Park Assist Error after Can Gateway upgrade from Version 1KO 907 530K

[Gizmo WV]

Hi Everyone

Having just joined the forum, I am hoping some nice person will be able to assist with an upgrade just completed from 1KO 907 530K to 1KO 907 530L - installed on our VW Touran 2.0 DI Sport 2007 due to parasitic drain on battery, after retrofitting RNS 510 version C with 5238 Software

I finished installing the Can Bus Gateway half an hour ago, having printed each screen to be able to programme the replacement gateway with VCDS 17.1.3, after a drive round to clear Wheel Sensor, I have an error code, for what I believe to be PARK ASSIST (76)

The error is as follows:

1KO 919 283 A

05 Einparkhilfe 0101

Fault

01299 Diagnostic Interface for Data Bus (J533)

005 No or Incorrect Setting/Adaptation

- - - - - - - - - - - - - -

Park Assist (76) is ticked as per the print screens, no other faults/errors are showing

There is one other thing, I have lost all streets in Navigation since the upgrade, presume I will have to reinstall to correct this - IF anyone knows better than me, then I will bow to your knowledge.

Thank You in advance for any help you can afford.
