OEM Specifications Ignition Switch Bracket High-Strength Cast Aluminum Alloy Steering Lock Housing with Direct Bolt-On Installation for VW Audi

This Ignition Switch Bracket (steering lock housing) with OE number 1K0905851B is an essential electronic system spare part compatible with Volkswagen and Audi A1, A3, Q2, Q3 and RS series. It holds the ignition lock cylinder and steering lock mechanism, working with the immobilizer system to control vehicle startup and activate the anti-theft steering lock function when the key is removed.

A faulty bracket often causes common issues: unable to turn the key, failure to start the engine, steering lock stuck, and immobilizer error warnings. Our bracket adopts high-strength cast aluminum alloy structure, with precision internal grooves and mounting points, resisting long-term vibration and temperature changes inside the steering column. It is manufactured strictly following OEM specifications for perfect alignment.

It supports direct bolt-on installation without extra cutting or modification. Replacing this bracket restores normal ignition and anti-theft functions. It is a reliable aftermarket replacement part, widely used for auto repair shops and DIY maintenance for VAG group vehicles.
