Code P0299 pulled after check engine light lit

This is a code for turbo boost under pressure, it will not hurt the engine so much that it is just not going to develop the power as intended and it will be very sluggish. Problem will be with the turbo control for the waste gate, it may be leaking boost back into the exhaust, get this looked at first.

There are two types of wastegate, most common of which is the internal wastegate. This is usually found on cars with low boost settings like 5 psi or 6 psi, or even up to 10 psi. An internal wastegate is found inside the turbo housing and is a crucial component of the turbo itself. The diaphragm is connected to a hose that goes to the turbocharger compressor outlet, charge pipes or intake manifold. The gate is opened when the diaphragm on the wastegate is actuated. When boost pressure exceeds a predetermined amount, the diaphragm opens the spring-loaded wastegate bypass flap, allowing some of the pressure to go around the turbo's impeller, slowing it down. The excess pressure is then evacuated to the exhaust
