Help - Screwed up ACC trying to fix Lane Assist.

[ForeverAlone200]

I bought an used 2019 Q5 with ACC, Lane Assist e Traffic Jam Assist.


Lane Assist and Traffic Jam were not working. The autoscan gave me erros in 13 and A5:

So I went to 13 > Output Tests and did a reset. That stupid move just screwed up everything. Now ACC is not working either, autoscan is showing errors in 01, 13, 15 and A5:

Dealer wants $700 to fix everything.


With VCDS, I tried to reset the dynamic learning in 13, but it gave me "error: channel not available".
With OBDEleven I can do the reset, but as soon as I turn off and turn on again, same errors in virtual cockpit ("ACC with Traffic Jam not available", than "Lane Assist not available", than "Pre Sense not available").


I got a cheap Godiag J2534, but have no idea on how to try to fix this with ODIS-E. Can anyone teach me me some steps?

Did you noticed some how that the coding was changed , cause i think its a coding issue .try this coding on both adresses 13 and A5
