2016 V60 D4 Strange engine dips in power/revs when cold

I'm having a strange issue with my 2016 v60 D4.

Sometimes when I start the engine after it's been off overnight, I'm getting some power dips in the revs. It's almost as if the start/stop is engaging but then decides not to at the very last minute and the engine keeps running.

I also feel it when I'm driving around 10-20mph, and it feels as though there is a slight loss of power that then comes back again, so the drive feels a little jerky/hesitant.

Car drives absolutely fine when warmed up.

Any ideas what it could be?

Basically same symptoms as my XC60 D4, mine had a spilt in the inlet pipe, which can't have been helping, but ultimate issue was EGR valve. FYI, local independent quoted £210+vat for labour, Valve about £550+vat and cooler about £480+vat.

I really hope it’s not the EGR as I had a new valve and cooler fitted 7k miles ago!

Ok, could be an air leak or a dodgy sensor then. Has the EMAP pipe been checked? These can become clogged and cause similar symptoms. There's a couple of other sensors that seem to need cleaning after a while once EGR has been replaced too, these are talked about on the big EGR discussion thread on this forum.
