Seal the connections that keep your turbocharger boosting with the MAHLE Turbocharger Mounting Gasket Set GS33971. This gasket set is a direct-fit replacement for the 1997-2005 Audi A4, 1997-2005 Audi A4 Quattro, and 1998-2005 Volkswagen Passat, supplying the sealing gaskets used at the turbocharger's mounting joints so pressurized and exhaust gases stay contained along their intended path.
Over time, turbo mounting gaskets can harden and leak, which may show up as a hissing or whistling sound, oil or soot traces around the turbo joints, or a drop in boost. If failed mounting gaskets are the cause, replacing them with this set restores a proper seal at those connections. Always diagnose the source of a leak before replacing parts, and consult the vehicle service information for the correct torque procedure and for any additional fasteners or components that may be required.
