2013 Leon - 2 Tail Light warnings

[dayloon]

Hi,

I've got a 2013 leon and yesterday 2 warnings appeared on the dash saying both the left and right tail lights need checking. But they're both fine. Is there a sensor or something which can cause these issues ?

Halogen bulbs? If so, there is a cold and warm diagnosis. Simply replace both bulbs. Check the sockets.
