Hello all. I have a 2009 2.0 TD and over last few days I've noticed a noticeable humming/vibration sound coming from the engine (I presume) when the vehicle reaches 40+ mph. Acceleration appears to be ok in lower gears but sluggish in higher gears. Engine oil level appears ok as the dip stick is covered in oil, and the light hasn't come on.
Does anyone have any ideas as what's causing it or had a similar experience? I'm worried the Turbo is packing in and hoping its not that?
Thanks in advance.
