Assistance with DIY Haldex Gen 4 Firmware Update (2K0907554D 5010 to 5011)

Hi everyone,

I'm looking for some technical guidance regarding a firmware update for the Haldex unit on a 2014 VW Caddy 4Motion.

While performing a scan, the following details were identified:
- System description: Haldex 4Motion
- Hardware/Software number: 2K0907554D
- Current version: 5010
- Target version: 5011
Protocol: TP2.0: KWP2000

Since standard diagnostic tools like OBDeleven only show the update but don't support flashing, I’m looking for advice on the best path forward.

Which tool would you recommend for this specific flash (VCP vs. ODIS-E)?

Where can I reliably find the correct flash file (FL_2K0907554D__5011.frf)?

Are there any specific Adaptation or Basic Setting steps required immediately after the flash for this Gen 4 unit?

Any tips or technical documentation would be greatly appreciated.

Thanks in advance!
