hello good fellows,
it has been a week now and my car is acting up to me and I can't seem to find the source of the problem.
after a long day on the road, about 200 km done, when returning home, limp mode...
OBD scaner is allways on so I picked up my phone and scanned the codes:
P0299 and P2359
both point to low boost pressure in turbo circuit...
already checked:
hoses to an from intercooler, geometry vanes at turbo (free and running), replaced intake pressure sensor, looked for oil spots at intercooler that may indicate a puncture...
the egr circuit is not to significative since it is blanked off (unplugged) with egr delete mod plugged in... however I checked it again and it continues clean inside...
I begin to believe that actuator is causing some kind of trouble, although I check its movement at start, idle and acceleration, and it is moving full range...
DPF is out of the question, I don't have one... mine is Catalytic (so no DPF sensor or exhaust back pressure sensor)
can anyone shed some light on my quest?
thak you all in advance...
