Peugeot 508 RxH Hybrid4 Throttle input lag when warm

[impaelas]

I have an odd one.

When the car starts cold it starts and runs fine. After a period of uninterrupted driving, cca 30 minutes the car gas pedal becomes unresponsive, very laggy. I'll press it 4-5x deeper than usual, car won't reply and after several seconds RPMs will go up. It feels like playing a computer game with terrible lag.

There are no codes when scanned with Diagbox after the drive. I have tried running tests through Diagbox for the turbo, egr actuators etc but the application doesn't display results (or I can't seem to find them). Apparently they're supposed to be shown on the screen, as instructed by the software, but it isn't.

Last thing that was done on the car was full clutch assembly replacement (LuK) cca 8.000km ago. Guys wanted to change piloted gearbox robot without any tests run and I refused as it was too expensive. Instead, they've changed the hydraulic oil in the robot and the car ran fine for the last 8k km.

When the clutch was replaced piloted gearbox robot had error codes displayed and car went into limp mode as a result. As said, right now I have no codes whatsoever.

If anyone had a similar experience please let me know.


Sub-question: when running ECU tests in Diagbox where are the results shown? Diagbox says results will be displayed when tests are completed but they aren't (or I can't find them).

Thank you,
Imp.

Update;

while running the diag during replacement of the battery cooler a new error popped up which might be the culprit:

P149C Variable resistance turbocharger

Any suggestions as to how to test this out?

Thank you
