Original BMW Near-Engine Catalytic Converter Holder for BMW 2, 3, and 4 Series xDrive (2013–2021)

The Original BMW near-engine catalytic converter holder 18-30-7-633-093 is the exhaust hanger that supports the catalytic converter mounted close to the engine on all-wheel-drive 2013–2021 BMW 2, 3, and 4 Series xDrive models. An exhaust hanger ties the pipes, converter, and mufflers to the underside of the car, which keeps the system aligned and limits its movement. Hangers of this type use rubber or rubberized metal so the mount can flex and absorb vibration from the engine and exhaust. BMW marks this holder AWD, and it weighs 75 g. It has been in production since July 2012 and is made in Germany.

Original BMW Parts carry a 24-month parts warranty.

BMW marks this holder for all-wheel-drive cars. A failing hanger tends to show up as vibration through the floor or seats, or as clunking and rattling when you accelerate or drive over bumps and rough pavement. A loose system can also shift out of alignment and get louder. BMW sells the holder as a single piece.
