Likely water damage to the central comfort control module, which is (stupidly) located under the carpet. Run a VCDS (RossTech) scan to verify this.

Run a VCDS (VAG-COM, from RossTech) scan to see what the temperature sensors are reporting. You may need a new coolant temperature sensor. Also, if the water sensor at the bottom of your coolant recovery tank is defective or disconnected, you will get a flashing light that might look like a high temperature warning to some.

On this website you find fuse box diagram and description for Audi 80

Alright it gets complicated...
I'm assuming you have a 4L (2005-2015) model.
It will be in the under bonnet (hood) relay panel.

It can be any two of five relays depending on engine and year!
For petrol engine models up to June 2009 it's relays A1 and A2.
For petrol engine models from June 2009 it's relays A5 and A6.
For diesel engine models (3.0 and 4.2) it's relays A5 and A6.
For diesel engine models (6.0 V12) it's relays A2 and A4.

For all fuse and relay information (RHD & LHD) see here:
