We have a 2020 A4 progressive S-Line with 30,000 kilometres. Travelling at any steady speed between 60 and 120 km/h there is an annoying noise coming from either the wheel or behind the speedometer /tach. It's pretty subtle but annoying as the car is so quiet. It sounds like the old days when a speedometer cable was either broken or needing lubrication. I may take it into the dealer in Victoria but having them drive it around the block will probably result in "We can't find anything wrong" Has anybody got any ideas as to what it may be? Appreciate any assistance as it is driving me to distraction....
