Hill Hold Control VW Touareg: High Mode?

Hello,

My Touareg already has the Hill Start Assist (HSA) feature.
However, unfortunately, it only works in 'LOW' mode (gear ratio).

According to another forum, it is possible to do this with VAG-Com.
to be able to activate the BAH even in HIGH mode.
Unfortunately, no one writes like that anymore.

Can you help me with that?

It probably needs to be adjusted in the ABS/brake control unit.
but I can't find it.
My ABS/brake control unit is the 7L0 907 379 D.

I have the air suspension with leveling control and the 6-speed manual transmission.

Sure, here's the translation:

'Thank you in advance.'

Regards,
Marcus.
