Thanks for the info, however I fear the the latest C8 A6's have extra Nanny controls as standard.
The car is a 2021 A6 Black Edition with Tech Pack.
I have had Lane guidance on other cars (including Audi, VW and Jaguar) and have been able to set the lane guidance default to OFF.
However, their seems to be 2 systems on this car. 1. Lane Guidance warning, and 2. Lane Departure.
1. Lane Guidance warning. I can turn off on the MMI under 'Drive Assist' This is the little vibration warning when you approach the edge of lane. TBH I could live with it albeit a little annoying after a while.
2. Lane Departure. This defaults to ON every time you turn the car on (regardless of turning OFF Lane guidance warning in the MMI). This is where the steering is actively controlled and turned in when you approach the edge of lane. This cannot be turned OFF (from what I can see) in the MMI. As far as I can tell the only way to turn this off is with the button on the end of the indicator stalk. It then defaults back to ON when you restart the car.
I really don't like this 'feature' and would like to find a way to turn off longer term. I get that there is a place for it, usually long stretches of A roads or motorways, but I rarely travel these roads so will spend more time manually turning it off. Not the end of the world, but I've managed 30 years of driving without it and would rather to stay that way.
