Used Mercedes-Benz A-Class Door

These are two different generations — the W168 ran from 1997 to 2004 and the W169 ran from 2004 to 2012, so a 2005 door is a W169 and should be compatible with a 2010 car within that generation, provided the door count and side (NS or OS) match exactly. However, the W169 received a facelift in 2008, and while the basic door shell is the same, trim details and glazing rubbers can differ, so confirm against your registration with the breaker before buying.

Yes, this is critical — front doors on the 3-door and 5-door A-Class are different pressings and are not interchangeable, so always tell the breaker exactly which body style you have. The W169 was offered in both 3-door and 5-door variants, so there are plenty of both in the breakers' yards, but getting this wrong means the door simply will not fit.

Trim level — whether SE, Sport, or AMG Line — does not affect whether the door shell itself fits, as the frame and aperture are the same across the range for a given generation and body style. You may find cosmetic differences such as different factory glass tints or door mouldings depending on spec, but these do not affect fitment and colour can always be resprayed to match.

In UK convention, NS (nearside) is the passenger side, which is the left-hand side of the car as you sit in the driver's seat, and OS (offside) is the driver's side, which is the right. Always quote NS or OS to the breaker alongside your generation and body style to make sure you get the correct door.

The W176 generation ran from 2012 to 2018, with a facelift introduced in 2015, and whether a pre-facelift door crosses that boundary to fit a facelift car is not something that can be guaranteed — the aperture architecture may be shared but panel and trim details can differ. Confirm the exact fit against your registration with the breaker, quoting your body style and NS or OS side.

Engine choice has no bearing on door fitment whatsoever, so do not be put off by a door sourced from a diesel if you have a petrol, or vice versa — the door is the same. Colour is simply a cosmetic matter since doors can be resprayed, so focus on confirming the correct generation, body style (3-door or 5-door), and side (NS or OS) with the breaker.
