Cylinder 3 pressure too low

[BBJ 2.0]

Crafter 2020 140bhp DAUA engine.

I have the error code P03AE00 Cylinder three pressure too low. White smoke and runs rough until engine warms up then drives fine.

I’ve recorded the fuel injector time deviations on my Autel scanner and got….

Cylinder 4 = 12us
Cylinder 3 = -64us
Cylinder 2 = 19us
Cylinder 1 = 32us

Is such a large minus for cylinder 3 an issue and could this be an injector? Would a faulty injector work fine when the engine is warm? I know this is all suggestion glow plugs but just want to be sure it’s not potentially something else.

Cylinder head pressure sensor 3 bank 1 raw value was 47.8 bar when error cade was raised.

Does any one have any ideas or suggestions of tests I can complete to narrow this down?

Thanks James

Any news on what the fix was? I have the same code but no EML or coil light or limp mode. Did a physical compression test but seem ok. I do notice light blue maybe grey smoke on start up but once warm it's ok. Could it be the valves not sitting or stem seals? Will the turbo have something to do with it?
