E is displayed as a fault with the system. E on start up whilst the engine is cranking may be low battery voltage, the car sets the air con automatically when starting to air distribution floor, air mixing warmest, air recirculation port outside, compressor engaged. E displayed then after a short time the outside temp been displayed sounds like a sticking air flap motor code 55, 65 or 75. My display has only two digits, AA listed as self diagnostic finished error code 14 is tt1 sensor. A white coloured mixed air temperature sensor in the upper part of the air distribution housing. Values for the sensor are 42.326 ohm at -5 deg C, 32,650 at 0deg C, 19.899 at 10 deg C, 12.492 at 20 deg C and 8.057 at 30 deg C. It may only be a dash top off to gain access to fix. If the outside temp sensor has failed (the little pip under the drivers side mirror) try one from an Alfa 166, the whole mirror pod thing looks the same, mirror glass, plastic cover and plug in connectors, motors etc. I will get part numbers if you want. Hope this helps Andrew
