OVERVIEW
Restore the original pillar trim fastening point
8E0-853-379 is the Genuine VW/Audi threaded bushing used in the specified exterior pillar trim attachment. It provides the receiving feature that allows the matching trim fastener to secure the molding in its intended position.
A damaged receiving bushing can allow the fastener to turn without holding the trim properly. Restoring the original insert helps the molding seat correctly against its supporting structure without forcing the screw into damaged material.
Technical details
- Complete factory number: 8E0-853-379.
- Factory specification: Factory threaded trim bushing, part 8E0-853-379.
- Design: molded receiving bushing for the assigned pillar molding attachment.
- Quantity supplied: one individual factory bushing component.
Match the receiving shape and complete part number to the original attachment. Similar-looking plastic inserts can have different retaining features and screw requirements.
Common reasons to replace
- The receiving thread is stripped and the screw no longer tightens.
- The molded retaining feature is cracked or broken.
- The original bushing was lost during molding removal.
- The molding remains loose after the fastener and trim have been inspected.
Check the trim, screw and supporting opening together. A cracked molding or damaged mounting aperture requires its own repair; tightening the screw harder can worsen the damage.
