Focus Mk2 1.6tdci air cooler diagnostics

Post by yagr » Sat May 23, 2020 6:40 pm

Hi,
I noticed large temperature jumps in the intake manifold. The temperature measured by IAT can rise from 20 degrees to 50 in a few seconds. It cuts off the fuel dose. I suspect the intercooler is not permeable. But it's more about crumpled lamellas and the lack of flowing cooling air. How to quickly diagnose it with forscan? What PID to look at? Or is it not an intercooler that only causes the EGR to work incorrectly?
Thanks in advance for the hints.
