when I started the car up today, the red and green light on the RVM flashed alternately quite fast for about 20secs before stopping. Anyone know why it did that? The car hadn't been started for about a week, not sure if this would have caused it. The lights didn't flash in any subsequent starts during the day. Not sure if it means the batter on the key fob need changing but I checked the fob and the red light on it lit up briefly when I pressed the button.

Anyone have any ideas?
 
I think it is an indication that the fob battery meeds replacing IIRC
 
If the red and green flas at the same time then replace the fob batteries. They take 2 lithium ion batteries, i think CR2025.

cheers, its a new key too. I only got it last year which is a pretty crap life for the batteries.
 
LED's flashing together mean its imobilised, flashinf alternatley means the key batteries are on their way out.
 
Isn't this the sequence to show that the alarm has been activated (set off)?
