OE 357905855B — Ignition Lock Cylinder for Volkswagen

Three checks: the code printed on your old part must read 357905855B; the number must fall inside the build-year range in the Applications table; and the connector, thread or bolt pattern must match the reference photo. Codes cast into the housing are the most reliable source.

Position depends on the platform. On most Volkswagen applications the ignition lock cylinder sits on the engine & fuel system assembly and can be reached from the engine bay or the underbody without removing the dashboard. Torque figures and disassembly order are given in the workshop manual for each model.

Standard minimum order is 10 pieces per part number. Mixed orders that combine 357905855B with other engine & fuel system references are welcome — that is how most clients fill an LCL or FCL container without over-stocking a single line.

A supersession happens when the maker revises a ignition lock cylinder and issues a new tail number. The revision normally changes a small physical detail rather than the fit. Where we know a supersession chain for 357905855B we list the current reference; ask our desk for written confirmation before a large order.

Incoming batches pass a dimensional check, a material look-up against the engine & fuel system specification, and a visual inspection for finish defects. Critical dimensions are measured per carton and the photographs are archived against the order number.

Treat it as a wear item: inspect every 20,000-30,000 km and replace at the first sign of leakage, noise or performance loss. Real service life swings widely with climate, road surface and duty cycle, so mileage on its own is a weak indicator.
