On my 2019 model Touareg R-Line the Adaptive Cruise Control and associated functions has an intermittent fault - in that it stops functioning. The dealership advise that there is not a "software fix" available from VW! I HAVE BEEN UNABLE TO GET A RESPONSE FROM VW UK as to when and if this will ever be repaired. This has been going on since October 2019. Are there similar problems elsewhere?
