This morning i finally got around to changing my car clocks back an hour. It may be entirely co-incidental however after adjusting the radio clock (mine is a 2009MY 's' spec) i noted the time/temp/computer readout on the dash had 'frozen' and will not respond to any attempt to scroll through the computer. When I switched off and removed the key the figures were still dimly legible. Any suggestions? eh tu?

If it doesn't come right next time you start the car try resetting it by disconnecting the battery for a few minutes.

You may have to reset the windows (procedure in the handbook) after re-connecting the battery again.

Thanks, will see how it goes this evening. Any ideas why this happens, curious? eh tu?

The car is controlled by a complex network of modules (i.e. computers of various kinds), sensors, actuators and displays. Both hardware and software can (will!) contain bugs which, under certain circumstances, can cause unexpected and incorrect effects. The trigger can be anything from events happening in a certain sequence, or with particular timing, through to low battery voltage or even external effects such as strong electrmagnetic fields. The result can be incorrect displays, incorrect modes selected, or even a complete crash of parts of the system.

Usually these kinds of problems clear by themselves after a stop/start cycle, but sometimes a hard reset (by disconnecting the battery) is required. Or sometimes some other, unusual action is required - I once had the car start up in M&R mode on the terrain response, and every time I switched it off it turned itself back on after a couple of seconds. Eventially it was pressing the HDC button which cleared it, switching the terrain response back to normal! It's computers - these things just happen! (...says a software engineer!)

Of course you may be unlucky and something mat actually have failed, but it's more likely its just confused itself and a re-start will clear it.

Reminds of the joke about the supposed conversation between Bill Gates and Henry Ford......It does appear even cars now need rebooting. However the display did come on when i started the car but with a series of random vertical dark stripes which very slowly faded over about a 15 mile distance.

Dreading what will go wrong next this week, so far dog to vet and still not sorted, this problem and then tonight my tenant tells me oven not working/heating up, hey ho, hope there is some truth in the saying things come in threes..... eh tu?
