Bulb warning but no bulbs out?

Anyone any idea why my car has just put that symbol up on my car when I don't have a bulb out?

Properly confused at it

Cheers
 
Might be a bulb with a loose filament. I road tested an E89 that was doing that and it was pissing the dealer off mightily as he couldn't find it.
 
Just checked all the rear bulbs and the two outer taillight look like the internals are corroded? Maybe them but with them both looking the same I wonder if it's normal :S
 
Worth cleaning off any corrosion you find as a best practice anyway. That might well be your problem though as it will be messing with the resistance of the circuit.
 
Well it was the inside of the bulb that looked corroded. Change them two bulbs and I still have the light on the dash. Does it need resetting?
 
Have you replaced any bulbs with LED's inc. interior, side lights, etc.?
They draw lower current and unless fitted with a can bus device they will trip bulb out warnings.
 
I fitted canbus led to my sidelights and interior over 6 month ago? So I doubt it will be that.
Everything is working. All the LEDs too.

Agree - doubt it's them then. At least you've eliminated that issue, although if I couldn't find anything else I'd swap them back just to be sure as it seems unlikely to be any sort of poor connection of connector, bulb, etc. as it's not intermittent and your lights are all working.
 
Did a last check around the car to see if I could spot a potential burnt out bulb to discover my passenger side led sidelight was on! But very dim. Took it out to find it had started to burn and the components had started to fall off :lol:

Found it like this. Car turned off, key in hand no lights on

Removed to find it like this and the drivers side wasn't far behind

Back looking like this now until I can find some better quality ones :(

Thanks for the help though. Glad I sorted it in the end
 
Tbh that is fairly typical of my experience with those types of LED. I've even had one burn through and fall apart in the light (PITA to get out). I tend to go for the more enclosed ones now.

Yeah I'm going to do the same this time aswel. Although the enclosed ones have less LEDs fitted to them.
I've lost a resistor off the board somewhere in the light I know that much lol
 
These ones (on the right) are the style I go for now; seem plenty bright enough. I have them as indicators as well

Glad you found it. Guess the canbus correction had failed do if was measuring the reduced current draw and giving the error
