XF Sport ticking noise on cool down

I understand this loud ticking noise on cool down is to do with the DPF regeneration, but does the noise mean the car has completed a cycle or that it was interupted?

Many thanks all

I don't think there is a definitive answer.

The high exhaust temps could be residual from a recently completed regen cycle, or indicative of one still in progress.

Do you have any problems? I take no notice at all of mine and it seems to be fine.
I've only had the car a week so can't really comment on problems.

I had the noise today for the first time, so that's why I asked. I'm not going to worry about it too much and just make sure the car gets a good continuous run once a week
Mine almost always does it, I recall the Peugeots which I used to drive in the '70s did it too, especially when the service manager at the garage where I worked had just been out in one! I have assumed the hot smell - which only happens occasionally - is related to DPF regeneration. Anyway, I don't worry about either - unless I'm parking on dry grass!
Don't think that will be a problem just now........
Haven't you heard? There's a drought on!

Only in the "Sunny South" up here in the North West we're overflowing in h2o, thinking of fitting rain masters once the Dunlops have worn out

As for the OP, mine is ticking on cool down on a regular basis. I think nothing of it these days and also, as yet, (to date) not had a DPF warning since owning the vehicle some 7 months now
We've had the rain in the south as well, we only get droughts when it rains something to do with privatisation of water, if they build more infrastructure, they make more money or something
