I am interested if anyone here has had a similar problem. I have a 2020 Touareg Rline tech, I bought new in March and it came fitted with VW tow bar etc. I bought it for towing my Caravan that weighs in at 1630kg. I am very pleased with the car, it does everything I hoped it would do HOWEVER, when towing, after 1 - 1.5 hours the ACC throws up a fault and stops the safety elements like lane assist and front assist etc out. This is due it seems to the sensor for the ACC realising that it is pointing skywards and unable to function properly so as a fail safe it shuts down. Once you stop towing after circa 30-60 miles the system resets and works fine until the next tow when the same happens. This fault occurs regardless of whether you use the ACC or not. Clearly the local dealer is aware of the problem but is at a loss as to what to do. I am currently working through the problem with the dealer to try and resolve this issue, I have read elsewhere that an individual took his treg to the dealer who firmed up the rear suspension and reduced the sensor sensitivity!!!! Thats a cover up and not a cure. I can see this problem rumbling on for ages or until VW get a software fix but I am curious if anyone here has or is encountering a similar problem. The dealer is aware of the problem. I guess if the dealer cant sort it then VOSA and Trading standards are the next stops. I didnt really spend a lot of money on a car that boasts being able to tow a 3.5 ton trailer when it cant tow very much without losing it main safety feature?
