Recently whilst starting the engine from cold, the dials on the dashboard have started to flicker for approximately 2 - 3 seconds, then stop flickering and read as they should normally. They only flicker once the engine has started and do not flicker before this when the ignition is turned on.
It's a mk1 2005 1.8L focus, petrol, 89,000 miles on the clock.
Any ideas? Is it just a coincidence that has started to happen now that the outside air temperatures are hovering around or below freezing?
If needs be I can record a video of what happens and upload it to youtube to give people a better idea of what's going on.
Any suggestions on what's going on and if this is normal would be appreciated! Thanks!
