What is OEM number 7H0843604K and which part does it identify?

OEM number 7H0843604K identifies the sliding door lock, right for the Volkswagen (VW) Transporter T5 and VW Caddy III generations. The part covers the right-hand side rear sliding door and applies across the full production run of the Transporter T5 platform (2003–2015) and the Caddy III (2004–2010), regardless of engine specification. It is also known as a sliding door lock mechanism, right or a side sliding door latch, right. The closely related base number 7H0843604 shares the same application; suffix letter K denotes a production revision. The left-hand equivalent carries OEM number 7H0843603 (Transporter) or 2K0843603 (Caddy) and must be ordered separately. OEM number 7H0843604K may fit additional vehicle models not listed here — always verify against the OEM number on your existing part or with a VIN-based lookup.

Does OEM number 7H0843604K fit my vehicle?

OEM number 7H0843604K fits the VW Transporter T5 Van (chassis codes 7HA, 7HH, 7EA, 7EH), built between 2003 and 2015, and the VW Caddy III Box Body / Multi-Purpose Vehicle (MPV) (chassis codes 2KA, 2KH, 2CA, 2CH), built between 2004 and 2010. Fitment is not restricted by engine code or fuel type; all engine variants across both model lines are covered.

The single governing constraint is door side: 7H0843604K is the right-hand sliding door lock only. The left-hand sliding door lock carries OEM number 7H0843603 (Transporter T5) or 2K0843603 (Caddy III) and must be ordered separately. The Transporter T5 platform also underpins the Caravelle, Multivan, California, and Doubleback (Camper) variants, all of which share the same sliding door lock assembly. Cross-reference data confirms an equivalent Caddy-specific number 2K0843604, which is interchangeable with 7H0843604K on Caddy III applications.

OEM number 7H0843604K 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 7H0843604K be replaced?

Replacement triggers

• Sliding door fails to latch closed and springs back open when pushed.
• Door cannot be opened from the inside or outside despite the central locking operating correctly.
• Central locking motor actuates audibly but the sliding door latch does not engage or release.
• Physical binding, grinding, or stiffness felt when the sliding door reaches the closed position.
• Visible corrosion, cracked housing, or broken plastic pawls identified during inspection of the latch assembly.
• Door rattles or moves perceptibly when the vehicle is in motion, indicating the latch is not holding the striker securely.

Typical lifespan

A sliding door lock mechanism of this type typically lasts 10–15 years or 150,000–250,000 km under normal operating conditions. Lifespan is shortened by frequent use in high-duty-cycle commercial applications, exposure to road salt and moisture ingress, and lack of periodic lubrication of the latch pawls and striker.

Inspection interval

No scheduled replacement interval applies; the component should be replaced on confirmed mechanical failure or when symptoms above are present. Annual lubrication of the latch mechanism and striker with a suitable grease is recommended as preventive maintenance, particularly on vehicles used in wet or corrosive environments.
