Grey/White smoke - Rav4 2006 2.2 d-cat 176hp

[Dino1805]

 

Hello everyone, I have a Toyota RAV4 D-CAT 176hp, 2006 model. I have a problem I haven't been able to solve, so I'm wondering if anyone has had a similar experience. Lately, gray smoke has been appearing, sometimes at idle on red lights, sometimes while driving. The intensity varies. The highest intensity is when it reaches around 70% operating temperature, then it stops and occurs periodically. Diagnostic showed two errors: P1386 and P1550. Regarding engine fluids, it doesn't consume oil or coolant. Injectors have been checked and are within good parameters. If anyone has an idea of what the problem might be, I would be grateful.
