Just a thought - in the general absence of anything very helpful from Audi - is there a unit in the glove box with SD card slots for nav maps and music? If so, is there also a slot for a SIM card? There is in my TT, but haven't got my A3 yet. If there is a slot, any installed sim card should over-ride the internal sim, giving a possible work-around (if the internal sim is part of the problem). As suggested above, there will be a module in the car that monitors the mobile signal strength and alerts the driver if it drops below a certain level. I found a description (of the probably identical VW car-net system) that says "If there is no phone signal available then a red light is illuminated next to the red SOS button". No mention of a warning/error message on the dash, but that might have been omitted from the description or the function added later. When the SOS system activates as intended (i.e. in the event of an accident), a [text] message is sent automatically to the Audi Emergency Call Centre, so I guess that a minimum signal strength will have been set to ensure that all the info on GPS position, airbag deployment etc can be sent reliably. However, why the dash 'warning' message wouldn't just say "Low mobile signal strength, emergency SOS currently unavailable" I'm not quite sure. You don't have to search long to find evidence of this 'emergency SOS error' affecting loads of different VW and Audi cars, as well as Seat.Agreed, on the contrary my issue seems to happen more frequently when I'm stuck in traffic in central London.
