Hi guys, 2.0 TDI BRE. I’ve got an issue with lumpy idling and white smoke when the engine is cold. The issue goes away once the engine is warm. I’ve looked at the injector correction vales and it’s seems to me cylinder 4 could be a potential issue. The worst value when cold on injector 4 was 1.58mg/H, dropping down to 0.3mg/H when warm (see pics). Maximum torsion value is -1.47*KW so I think the timing is fine. COLD: WARM: TORSION: EXHAUST WHEN COLD: What might cause an injector to start at such a high correction quantity, only for it to drop to a normal value when warm? Any help or insight would be much appreciated!
