So I noticed recently that when I start the engine I hear a double buzz (like a mobile phone vibrating), at first I ignored it thinking it was my mobile as I keep it in the cup holders but then noticed it was happening before I put my phone there. Is this normal? I don't remember hearing that noise when I first owned the car, it's only done 10,000kms. It seems to be coming from under where the cup holders/handbrake is.

Any idea's?

 

sounds like the pumps?
