Loud ticking / tapping noise once engine is turned off

This was the video the garage sent me with a little explanation - you’ll be able to hear the noise im referring to - as it’s in the garage it doesn’t seem as loud but when outside it’s a lot more noticeable

The only time I've heard mine ticking the way you describe, is when the DPF is going thru a regen and I've parked up and turned engine off.
The regen causes a huge rise in exhaust temperature and the ticking is it cooling down

Pinking is a ticking sound . When a hot exhaust begins to cool down. If it was the central locking pump , you could replicate that sound without driving or even starting the car.

Would car breakers be an option as well ??

I have had it on occasions on my 212 E350CDI, normally after a long run. I just assumed it was something like the exhaust cooling down, its been there for nearly 9 years. I have just lived with it.

It will be the exhaust cooling down in the cold weather.......... get it checked but I very much doubt they will find anything wrong with the car.

No I mean pinking. To me a ping is the sound a submarine makes looking for u boats. OK .

If you say so.

Update - rather than replacing the whole exhaust, as the rest is fine, the second box along from the rear exhaust where the noise seems to be coming from is going to be cut out and replaced with a stainless steel box and welded back together by a garage which specializes in exhausts... £180. Fingers crossed it works!

Last word guy eh ??? OK it sounds like a ping rather than a pink. Better ?
