Hi a couple of weeks ago coming home I got a random 3 beeps but nothing showing wrong today going up hill sustained foot down again I got 3 beeps then nothing then 10 seconds later 3 beeps and something flashed on dash but was so fast couldn't read it and as gain nothing else wrong, I checked all the fluids when I got home except oil, letting engine cool but font see anything wrong, also the sounder behind dash doesn't always work so I'm not sure if this happens often or if I should be worried, apart from sunroof not working and few bulbs out it starts, drives, brakes gine with no overheating or other problems, TIA
