Shop Code: WSC 35110 790 50316
ASAM Dataset: EV_ECM16TDI02103L906023TK 003001 (VN35)
ROD: EV_ECM16TDI02103L997557M.rod
VCID: 025E838A748E7EF7DCD-8056

Many thanks Steve

It's in the current Volkswagen flash disc available to everyone, according to this: https://vag-flashinfo.de/index.php?partno=03L+906+023+TK+&as=
The tuner should have no hazzle flashing back the ECU to stock firmware with this.

Thanks for your reply

The only files on this site for my software number are all files post Vag emissions fix. I am looking for files pre emissions fix i.e. earlier than revision 9976

It should have had another software part number prior to the emissions update. Just check your old Auto-Scan logs. The TK in "03L 906 023 TK" came only after the update as far as I am informed.
