Mercedes-Benz Steering Wheel Button Switch – W166 X166 GL/GLE Class, A1669051800

This is a steering wheel button/emblem for a Mercedes-Benz, specifically fitting the W166, 172, and GL classes like the GL550, GL350, and G500.

It's a new old stock item – it's never been used, so no wear and tear, but it might not be in its original sealed packaging.

The part numbers are A1669051800 and A1669051900.

It's made of chrome and black plastic.

If your current steering wheel button is looking scratched up or the chrome is peeling, this is a simple and cheap fix to make your interior look fresh again.

It's easy to swap out.

Double-check your model to make sure it's the one you need, but it's a common replacement for these Benzes.
