Thread: D4 3.0 Whining after switch off

Mine's the same. No idea what it is but's always made that noise. Only notice it in the garage.

Lots of other vehicle makes have ultra-sonic injector cleaning after shutdown so I think that's likely to be the case here too.

On my Defender, 4,000 miles, sounds like a jet plane pre and post start up...

Start up = Click, clic, slurp.
Running = Turbo whine and very grumbly engine, more like a snarl!
Stop= Click, clic, slurp.

Had it checked over by SHB, who have 10,000 Defenders on lease, and told is normal for Puma 2.4! Not sweat sounding like a V8, more angry and exhausting.

It's not the centifrugal oil filter spinning down?

Have the same noise on mine. D3 has a similar noise but not as loud or as high pitched.
Very high pitched sounds like a capacitor (like ones in an electronic flash)

It sounds like it knows what it wants to be doing and stops when it wants to but after six months of ownership I never noticed it until the day after I installed my dual battery system.

Any ideas?

thanks

I was told by the Technicians at my dealer that the noise is the EGR valve and it is completely normal.
