Have a 2010 Audi A3 and had to replace battery. Chose an Audi battery (ordered thru vin#) to replace it with. Had some significant work done, involving abs and oil leaks. Shop said they did a hard reset. They did not place code for new battery into the computer, car now has power issues where a/c will cut off in the middle of a drive, or radio stops working with no controls working properly. What is the solution to power management? Is it as simple as coding the new battery into the computer?
