Hi all. Looking to do big service over Easter and was hopeful one of you had had knowledge of niggling noise. Tbh it hasn't got any worse since I purchased and is just so strange. The noise is like a chirp squeek sound and happens immediately after stopping engine. In fact engine has stopped and then noise happens for about 5 seconds after. Thought originally drive belt pulley but noise continues after engine motion has finished. I think it might be common because 3 of the cars that I looked at all done it. Any ideas? Would love to sort when I do service.

Mine does exactly this, about 5 seconds and its like a rocking squeaking sound, its got to be a pulley or tensioner maybe even fan slowing down. Its done it 5 years i have had the car.

Mine does this I think it is the turbo actuators or EGR valve or both going through a self check, think they also do it at start up but you can't hear it then over the engine.

I'm sure someone more technical will either confirm this of give us a better explanation 2010 3.6TDV8 Stornoway Grey/ Black interior - gone

1998 4.6HSE Blue/ Cream interior (can't remember exact colours) - gone
1977 White - gone (should have kept)

Mines definitely not any of them, this is a bearing noise from fan or a tensioner.

Mmm. Originally I was thinking it was idle wheel or tensioner but this noise is after shutting down. Do engine is stationary its like something is free spinning for about 5 secs after engine stops. I'll try and get video.

This is exactly what mine does the noise is after the engine stops 2010 3.6TDV8 Stornoway Grey/ Black interior - gone

The only other thing spinning is the fan. Everything else will stop. if it’s the fan spinning it could mean the viscous coupling has gone fubar....

Does it do it when the engine is warm and cold?

It could be the EGR valves cycling back and forth.

If so, It’s normal, nothing to get too worried about.  There is nothing that can't be fixed with a hammer😜😜

Sounds like mine is the fan noise, its like as the fan slows down the noise does around 3 seconds i counted after engine stops. Would a new fan fix this? If so i might get a new fan belt aswell dont think mine has ever been replaced and now on 113,000 on clock.

The high pitched hum and squeak squeak squeak sound is the engine management repeatedly cycling the throttle bodies to clear them of any soot deposits..

Ooooo so this is normal then. No further action.

This sound is entirely normal. It's the EGR valves and throttle bodies doing their reset cycle (They reset each time you turn the engine off and take the key out)

They only squeak because they're old and the original lubricant has worn off.

Hi all,

This noise has been getting on my nerves too, ive taken a video and uploaded to youtube - is this the same noise as experienced above?

Can anything be done about this, its quite embarrassing.

Yes, that's exactly it.

It's normal. 2015 Range Rover Autobiography 4.4 SDV8

Ok, is it even worth trying to oil them? is it even possible?

The throttle bodies are on the front of the intake manifold. To give them a proper clean would involve removing it, which is a pain in the backside, as it usually also involves unplugging various sensors, removing the heatshields and unplugging some of the injectors. Cleaning may only take 30 minutes but removing and re-installing when you haven't done it before can easily take over 3 hours.

You should be able to just emovr the front hoses though and gain some access. You'll have to search the forum to see if anyone has had any success. My throttle bodies on my old 3.6 were clean so, I left them alone. 2015 Range Rover Autobiography 4.4 SDV8
