Front lights problem on one side

[Helmuth]

Hey guys, long time no speech.

So you see she was working perfect but now she seems to want more attention.

About 2 weeks ago: "check headlight" came up and the left headlight low beam did not work any more. Nothing special. I planned to fix that the coming weekend. One day before the weekend: "check fog light" - and the left foglight stopped to work. I thought - no problem, better to fix 2 things in one shot. So I bought the lamps, changed them - all worked.

One week later the same 2 messages were coming up, the same 2 bulbs were failing, one time the first, second time the second. Sometimes the problem goes away after I drive through a pothole, sometimes after some minutes without anything, sometimes it stays.

Since all that is on the left side only - is there a special place/plug to look at? Would be great if one of you had an idea about how to fix that.

Thank you in advance,

Helmuth
