power loss fault code
Hello everyone,
Hello, for some time now I've been experiencing a loss of engine power. The engine goes into safety mode at 3000 rpm. I turn off the ignition and the power is restored.
Once I request more power, it goes into safety mode.
Often on hills or on the highway, the warning light turns orange and sometimes disappears.
I have fault codes P00AF, P0299 on my GLK 220 Cdi.
Previously, I had code P2463. We performed a forced regeneration of the particle filter because it was clogged. It is no longer clogged, the values are correct. We removed the EGR valve; it was just a little dirty. I cleaned and reassembled it.
I replaced the original air pressure sensor A 006 153 97 28 0261230190 with a Bosch sensor, which is now part number 0261230189.
And replaced the intake manifold pressure sensor A0071530028 0261 230 196 with a Bosch sensor part number 0261 230 196.
The turbo fins have no play, and the wastegate seems to be working properly when I inject air.
It's painful to drive in these conditions. Could someone please help?
Sincerely,

Here are the details:
P00AF - Boost Pressure Control A Status
- Stuck Open
- Intermittent
P0299 - Relative Boost Pressure Exceeds Upper Limit
- No Symptoms
- Intermittent
P2463 - Particulate Filter Soot Load, Implausible
- Component Failure
- Permanent
Code P2463 is resolved by performing a regeneration

A number of members, my self included, have had P0299 caused by a failed hose between the intercooler outlet and the mass air flow sensor on GLK250. I don't know if your problem could be the same or not.
