Drove the CQ to work and back today. I thought this problem with the diff light was random! But today i have discovered that the light only comes on and off when i engage the car in fifth gear. I even switched the engine off, and it still came on when i engaged fifth!
So the question now is, why? Has any one else come across this problem? The car feels fine so i'm hoping it's nothing major?
Hope you guys can help.
