Hello Adithya,
Thanks for coming back on this.
My ‘standing’ on this forum is really no different from most other members, except that the moderators generally have more than a few! posts behind them, and are untrusted to act with respect and uphold the best interest of the forum.
I am certainly not employed by Audi, and indeed it’s been a couple of decades since I was employed by anyone. Some will know that!
Discounting my own contributions, we are fortunate to have a core of contributors who are prepared to offer their best advice, and I think it’s fair to say much of this advice is based on shear experiences of issues - with Audis and many other marques.
Quoting me, will get you absolutely nowhere, but I stand by my opinion - and it can only be an opinion until proved or disproved - that your issue is associated with a below par battery. This opinion is supported by the now additional warning re cruise control, and as the battery becomes even less efficient (if - in caps- it’s all to do with battery efficiency) you are likely to get more and more warnings coming up, and eventually encounter the ‘Christmas tree’ warning light array.
One of the parameters that can become substandard is the cold cranking amperage, and the stop/start will shut down because of the perceived risk that the car will not restart. There will of course be other parameters measured by the BCM.
Apologies if this has become boring.
Kind regards,
Gareth.
