Detailed Description

Standard Ignition PWS284 is built for vehicles that use an electronic brake pad wear monitoring system. This front brake pad wear sensor is positioned at the brake caliper and uses an oval female connector with a 25-inch harness to match the routing needs of the original setup. For BMW i3 owners, PWS284 provides the correct fitment for 2014-2016 BMW i3, front service applications. This part cross-references BMW 34356799329 and WS484 for the same application.

What It Helps Address
