Is your hazard light or door lock switch acting up on your BMW E46? This is a direct replacement part (OE number: 61318368920) that should fix the issue. It's made from durable ABS plastic and is brand new. Fits a bunch of E46 3 Series models from around 1999-2006, including the 323i, 325i, 328i, 330i, M3, and even the Z4 from 2004-2008. It's basically the little red triangle button on your dashboard. Installing it is usually straightforward if you're handy – you'll need to pop off the trim around your radio/climate control to access it. Make sure to disconnect your battery first for safety. This is an aftermarket part designed to meet OEM specs. If you're not 100% sure it fits your specific model, double-check your old part's number or consult a mechanic. A lot cheaper than going to the dealer! Comes with a single switch.
