More details are available from you.
Tell me what you attempted.
So, what's the latest software?

Excuse me, Something is wrong with my MMI display. Except for the Bluetooth, it undergoes regular micro-cuts and functions normally. A clicking noise, resembling a relay, can be heard beneath it, behind the controls for the heater, every time it cycles on and off. That's a 2011 Audi A5 2.0 TFSI Quattro Coupe. Assist me in identifying the error. I appreciate it.

Has trying to upgrade the internal software been something you "provoked" to cause this problem? On the other hand, when did you first notice the issue, like when you installed the new 12V battery in the car?

I haven't attempted to upgrade the internal software, hello. The symptoms didn't start until two days after I inserted a new battery, which was fifteen days ago.

Then you should be sure to check the oecus for any mistakes.
VCDS from Ross-Tech can accomplish this.


Did you plug in a charger when you swapped out the battery?

When I changed my battery, I didn't plug in any plugs. The screen fades off every twenty seconds, and the module just below it (Audi Multimedia) is hidden. Whenever the screen goes dark, it makes a clicking sound.

There is a positive (+) and a negative (-) point under the hood where you can plug in a charger or utilise for a jumpstart.
Your current issue may have originated from changing the batteries without a charger, but I can't say for sure.
remember to look for errors in the oecus.

Hey there. Video CDs will be utilised by me. Three weeks ago, I swapped out the battery. Before, I failed miserably at jumping starts. I haven't used VCDS to recode it yet! For what purposes is "under the hood" used? In the engine compartment, up front, I do have a positive and negative terminal. Now what am I to do with it? I appreciate your assistance.

To attach a jump starter or charger, use the plus (+) and negative (-) connectors located in the engine compartment.
In the boot, you shouldn't connect these straight to the battery.
