Nicky -

I noticed today that I have a similar "blinking" problem with D5 and N. It is slight, but visible. Today, I had the air at max plus the radio on. When I turned on the blinker to turn left, the D5 light blinked in time with the blinker. It was slight, but there.

I think I am going to have my battery tested.

 

My battery was replaced in May....so I don't think thats what it was....mine doesn't do it that much....just when all of the accessories are on....
