Hi all,
Need you guys/gals advice, looked at other posts but not full covered elsewhere so here goes
For past month had issues with lumpy start and idle on my 2019 2.0 TDI (CXHA) BMT 150 Edition Kombi
History...
Van came out VW garage end of Nov 24 after service, mot and v-belt and tensioner replacement under warranty. All fine till start of second week in Dec 24, when the DPF warning came on dash
Van has only 34k on clock and in all that time, never had DPF warning come on, even though I do a lot of short journeys :/
Checking the VAG DPF App, it showed the DPF was defo needing a clear out (regen)...
So after 10-15 mins down the motorway, all cleared (but only goes down to 33-34% after regen these days)
A week later the rough start/idle started. It seemed to happen when engine was cold, once up to temperature it idled fine. VAG DPF showed DPF fine, and scan with VCDS shows no errors. So thought I would get a diesel treatment to clear things out, so got VW Diesel Additive (G 001 790 M3).
Ran it through full tank of fuel, but unfortunately lumpiness is still there. Found that if I start van, and keep revs at around 2000rpm for 2-3 mins, will clear most of the lumpiness. Revs from idle up around 1800rpm are very lumpy before this and if drive away like this can feel it at gear changes.
Checking coolant, still red and no smell of fuel or oil.
Checking oil, at correct level, slight condensation at filer from short journeys, but no smell of fuel.
Dipping clutch when rough idle doesn't change the roughness.
So thought would try another cleaner about a week ago, Forte Diesel Specialist Injector Cleaner, into another fuel tank of fuel.

Only been a few days and around 100 miles, but doesn't seem much difference, maybe a little quicker for the lumpiness to go away.
To me, with the revving to clear it, it seems to be fuel related, maybe injector? But going by other issues, could it be DPF/EGR related? Or something else?
Trying to get van booking in a VW, as has All In One warranty, so hopefully, it will be something that will covered. But if I can sort it myself before then plus plus.
Thanks for any help.
