Weird electrical problems
I've had an issue since I changed my battery to a varta audi spec.
The indicators and wipers don't work I done a battery scan and it's showing as ok. I tried to code the battery with my carista dongle and its unable to connect to the central module. I've cleaned and drained the water from the plenum chamber I have water in my footwell driver side but since I drained the water it doesn't look like water is getting in car anymore. I looked at the electronic boxes under wiper cowling both of them they are dry. I checked some fuses and they all seem OK. I'm a bit stumped as to what to check next.
It says headlight range defective and my right side xenon won't power up I even changed the bulb so it should work as it powers up sometimes for a second or two then goes out
Also tonight my rear indicators have been flashing even though normal operation doesnt work. I took out a couple of fuses from trunk area to get them off and now i cannot open the boot again as its electronic.
Help me guys I'm tearing my hair out!!

The water came from flooding in the plenum chamber im sure I drained the water from the firewall area which is a common fault I havent had the car long, but I've just changed the battery and things started from tbere

Do you still have the old battery? I suggest putting in the old battery to rule out a battery or battery coding problem.
My other thought is that there may be potentional circuit board corrosion issues due to the water problems that you recently had.
