P02A7 fault code, injector advice please.

Hi all,
Been having the above fault code recurring for the last few weeks. I know as a general rule of thumb the highest reading injectors are normally the culprits, I’ll add screenshots of the iid readings and if anyone has any input please let me
Know.

FYI cold start hasn’t been great this winter with extended cranking and it seems less smooth at low rpms than I remember.

Thanks In advance for any help.

Nick

It's the low ones you need to look out for. No 2 is a bit suspect and should "ideally" be around 850 or above. The others may be trying to compensate so it's often worth swapping the suspect injector with a better performing one, and run the live values test again. yµ (idµ - eAµ) ψ=mψ

I have a similar problem on my 05 TDV6. Lots of white smoke but apart from that the engine seems to run reasonably well. I did fit another, used, injector but there wasn't much change. I will be trying another used injector soon. Has anyone had any luck getting these injectors cleaned on a test bench? I have been told that the injectors can't be overhauled.
