Hello everybody
I have a problem, noise (interference) when engine is on, especially if the radio station is weak.
Any help?

Thanks

Welcome to the forum Dimitris!

Radio Frequency Interference (RFI) from various engine functions has always been an issue in vehicles. A number of shielding methodologies have been employed which work well but all it takes is one wear item to break through same. For instance, a spark plug cable whose insulation has become electrically porous with age. Or a loosened ground somewhere (always first check battery).

Given so many electrical connectors in modern vehicles that's also a place for interference if not clean/well seated. Many shops apply dielectric grease once a connector has been disconnected to help with dirt/moisture intrusion and thereby more assured reseating.

The more difficult/distant the radio station tuning the more the interference will be perceived.

btw: It's helpful if you list your model and year so we can better understand the relationship.

Thanks a lot for your immediate answer!
My car is a brand new GLA 200 model 2020.

Thanks again

I would say it is still under factory warranty and a trip back to the dealer is in order.
