Today the Esp fault message came on my car - which it never has before since I've owed it this last 3 years. Tried to reset and it didn't work. When I started my car and had this issue I thought - turn off car and hopefully it will reset. Well couldn't turn off the car! Removed key and car kept running! Finally after reinserting key several times it finally turned off.

Call Audi dealer and set up appointment to get this checked out and felt ok about driving my car home.

So started driving and Esp (car with squiggly tire tract symbol) went out.

Still have issue that the ignition or whatever it is still makes a buzzing sound when I use the key to unlock car door.

Still has been a crazy day!
Has anyone else had an issue with ignition and key, Esp fault message and buzzing sound?

Thanks
