Expert 2.0 running issues, P2566 +

Post by Marc2204 »

Hi all! I have a Peugeot Expert 2.0, AHZ engine on a 14 plate.

Recently it went in to a sort of 'limp' mode and it felt like it wouldn't boost above 3k. Code came up as P2566. I changed the solenoid on the back of the engine, 98 018 876 80 and the code has disappeared, however it still is not running as should, with the same 'lack' of boost above 3k. The solenoid I changed was the one that the turbo actuator connects to, I believe that would be the right one!

I've tested the vacuum lines as far as my knowledge will carry me, and the actuator moves under vacuum, and also on start up and rev.

I've attached some screenshots of a recent live diag, unsure if this sheds much light, but any pointers would be greatly appreciated!!

Maybe some more information before anyone replies.

Moving the actuator by hand with the ignition on, it goes the full range, from 0 to 100%, so I believe the position sensor is reading as it should.

The value of the reading never drops below 60% when driving, even under load up a hill. The actuator is getting -15inmg at idle, and when revving under load it goes to -10inmg, I'll see if I can attach the video - unsure if this adds any value.

The vacuum pump (RHS of engine is making around -25inmg at idle. Few screen shots below for added information. Hoping someone can shed some light.

Cheers
