Weird warnings about lights - battery problem?

[djbunker8]

HI all
My 13 plate 330D Touring has started playing up intermittently saying there's a rear brake failure or a dipped headlight not working.
When I get out of the car there are no such problems and the warning disappears.

It's either my mind is playing tricks on me or it needs a new battery...? Any ideas?

Thanks

More than likely new battery needed

They love to throw weird & wonderful errors when battery voltages are low

I fitted the Exide AGM battery from Tayna to my F31 late on last year; took 10mins and a few mins to register it to the car (which you need to do)

This is all the battery you need really: https://www.tayna.co.uk/car-batteries/exide/ek950/

Thanks mate appreciate the recommendation.

Yes I've had random warning lights on two E86s and an E90 when the batteries were on their last legs.

I got an Exide AGM from Tayna for my current E86 for a good price, and because it's an older car it didn't need coding.
