What is OEM number 2K0843603 and which part does it identify?

OEM number 2K0843603 identifies a door lock — specifically, a sliding door lock latch — for the Volkswagen (VW) Caddy range. This part is positioned on the left-hand (near-side) rear sliding door and is used across multiple generations of the VW Caddy as well as the VW Transporter/Caravelle T5 and T6 platform. The sliding door lock latch is also referred to as a sliding door lock catch or sliding door latch mechanism — all three terms describe the same component. Cross-reference numbers for this part include 7H0 843 603 and 7H0 843 603 P. Additional cross-reference numbers observed in parts catalogues include 7E0 843 603 D and 7H0 843 603 P. OEM number 2K0843603 may fit additional vehicle models not listed here — always verify against the OEM number on your existing part or with a vehicle identification number (VIN)-based lookup.

Does OEM number 2K0843603 fit my vehicle?

OEM number 2K0843603 fits the VW Caddy (2K platform, Mk3), covering the years 2004 to 2010 as a primary application. Catalogue data also confirms fitment for the VW Caddy III Box Body/Multi-Purpose Vehicle (MPV) (chassis codes 2KA, 2KH, 2CA, 2CH), VW Caddy III Estate (2KB, 2KJ, 2CB, 2CJ), and the VW Caravelle Mk VI (SGF, SGM, SGN, SHM, SHN). The part has also been confirmed on the Volkswagen Transporter/Caravelle T5, and the position is the left rear of the vehicle.

The critical fitment constraint is side and door position: 2K0843603 is the left-hand (near-side) rear sliding door lock latch. The right-hand sliding door variant carries OEM number 2K0 843 604, and fitment for that number spans the VW Caddy III and Transporter T5/T6 range. Fitment is not engine-specific — the latch is a mechanical body component and the application spans petrol and diesel variants alike across all listed model codes. The input data also associates 2K0843603 with the Fiat Punto Evo (199_) and Peugeot 308 I (4A_, 4C_); these are vehicles of materially different platforms with no verified unifying explanation — verify the printed number on your existing part before ordering for either of those models.

Cross-reference data also associates OEM number 2K0843603 with the VW Vento (1H2) 2.8 VR6 (1992–1998) and VW Transporter Mk V Platform/Chassis (7JD, 7JE, 7JL, 7JY, 7JZ) 2.0 TSI (2012–2015); these are vehicles of materially different specification and generation — verify the printed number on your existing part before ordering.

OEM number 2K0843603 may fit additional vehicle models not listed here. Always verify by checking the OEM number printed on your existing part or by using a VIN-based parts lookup.

When should OEM number 2K0843603 be replaced?

Replacement triggers

• The sliding door fails to latch closed on the first attempt and requires repeated pushing or lifting.
• The door does not release from its latched position when the interior or exterior handle is operated.
• A "door open" warning light remains illuminated on the dashboard with the door physically closed.
• Gradual wear on internal springs and pins causes the latch to no longer snap firmly into place, resulting in a loose or rattling door at speed.
• Accumulated corrosion forms a barrier between moving parts, increasing resistance in the latch housing and causing partial engagement or jamming.
• The central locking system actuates but the sliding door does not follow (lock/unlock cycle does not reach the latch).
• Visible deformation, cracking, or fracture of the latch body or rotary catch when inspected with the door open.

Typical lifespan

A sliding door lock latch of this type can be expected to last 10–15 years or 150,000–250,000 km under normal use. Wear and tear describes gradual degradation of springs, pins, and internal latch components caused by daily use. High-cycle applications — such as those found on commercial Caddy vans in delivery use — will shorten this interval significantly, and operation in environments with road salt, mud, or high humidity accelerates corrosion of the internal metal components.
