Re: Front driver side grinding noise.
I have this same issue on my 2012 WK2. going in on Tuesday for service. it comes in at around 20mph, then disappears, then returns at 40mph, and goes away again. maybe it doesn't go away but it is not felt or heard.
I can feel it in the gas pedal, the wheel, and the breaks. pads are good. sound, and feel still there while in N roll. I think it is a wheel front wheel bearing or front drive related.
