Hi All

I have a Volvo S40 2007 and I'm having strange issues with the dash board!

The car runs fine and has no mechanical issues, but when you first unlock the car and get into it and put the key in the ignition and then turn on the engine the dash stays off, (NO POWER) but once I have started the car the interior lights dim down and when completely off the dash comes alive again?

When the car is running and you switch the interior lights on the dash goes off again, When the light is switched off it powers up again, and this also applies to opening the door when the car is running, doors open interior lights come on dash goes off, door closes dash comes on again???

(repost as I have same issue)

Any answers would be greatly appreciated!
