I need your help as I worrie like never before. I’m owning facelift 1.6diesel sport from 2015. Everything is fine so far except one thing. From one week now I can hear a weird noise comming from passenger side if dash board. It appears every 10 sec for 5 secs. Simillar feeling when AC comes on but when I hear it is off. I opened the hood while engine runs and sonething goes on with the same frequency from left hand side around alternator. Would you have any suggestions? Will appraciate it.
