Hi all

I drive a 2016 octavia vrs and the passenger side daytime running light has dimmed but the drivers side is bright. Can you rectify it easily yourself ???

Worth first checking electrical connections and making sure that all the earth connections are good and there is no corrosion in any of the electrical connectors.  Assume its an LED DRL you are running??  The LEDs do dim when you are turning, just in case you had an indicator on or something like that.

@wyckaie it could be a failing module on the headlight  I had the same issue on My MkIII.
