I got a letter from my dealer earlier this week. I actually noticed this problem a few weeks ago but forgot about it right away. When taking the car to the dealer I’ll ask for a software update to fix the bug with clock losing time sometimes.
Just had mine modified - was done at the same time as my 3 month (well 4 in my case as i left it late) quality check. I got the impression it was going to be done to all V40's, well in the UK at least. Letters starting to go out.
