I am guessing that you have probably solved the problem by now but I also couldn't find the relevant info on the flashing aircon led light on the forum.
The climate control does a system check when it switches on and if there is a fault it flashes the aircon buttons led. Normally 8 flashes are the outside air temperature sensor is at fault, this is located in the door mirror on RHD cars this is in the passenger mirror and can be seen as a black dimple sticking out of the bottom of the mirror case. If you take the internal finishing corner cover off the door, the multiplug for the mirror is behind, if you unplug the mirror, switch on ignition and check that you still have the same fault code (8 flashes). To test the sensor plug a multimeter on the resistance setting onto the 2 green wires which are at the end of the plug next to the missing pin, resistance should be 20-23 depending on temperature. It is possible to replace just the sensor if you can get one seperate or off a damaged mirror. To do this carefully remove the mirror glass, this is done by tilting the mirror glass and using a small screw driver so that you can get behind the glass and easy the plastic claws that retain the mirror glass onto the mirror adjustment motor housing. The sensor is then visable in the bottom of the mirror, follow the wires back into the sleaving which is clipped to the mirror internal frame and inside are 2 small spade terminals to disconnect. Plug in new one, test resistance on multiplug then reclip glass back in. Should now solve your flashing led light on the A/C climate control panel.
