Indirect TPMS with MK70 ABS

Hello Folks,

I've received usefull info and tips here, how to active indirect TPMS on my FL O2. Now it works, thank you all :-) .

So I decided to activate TPMS on my fater's car, since it's a bit similar to a pre FL O2. He has a mk5 Jetta with MK70 ABS pump (no ESP, only ASR and ABS).

So in the ABS coding menu I set the long code to 641 (==Jetta MK5, 7K6 TMPS).

Now the TPMS icon is active, it's blinking. So I went to the Basic setting's 042 group in the ABS menu. According to Rosstech, I should reset the TPMS here. But even if I press the ON/OFF/NEXT button nothing happens. It shows, that the TMPS is enabled, but the Reset status is solid N/A, I can't change it.

Do you have any idea, why, can't I reset the TPMS via VCDS?
