Turbo is not making enough boost
A turbo is a small air pump driven by the exhaust that forces extra air into the engine. Boost, the extra air pressure, is lower than the computer wants.

Look at the air hoses between the air filter, the turbo and the engine for loose clamps, splits or oil spray.
What to watch for
- Weak acceleration, mostly on hills
