Lights flashing and radio cut out?

ZeD4Mr · 11-21-2012, 07:00 PM

I got ABS, Hand brake and Traction control light all flashing at the same time on the dash and the radio volume cuts out. Each incident only last less than a second. Everything then back to normal.

This happens 5 ~ 6 times within a 5 min period. I faintly recall that a month back this happened as well.

Anyone have any similar happening to them or any guesses where I should start looking?

07 with Navi.

TIA,

Original battery?

I'd start there. Check the connections for tightness/corrosion. Bit if it's the original battery that's probably the culprit--have it checked.

WHS! Week batteries doing some crazy stuff on a modern bmw

Got a new OE battery before warranty expired last year. Had the symptoms before the dealer gave me a free one.

I don't think it's the typical battery issue where random lights come on since all lights are brake related. Had that issue before and

I just got new pads 3 months ago. Rotor looks fine and radio cut out? That's what really throws me off..

Did you ever figure this out?

Yes, one of the radiator wire came lose acting as low/weak battery. Once reconnect it properly. No symptoms for the last 11 months.

HTHs,
