Hi everyone,
yesterday I started the engine of my Mercedes C220 W204 (2007) without any problems, I passed few kilometres and when the trip ended I switched off the engine.
I noticed very loud clicking sound in the frontal part of the car on switched off engine, see the youtube video.
The clicking sound gone after 10-15 seconds.
I put the key again and turn on position 1 (no any sound), but on position 2 that annoying appeared sound again (the car is still not started).

Watch the video that I made:

Today I put the key in position 2, and there is no clicking sound, everything is normal.

Passed two months I was hearing this sound shortly and periodically only when I was preparing for starting the engine, but yesterday it was pretty loud and longer.

Is it something that I need to be worried, and do you have any experience with problem similar to this?

Regards,
Aleksandar

It can be relay issue, very similar with this clicking sound found on youtube

I checked both fuse boxes but the clicking sound not coming from the relays, any ideas ?

I found that the noise coming from this segment, see the image. Do someone have similar experience?
