Apart from changing the fluid on the transmission there's not much for the average DIYer can do but get yourself a VCDS cable and software and check for any stored fault codes as that will help with diagnosis.

 

The flashing display means a fault has been stored on the HVAC controller, this could mean anything from low aircon gas pressure to faulty flap motors or supply faults.

So again checking for codes is your first step.

 

The misting up and water leak could be a leaking heater matrix, misting up will be worse if aircon is also not working
