Alfa Romeo Mito 2009 1.3 JTD DTC P0101

Hello all,

This is actually never ending story, what I already checked/changed:

- New original MAF
- New original EGR
- Cleaning boost sensor
- Checking boost actuator
- Cleaning EGR hoses
- Checking for leaks

and many more...

Fault is intermittent.
There are no visible symptoms of this problem, cars runs smoothly, accelerating properly. Only fault in ECU.
The easiest way of making the fault is to run at 2000 rpm and to release the accelerator. The yellow light will turn on.

Please help!
