2011 S3 hazard light flash

[RPB]

So, I walk up to my car, press key fob once, get in and as I sit down I notice the hazard lights flash only twice I think it was. By the time I notice it they have stopped. I don't see it often, but what the hell does it mean?

They will, if coded, flash twice to unlock & once when locking, but this should of finished by the time you got in the car easily.

Ya know what NHN, thats so simple an answer its probably right! lol.
I may have unlocked it right as I got next to it instead of further back perhaps? Hmmm, worth a teat tomorrow.
