T6.1 rough idling on startup

[Eco6.1]

Hi I have a Jan 2020 T6.1 2.0tdi 110 just turning 40k Km, it’s been to the dealer twice for spluttering and shaking/shuddering when started from cold or even after 3-4 hours, it’s started at about 36k and has gotten progressively worse, on two occasions the dealer had added fuel additive, made no difference and has tested the injectors said they were all ok. Any ideas where to go next or what the issue could be, thanks Shay

can you get a video clip of it doing it . . . from the engine bay?

If they accept it isn’t right, and have tried to fix it, then I would point out that you have 2 years warranty left, and leave it with them until it is sorted (with an appropriate loan vehicle).
It’s up to VW to sort it surely ?
