Having thought about things overnight, I am seriously p1ssed off at Audi's response to all of this so penned them the below email copied to the Audi UK Customer Service Director. I will let you know what they say.

Having reflected on matters overnight I am really not happy.
Having suffered a catastrophic brake failure on Thursday nearly resulting in ploughing into the back of a stationary car on the M1 at 70+ mph I do not think the response from Audi is acceptable.
I cannot fault Audi Assist - a roadside technician visited promptly, a replacement car was organised the same day and a flatbed truck recovered the car to your dealership first thing on Saturday.
However, following several futile attempts to contact your service department yesterday, I finally gave up and went in there. The response was far from acceptable.
Personally, if I was presented with a brake failure, particularly on an RS product, I would have stripped that car down on arrival to identify the problem in case a wider recall was required. Instead, I was told 'we have 48 hours to look at it, Saturday doesn't count, so we will look at it on Tuesday'.
As a person supplying these cars are you satisfied with that as a response?
If Audi Watford consider brake failure on a RS car to be a standard issue and dealt with as a low priority item then they are not fit for purpose.
I expect a full written diagnostic of the fault and it demonstrated that this is not going to happen again with a replacement part.
I also expect a call from someone in the morning to confirm that this is being taken seriously and will be dealt with as a high priority given the wider safety implications.
