I have an indefinable sound again and again sporadically….Until now it could not locate or hear the workshop at all because it only occurs once in a while. It always occurs when giving gas in lower thresher range when it occurs…..I once recorded it with the mobile phone…It’s a ratter like if somewhere a relay hangs…….I hang the file here. I got my carens at the beginning of February…very new……..The problem was there from the beginning…….Who can? help me or also has this sound… Thank you and greetings Robert
