Uneven idle 50tdi

[Buxton2901]

Hi guys, so my 2019 50tdi have developed a strange idle, once warm the engines seems to rev up and down slightly.
Rev gauge doesn't move but can feel the car rocking slightly.

Has anyone experienced anything similar on their c8?

Video below which is difficult to hear what I mean



Thanks
Paul

When was it last serviced?

Serviced by lookers just before I bought it 2 months ago almost

I’d take it back to them. Last time I had anything remotely similar, and on a different vehicle the MAF was dirty.

Ain't this just DPF regen? Have you been driving short journeys and interrupting it? If it's DPF then just drive it long enough for the regen to finish and then it should go back to normal.

Hey, so what was the root cause? Did you manage to fix it?
