2004 S60 2.4 104k miles:

My message window gets stuck displaying only two windows when i try to scroll through the messages. It will switch between then for about 4-6 times then will go back to displaying all the windows. It doesn't always happen, but more times than not.

Any clue how to update the computer or what might be causing this problem?

Cheers.

 

Check with the Dealer and see if there is any software upgrades for the car.
