Golf 4 Dashboard: Complete Instrument Cluster

Hello,
I have a Seat Leon, manufactured in 2001, with a 1.9 TDI engine (engine code: ASV, 110 horsepower).

"I've now installed a speedometer from a Golf 4 TDI with FIS (multifunction display), and everything is working perfectly. Pairing the immobilizer and keys wasn't a problem. However, I'm having an issue: the airbag warning light is on, and the error code is as follows:"


Control Module Part Number: 6Q0 909 605 A
Component and/or Version: 1L AIRBAG VW5 0A 0004
Software Coding: 12620
Workshop Code: WSC 06441
1 Fault Found:
01299 - Diagnostic Interface for Data Bus (J533)
62-00 - No or Incorrect Adjustment


Do I need to reprogram the airbag control unit? Or is this error unfixable?

Best regards,
