Glad the dealer acknowledged that the tires have flat spots and offered to replace them. Your A4 must came with Pirelli Cinturato P7 tires and the build date is most likely a few month earlier (speculating here). It's common problem with that tire when sitting in the lot for a prolonged time. Audi has a TSB for that. I had to have two tires changed by dealer to mitigate the minor vibration issue.

Do you have a preferred site for searching Audi TSBs? I tried an internet search for "Audi TSB database" and got a lot of unhelpful references. Thanks.

Glad it all worked out. and that the dealer is getting you new tires. BUT this thread should be read and thought of a recommendation to all that if you sense something isn't right, be persistent until all avenues are exhausted. Don't simply accept a problem - even a small one as normal and acceptable. There usually is an answer - deep down under the layers. This also shows how helpful this forum is with sharing ideas, thoughts and helpful information.

And here is a thought of my own. Is there any way your dealer can get you different tires than the OEM's - even if there would be an up-charge? IMHO, getting a better set of tires - say Michelin Sport's - is about the best improvement in handling and safety you can do for your car. Do a search here and in the B9 Allroad area.

Thanks for suggestion I am still trying to figure out if the issue is resolved or not. I have read around the forum and noticed that they've had it good for a week, only for it to resurface afterwards. But, so far, so good

When you do feel the seat "vibrates", try to run the car on relative new paved highway road. If you don't feel that any more, then that's the nature of the car/tire + our deteriorating coarse highway surface. I do notice somewhat minor vibration in winter time compare to summer time (Just to be clear I compared under same tire pressure psi).
