ML250 2014 the Daytime running light offside does not work

[Stripedcobra]

Hi I have a ML250 2014 the Daytime running light offside does not work in the daytime but does in the evening sometimes. It seems like a loose connection or module. Can anyone help with a wiring diagram or location of module.

A loose connection wouldn't know if was day or night.

A Star diagnostic will almost certainly pinpoint the problem.
