boiling liquid noise when engine turned off

anyone else heard this? 110 hdi. if not its back in on friday because the front bumper keeps popping off so will get there opinion then.

Fluid levels all correct?

[dave_beast]

Eolys fluid for the DPF?

[nicksharp400]

should hope so its only done 700 miles!!! not really sure were its coming from sounds like behind dash but could be under bonnet??? i guess its not a normal noise then. ah well thats what a warranty is for.

DSport has climate control so aircon system normally on. Sometimes I've noticed burbling noises from aircon on some cars when the car is stopped. As well to get it checked out anyhow.

i was told the noise is normal, they seem to think that its the coolant pump running on after you turn the engine off. and that there demo does the same. had a fight to get my bumper sorted though. they said a bumper can only pop off if its been hit. my argument was i havent hit it theres absolutely no damage to the paintwork so how can it be. any way was told that the clamp had been incorrectly fitted that holds the bumper on so was warranty after all.

I get a similar noise to the one your describing I put it down to the air con as my last jap car did the same from the aircon

Yip I have heard this noise too on my 110 HDI after engine turned off. Last night after coming home in my VW that did the same kind of thing to and that was definitely the air con system.

Mine does it if the AC has been on

[Albion]

Mine to after engine switched off HDi E 90.

I think it is the ECU doing its checks after switching off, used to happen in my Leon.

Bigfeet?

I was wondering what it was, the AC thus :bow:

cheers!

Air conditioning can make a clunk when it kicks in just after start up too

[madjeff]

My wifes c3 does this also.

[DS3SaBoy]

My VTI does this too.
But it's hardly noticeable from the outside. After I switch it off it's like short boiling behind the middle part of dashboard, not that loud but it's there. In my case it is not connected with aircon use.

I figured it is doing some sort of check, I hope at least
