Hello everybody!

I´m new here and hope that someone please can help me.
I have some strange electrical failure while driving and the problem now increasing.

The first times, a click (probably a relay switch on/off) was heard somewhere around the passenger side and at the same time, the headlights quickly flashed off/on. A second later, the light for failure in "adaptive front lighting system" (AFS) began to flash. When the car was restarted, everything was normal.

Now things has gotten worse. The last times it happened it´s start whit the same, but now it´s a really fast clicking (like a relay that switches on and off quickly) for about 2 seconds from the passenger side, then all the lights, stereo, NAV screen, climate panel etc. shut down. Just as if the ignition was turned off, but the engine continues to run. After about 5 seconds everything starts to come back, more or less all lamps illuminate in the instrument panel, a couple of alarms on handbrake failure and so one turn up in the display. The NAV screen comes back but is very sluggish, it takes about 30 seconds from pressing something on the screen until something actually happens. When restarting the car everything is back to normal.

Can someone please help me!
