Hi, how did the lights come on - randomly during a drive, or when starting up?

I have had the ABS/DSC/speedo blank fault around 3 times - always when cruising on motorway after an hour of driving in the wet. I have also had the battery warning light a couple of times on separate occasions. Restarting the car makes it dissappear and it doesn't return.

From what I read a weak battery might be causing this, but not sure due to it occuring after a period of driving....

The link to very wet weather may also suggest a sensor issue, but then again it is a bit random and not frequent, so maybe a temperamental ECU after being warmed up by the engine....?
