Oil in the intercooler pipes.
Damaged seals between the compressor and the engine will allow oil to leak into the exhaust system so the turbo has to work harder to increase air pressure. The check engine light monitors all sensors of a car engine including the boost pressure sensor. This will reduce the efficiency and boost delivered by the turbo. Worn parts will be replaced and the turbo bearings and seals will be replaced with new parts.
