Hi I am new to the forum. Yesterday I noticed a problem with my 1.33 petrol 2012 Toyota Auris when i turned off the ignition. The dashboard lights starting flickering. Sometimes the check engine warning came on and sometimes the check airbag warning came on. Once you start the car and drive off, the problem stops but once the ignition is turned off the problem happens again. I can't find any signs of water ingress or moisture that it would indicate a water related problem.
