Hi,
Just wondering if any of you can help identify what's going on,
Just recently i've started to hear a constant strange whistley hum while driving my 2006 2.0tdi.
- It doesn't sound engine or turbo related as putting the clutch in, changing gear or revving the engine has no effect on its pitch.
- It kicks in at about 25mph and increases in pitch the faster the vehicle is physically moving.
- It sounds sometimes there is more than one "note", as I increase speed the pitch increases and sometimes once it gets high enough the pitch suddenly drops and begins to climb again as I speed up, as if it has changed gear or something..(the opposite happens when I slow down)
- It does almost sound like wind vibration on something but I can't tell where from.
- I've read it could be alternator related?
Anyones 2 cents is greatly appreciated!
Darren.
