I've got a 2004 2.0TDI (BKD Engine) which runs fine when the engine is cold, but develops a very rough idle when the engine has warmed up to around 90. I don't think it's the DMF as the roughness doesn't change as the clutch is pressed in.
I've just changed all filters and oil, which had no effect.
Car isn't throwing any codes, and a recent VCDS diagnostic shows that some of my injectors are working harder than others (according to a mechanic).
Bad Injectors? Bad temp sensor?
Any ideas what it could be?
