Hi only way to find out what it is would be to scan the car for faults, amber warning is not critical but needs to be addressed.

Why did the battery go flat? How old is it? Has the alternator been tested?

I ask because a defective battery can not be restored simply by charging it.

As cliff says the battery could be the cause of the electrical issues. As failing batteries throw up electrical gremlins.

How old is the battery in your Audi A4? Was it working perfectly fine until this moment? Do you know why it went flat (e.g. car sat for a long time or you left an accessory on such as a light)? Also, is it a standard lead acid battery or an AGM type?
