Hello. Strange sound something like: 4 clicks followed by a long low beep, followed by short low beep, coming from the dash display. It seems to happen in colder months, first time it happened was last winter, only 2 or 3 times that year. This year it's happening quite a lot. I've noticed it happens when driving and then slow down below 12 mph exactly, every time. If I quickly speed up to over 12mph the sequence stops immediately without finishing. There is no speed limit warning set, and all fluids are at the right level. I do have a video of this I can link if anyone thinks would help.

Any ideas appreciated. Car is 2009 A4 B8 1.8T.

thanks
