I have a 2.0 d and it started sounding like a tractor back in april. Took it to the dealer and they said it was the valve timing solenoid, I had about a week left on my warranty so they changed it.

It has started again so surely a brand new part should go this quick? Or is there more than one timing solenoid?

Can't find a great deal of info online and can't seem tofind it's location on the valve cover either 🤷‍♂️
