    Hello LZ people.
    This is a Defender 90 Puma 2.4 at switch off with the fan cowling removed. I thought the chuka chuka chuck noises were from the fan but as you can see from the video you still here one chukka sound after the fan has stopped.
    Is this maybe the EGR valve cleaning? It happens almost every switch off but not always.
    8 second video at the link below.

    Would be grateful for any comments on this what the sound is from and how worried should I be.

    Sounds like the variable turbo blade mechanism jiggling up and down. Normal on the Puma. If you watch the motor and rod which is on the right side of the turbo you will see it jiggle it when the engine is switched off.

    Thank you Wimblowdriver for your comment and the attachments. I will take a read through. Looks like the last two attachments are the same. Was there meant to be a different third attachment?
    Much appreciated.

    The motor rod appears to drop when the engine starts and rise smoothly when the engine stops, I can jiggle the rod by hand -there is movement there but at switch off the movement appears smooth.
    Also noticed when watching the rod on this side of the engine, really the noise appears to be coming from the other side. Not having another vehicle the same next to me it is difficult for me to know if this is normal so have recorded the movement below.

    My turbo vane control rod is a bit more enthusiastic than yours at engine switch off (hence my suggested cause of your noise). I have attached the manual page for the EGR valve, which also does a few open and closes at engine switch-off. HTH.
