The brake guard was turned off in all instances. The dash warning chime/light came on and instantly the car carried out an emergency stop. The car went to the dealer to have this checked out after the first time. The dealer could not find a fault code or could tell if the system had been activated. The Master Tech told me that for both front and rear systems it was impossible to tell if they were working properly until the car has had an accident. He said that this was known at the Audi factory and was a grey area in diagnostics. We also established that no fault codes are provided by this system.MikeFish wrote:As I stated in the other thread and posted a photo of my MMI, I'm pretty sure the crash mitigation you are talking about is the Braking Guard that comes only with the Assistance Package. And my MMI has an option under the Braking Guard heading called System which I can turn on an off. Just thought I'd reitterate in case anyone else reading this finds their car carrying out emergency braking for no reason then to look in their menu and see if they have this option and try turning it off.RSllama wrote: After 7 months I had enough and rejected the car in July 2016 on safety grounds. The car was downright dangerous as the crash mitigation system was faulty. The radar/camera would think the car was going to crash and it would go into lock down and then perform an emergency stop. As a driver you have no way of over-riding the system.
I assume whne it happened to you, you got the brake guard warning on the dash? Just wondering if it was the brake guard activating or the brake assist coming on.
Regardless of this the car had/has 23 other faults for which I only know of 1 that has been fixed (DRCs) and that is a temporary fix as Audi has stated to me that the operating noise (knocking) will never be entirely eradicated. They have stated that whilst the modified struts will quieten the noise, the knocking will come back once the struts have bedded in.
Safety related issues apart from the brake guard/brake assist/crash mitigation failure are: headlight beam assist, parking sensors, speed display, park assist and complete brake failure. No safety report was ever produced (automatically carried out by the dealer if there is a breach of vehicle safety, as stipulated by Audi's working practices). This was queried by Audi UK at the time and in my ownership, never retrospectively carried out.
