Fitment questions
Will a central locking motor from a W220 S-Class fit my W221?
No, the W220 (1998–2005) and W221 (2005–2013) are distinct generations with different door constructions and actuator designs, so the motors are not a straight swap. Confirm the exact part number with the breaker against your registration before buying.
Does the year of my S-Class matter when buying a used central locking motor?
Yes, generation matters most — the S-Class has run across several distinct platforms: W116 (1972–1980), W126 (1980–1991), W140 (1991–1998), W220 (1998–2005), W221 (2005–2013), and W222 (2013–2020), and motors from one generation will not transfer to another. Within a generation there was also a mid-life facelift — for example the W221 was facelifted in 2009 — so confirm with the breaker whether the pre- or post-facelift motor matches your car's build date.
Does the trim level affect which central locking motor I need — for example, does an S350 motor fit an S500 or S63 AMG?
Trim and engine variant do not affect which central locking motor is fitted — the motor is determined by the generation, door position (NS front, OS rear, etc.), and build date, not by whether your car is an S350, S500, or S63 AMG. You may find cosmetic differences around the door card if the donor car had a different specification, but the motor unit itself is interchangeable within the same generation and door position.
Will a central locking motor from a W222 facelift (2017 onwards) fit my earlier W222?
The W222 ran from 2013 to 2020 with a facelift introduced in 2017, and while many mechanical components carried over, whether the central locking motor is identical across that facelift boundary is not something to assume. Check the part number on your existing unit and confirm with the breaker against your registration before purchasing.
Can I use a central locking motor from a Mercedes E-Class or C-Class on my S-Class?
It is possible that some actuator units are shared across Mercedes-Benz platforms within the same era, but this is not something to take for granted — door sizes and module configurations differ between the S-Class, E-Class, and C-Class. Ask the breaker to cross-reference the part number against your specific S-Class registration rather than assuming cross-model compatibility.
Where can I find a used central locking motor for my Mercedes-Benz S-Class in the UK?
Findapart lets you request quotes from UK vehicle dismantlers (breakers) who specialise in Mercedes-Benz stock, so you can compare prices on used units from the correct generation. When you make your request, include your full registration, the door position you need (for example nearside front or offside rear), and ideally the part number from your existing motor to help the breaker supply the right unit.
