can anyone shed some light on my speedo

[D1 WTF]

here is a youtube of what it does

it sometimes goes funny.  normaly within first 20mins of driving then it sorts it self out a bit

it is suppose to be at a constant speed of 80-90 (obviously on private roads)

Dodgy connection / earting?.. could also be the speed sensor going faulty at the wheel? Not exactly sure, but looks like a nice feature lol

[D1 WTF]

lol cheers, sometimes it seems like it has been connected to the boost gauge.  

will get it checked soon, i dont mind it doing it on the motorway etc, but when it does it along a stretch where there is speed cams and i am being ultra careful, it is a bit worrying.
kind of makes you think that when it isnt playing up, is it actually reading correctly
