It'll be the exterior temperature sensor. Nice toy, tells you how bloody cold it is and how much of a bitch your car will be to start

Actually, chances are it's a trip computer. If there's two rows of connector pins on the back of it, it is.

If you've got a Bosch engine ECU, you can retro-fit trip computer functionality - see the huge thread in this forum for details.
