After starting engine, around 20 secs warning comes that right rear brake not working, right rear parking light not working. But there is no issue with brake lights or parking lights. Physical inspection shows it works just fine.

Possible ignition switch issue: I was driving on the highway at around 70 mph when there was click sound accompanied by loss of power, brakes didn't function properly, steering wheel became increasing hard to maneuver. I was able to bring to a stop by the shoulder. I noticed that the ignition switch had got turned off. I turned the ignition and the car starting working again. Very scary!

This complaint pertains to Audi adblue(nox) system. We recieved a fault on a road trip. It stated car would not turn on within 600 miles. It started to count down. After 3 dealership visits they informed me that the first part to replace is a nox sensor to the cost of 1300 dollars. I refused as I didn't have that amount. So now I have a car that cant be driven because it wont turn on and comply with federal emissions. I feel that if there is a part having to do with federal emissions then Audi should have to be forced to replace it like they would a catalytic converter. Or not disable the vehicle in case I'm in the middle of nowhere!!!!!! Audi should remove that programming, given the fact that in a state of emergency I would appreciate the ability to continue driving for months or years(if need be) if the country is lacking infrastructure. Another scenario would be if I decide to drive all the way to the southern tip of South America. I would hate for my car to be stranded because of a not so critical issue.
