More software glitches!

[Swaineman]

My car is now 1 year old and I have had all the usual software issues that have befallen other members on here, speed reconciliation function failure which was fixed to be followed by the star keys failure which has also been fixed after about 6 Months of backward and forwards to the dealer. Originally on r46 edition now on r61. However after about 3 weeks a new issue has raised its head, the speed recognition function has now decided not to recognise only derestricted signs?
Anyone else had this, back to the dealer again!
