BMW E46/E90/E91/E60/E61/E87/E83 X3/E53 X5 M47 M57 Diesel Turbocharger Exhaust Manifold Gasket – Metal Turbo-to-Manifold Seal | Replaces Part No. 11627795266

Restore a proper exhaust seal between the turbocharger and exhaust manifold of your BMW diesel engine with this replacement metal turbocharger gasket. Designed for selected BMW models equipped with M47N, M47N2, and M57N diesel engines, this gasket replaces the corresponding original BMW component identified by part number 11627795266.

The turbocharger exhaust connection plays an important role in the operation of a turbocharged diesel engine. Hot exhaust gases travel from the exhaust manifold into the turbine housing, where their energy drives the turbocharger. A properly sealed connection helps direct exhaust flow through the intended path while preventing gases from escaping at the mounting interface.

Over time, repeated heating and cooling cycles, exhaust temperatures, vibration, and component servicing can affect gasket condition. A damaged or improperly seated gasket may allow exhaust gases to escape around the turbocharger mounting flange, potentially resulting in ticking or hissing noises, visible soot deposits, exhaust odors, or reduced turbine-driving exhaust energy.

This replacement gasket is intended to provide a sealing interface between the corresponding turbocharger and exhaust manifold flanges. Its original-style metal construction is designed for the demanding thermal environment of a diesel exhaust system when matched to the correct engine and turbocharger configuration.

Unlike a universal exhaust gasket, this component is identified by a specific BMW original equipment reference. It is associated with selected BMW 1 Series, 3 Series, 5 Series, 7 Series, X3, and X5 diesel applications using the corresponding turbocharger mounting arrangement.

Whether replacing a damaged gasket, servicing a diesel turbocharger, repairing an exhaust leak, or rebuilding an exhaust manifold assembly, this replacement turbo-to-manifold gasket provides a practical sealing component for compatible BMW diesel engines.

Benefits of Replacing a Damaged Turbocharger Exhaust Gasket

Helps Restore Exhaust Sealing

A defective gasket can allow hot exhaust gases to escape from the connection between the exhaust manifold and turbocharger.

Replacing a damaged gasket with the correct component helps restore the sealing integrity of this joint when the mating surfaces and mounting hardware are serviceable.

Helps Address Exhaust Leak Noise

Leaks near the turbocharger may cause ticking, puffing, or hissing sounds that become more noticeable under engine load.

Replacing a failed gasket may eliminate noises originating from the affected sealing connection.

Reduces Exhaust Gas Leakage Around the Turbocharger

A correctly sealed connection helps prevent exhaust gases from escaping into surrounding engine compartment areas.

This is important because exhaust leakage may expose nearby components to unwanted heat and exhaust contamination.

Supports Proper Turbocharger Operation

The turbocharger depends on exhaust gas flow to drive its turbine.

Maintaining the intended sealing of the turbocharger inlet connection helps preserve the original exhaust flow path.

Recommended During Related Exhaust Repairs

The gasket may need replacement during turbocharger removal, exhaust manifold repairs, or other work that separates the corresponding exhaust flanges.

Reusing a damaged or compressed gasket may compromise the seal after reassembly.

Restore Proper Turbocharger Exhaust Sealing

A properly sealed turbocharger exhaust connection is essential to maintaining the intended flow of exhaust gases through a BMW diesel engine's turbocharging system. When the original sealing gasket deteriorates, exhaust leakage may develop around the mounting flange, resulting in unwanted noise, soot accumulation, and possible changes in turbocharger response.

This replacement metal turbocharger-to-exhaust-manifold gasket is designed for selected BMW M47N, M47N2, and M57N diesel engine applications using original part number 11627795266. When matched to the correct mounting arrangement and installed with properly prepared mating surfaces, it helps restore the sealing function of the original exhaust connection.

Whether maintaining an E46 320d, repairing an E90 318d, servicing an E60 530d, or replacing a turbocharger gasket on an E83 X3 or E53 X5, this component provides a practical replacement for preserving the integrity of the original BMW diesel exhaust system.
