Wh knows anything about the alarm system? - mines decided to go off whenever it feels like it! - one thing I've noticed is that the boot light does not seem to go out when the boot is closed and the alarm 'set'. The light seems to settle into a gentle pulsing rythm - which is nice but also flattened the battery during the week. I guess this may set the alarm off so I disconnected the light and.....the same thing happened again. One thing I have noticed - since we've had the car - is that when the doors are opened after a eriod of around 30 seconds the interior lights flash - again in the pulsing style. I pulled the carpet on the passenger side and checked the connections (for what its worth) to the KOMFORT electronique ( I like the german spelling better) module. When the lights are flashing this seems to click light a relay would. The ESP light also makes a brief appearance every now and then on the dash. We like our A2 but our experience to date (3 years) has been that its like a faberge egg - beautiful but fragile! what with various small issues - ESP, engine management light, temperature sensor and poor starting, stealership servicing, etc. I'm reluctant to take it to our local dealer (Northampton Audi) since all they seem to do is jack into the OBD port and read the script without actually thinking about what they are doing. Phew - marathon session this - any pointers?
