Hi i just bought a Stelvio 2019 and found that when using the towbar the parking sensors rear will not disconnect. Bougt Ecuscan with multiplexer. When connected to Bosch parking aid it was coded as no towbar. I altered it to towbar and close program. But it will not work! Same as before, now coded as towbar present. I also see if it was possible to alter in central electric modul but no option.
Need help!
