Original BMW Left Front Seat Belt Extender Arm for BMW 328i, 335i, and 335is (2007–2013)

Original BMW 72-11-7-330-781 is the left-side belt extender arm that reaches forward and hands the front seat belt to the driver in the E92 BMW 328i, 335i, and 335is coupe. BMW calls it "Hand, belt extender, left," and it sits at the side of the front seat near the B-pillar, presenting the belt so you do not have to reach back for it. The arm weighs 68 g, is made in Germany, and is sold individually. Production of this number began in April 2012. These arms are commonly found jammed, broken, or no longer working.

Original BMW Parts carry a 24-month parts warranty.

The current number replaced 72-11-9-165-381, and BMW rates it as exchangeable retrospectively, so it fits early E92 cars as well as the facelift models. This is the left-hand arm only. BMW applies this part to both the pre-facelift and facelift E92 with N51, N52N, N54, N55, and N54T engines. A belt guide like this keeps the webbing lying flat across the chest and shoulder instead of rubbing at the neck.
