Volkswagen Caddy Door Lock Mechanism Replacement Parts

The Caddy Mk3 ran from 2004 to 2020, and the Mk4 (current generation) launched in 2021, so a 2016 and a 2021 Caddy are from different generations with different door structures. Parts from within the Mk3 generation are more likely to interchange with each other, but a Mk3 mechanism is very unlikely to fit a Mk4 without modification. Always confirm fitment with the breaker against your exact registration before purchasing.

Both years fall within the Mk3 generation (2004–2020), which received a facelift around 2010–2011, so there is a generation boundary within that range worth flagging to the breaker. Parts from either side of that facelift may look similar but can differ in detail, so you should confirm with the breaker using both registrations rather than assuming they are identical. The side (NS or OS) must also match exactly.

Yes, this is important — the Caddy is sold as both a car-derived estate/MPV and as a panel van, and the van body includes a sliding side load door as well as hinged front doors, whereas the car/MPV versions have only hinged doors. A sliding door mechanism is entirely different from a hinged door mechanism and they will not interchange. When contacting a breaker, specify whether you need a mechanism for a hinged front door or the sliding rear door, and give your full registration so they can confirm the correct part.

Yes, door lock mechanisms are side-specific — the NS (nearside, passenger/left) and OS (offside, driver/right) mechanisms are handed and will not swap between sides. In UK-spec Caddys, the driver's door is on the right (OS) and the passenger's door is on the left (NS). Always confirm which side you need before contacting a breaker, and double-check the part they have listed matches your side.

Trim level alone does not affect which door lock mechanism fits — the mechanism is determined by the generation, the door type (hinged or sliding), and the side (NS or OS), not by whether your Caddy is badged Life, Maxi, Kombi, or another trim. The Maxi variants have a longer wheelbase, and if your Caddy Maxi has a sliding door, the breaker will need to know it is the long-wheelbase version as the sliding door track length can differ. Give the breaker your registration and specify the exact door you need to make sure they pull the right part.

No — the engine fitted to your Caddy (whether petrol or diesel, 1.0 TSI, 1.6 TDI, 2.0 TDI, or any other variant) has no bearing on which door lock mechanism you need. Fitment is determined by the generation, body style, door type, and side (NS or OS). You can safely tell a breaker your engine spec but it will not narrow down the part — your registration, generation, and which door you need are what matter.
