hello, i just bought an 04 jetta bew pd, 180k miles, with the p0299 code and derate, it looses power almost immediately when accelerating after cycling the key, ive tried almost everything so far, replaced the n75 valve, maf sensor, map/boost sensor, pressure tested for boost leaks, checked for vacuum leaks, checked activation and adjustment of the vane actuator, turbo seems to be producing boost, im at a loss of what else could be the issue, I searched all the p0299 threads, but all I can...
04 jetta bew p0299 derated, help!
