Just a quick update on my case — I picked up the car on Tuesday. All the repairs, including diagnostics, were fully covered under the 7-year extended warranty. The newly installed BSG also comes with an additional 3-year warranty.
To my surprise, when I collected the car, I found a generous gift box from Audi in the boot. It included jackets, a hat, a bottle of Moët champagne, air fresheners, a backpack, a cup, a key ring, a cleaning kit, and a few other thoughtful extras.
Overall, Audi really stepped up and handled the issue to the standard I expected. I've learned my lesson and decided to take out the extended warranty plan with Audi — better safe than sorry!
All in all, I’m pleased with how everything was resolved and back on the road with renewed confidence.
