Thanks for the reply Adbro, I have since had more symptoms, but found the problem. For anyone who has the following issues with their a3, dashboard and clocks lights like a disco, clocks going off all together, handbrake light either on when it should not be or flickering on and off randomly, accompanied by, doors locking and unlocking, loss of, indicators, wipers, main beam switching, electric mirrors and the heat controls lighting going bright, and aircon occasionally turning on or off itself (a lot i know), get your car plugged in to a fault reader. If it shows 00470 comfort control wire...etc, or something similar you need to check the following.
Water/washer fluid in your boot or spare wheel well, if not, still remove the inner o/s side panel in the boot and look for signs of moister or washer fluid around the comfort control module that is bolted into the rear quarter of your car, just behind the rear wheel inner arch.
In my case what has happened is above the rear wheel behind the lower part of the head cloth, the rear washer pipe has a connector which has split. Everytime it is used it sprayed fluid all over which in turn ran down onto the module and its multi plugs. I was really luck as all that was needed was to clean the multi plug conectors with switch leaner after drying the area out obviously.
I hope this may help out others with similar or same problems. I have notifications set so will reply to anyone who may have any questions. One happy A3 owner again. :)
