Vehicle pulsing whilst idling

[Asquith07]

Morning All,

I purchased a 2019 T6 panel van last week, upgrading from a Caddy.
I have noticed that whilst idling, there is quite a strong pulsating feeling in the cab. Seems to be as the belt cylces? But it is quite aggressive.
Wondering if anyone has any advice as to what could be causing that?

Thank you

Are revs constant or fluctuating?

Revs seem constant? No lights on dash , driving well other than the pulsating

Maybe a regen?

>THIS< kind of sound?

Detailed here:

EGR Valve Self Test Procedure (IDE00242)- P046C?

.... Also maybe try Car Scanner Data recording feature to capture some of that in a file - I haven't personally used that feature so I'm not sure how well that works.... It seems to be really straightforward, it just happens. So if the data is of interest I will happily share.

not quite like that mate no. Maybe it is a regen? It runs absolutely fine & only makes this pulsing every few days.. not making any suspect sounds either. I’ll keep eye on it
Thanks guys!
