My tuppence worth. Problems with the 25MY B10 are well documented and although it shouldn't happen, and in my opinion should have been addressed before the 26MY was released, to Audi's credit, they have acknowledged the software issues. It's something I would have been able to ( and still am ) reject the car. Outwith the software issues, my car came with a couple of faults - sticking brakes and an annoying rattle from door panel, both of which were rectified at dealership. That can happen to any car regardless who the manufacturer is. A smearing windscreen wiper typically means both the rubber and the glass need cleaned. First thing I've done with every VW group car I've owned is replace the wipers with Bosch aerowipers, but thus far it's never been required with this A5. (They look very similar to the Bosch ones) Software: I don't get as many system failures since the 'open/close' door solution but I'm led to believe that the software fix for MY25 is now being rolled out - EV cars this month, ICE next month. You should be notified via My Audi app when the update is available. It'll require a dealer visit. Regarding the battery. Welcome to modern cars. Our other car is a Toyota hybrid, one of the most reliable cars on sale. That too has already undergone a battery replacement due to the battery management system. The 'fix' if you can call it that, is the car now notifies me when the battery needs attention and the car has to be driven to charge the battery. Modern cars don't seem to be able to cope with sitting doing nothing for 2 weeks as they're constantly monitoring themselves. If you're knowingly going to leave the car sitting for several weeks or more then best solution would be to put it on a trickle charge. That goes for any modern car but especially for those that you're able to communicate via a mobile app. Hope that's of some use.
