BMW 5 Series: Exhaust turbocharger
B58TU exhaust turbocharger
Exhaust turbocharger in the B58TU engine
- Exhaust turbocharger made of steel, for cylinder head-integrated exhaust manifold ZIAK¹
- Exhaust turbocharger made of steel, for non cylinder head-integrated exhaust manifold nZIAK²
ZIAK¹ = cylinder head-integrated exhaust manifold
nZIAK² = non cylinder head-integrated exhaust manifold
Due to the exhaust manifold integrated into the cylinder head, the exhaust manifold and exhaust turbocharger housing are no longer designed as a single component for the B58TU engine. This means that the exhaust turbocharger can be individually replaced. The charging pressure is still controlled by an electrical wastegate valve.
The exhaust manifold and exhaust turbocharger housing on the B58TU engine can be implemented either as one part or separately. Depending on the engine version, the exhaust turbocharger can be replaced individually. The following table shows which variant is used by which engine.
