Speedo & trip come and go

Post by Super90 »

Hey, all.
My speedo and trip counter come and go, the numbers sort of half disappearing, then coming back. Also, my headlights and the lights of the dash get brighter, then dimmer, then brighter, then dimmer. Newest of all, shortly after start up, the ABS light went on as the radio went off, simultaniously. They then both came back on and everything was fine again, but I had to punch the radio code back in to get it on again.
Could this be the ABS sensor, as I've read, or could it be a faulty CAN BUS?

How old is your battery?

Also, what model and year is the car?
