Just got the Q3 new. When I use the ACC on a motorway the car slows down when moving past slower vehicles on the inside lane, really annoying and dangerous as it just starts to brake. Its fine on single carriageways. 

 

Any ideas?

Hello Phil,

Thanks for being in touch. Not wanting to be unhelpful, but the answer to your very valid concerns rests with the supplying dealer, and obviously must be covered by the warranty. 

If this were mine, I would be booking this is for investigation and asking for a Covid-acceptable road run to demonstrate the issue. 

Perhaps you would be kind enough to come back to the forum to let us know how you get on. 

Kind regards,

Gareth. 

Well, we have just moved to Germany. We travelled through France with the cruise control on and no problems at all like we had before in UK. Looks to me like Audi have not fitted the correct (or installed wrong software) for the sensors for UK use!!

That's not good! Hope Audi Germany are rectifying this for you
