OVERVIEW
Genuine collared bolt for the original horn bracket
The N-019-538-9 Genuine VW/Audi bolt secures the assigned horn mounting bracket on the configurations listed below. Its collared hex head provides the specified bearing surface at the original attachment.
The signal horns and alarm horn use different brackets and fasteners depending on equipment. This listing covers the particular M8×18 bolt assigned to the stated connection. It does not include a horn, bracket, relay or wiring.
Technical details
- Complete factory number: N-019-538-9.
- Factory specification: M8 × 18.
- Design: hexagon-head bolt with integral collar.
- Quantity supplied: one individual bolt.
The collar and specified length are part of the attachment design. A plain hex bolt of similar diameter may not provide the same bearing geometry or thread engagement. Match the complete original number and mounting position.
Common reasons to replace
- The original mounting bolt is missing after horn or front-end service.
- Threads are damaged or no longer engage correctly.
- The hex head is rounded or damaged.
- Corrosion has damaged the fastener.
- Incorrect replacement hardware was previously fitted.
Inspect the bracket, body mounting point and mating threads. A new bolt cannot repair a cracked horn bracket or diagnose a silent horn. Check the horn, wiring, fuse and controls separately when investigating an electrical fault.
Vehicle fitment
Confirm the original horn bracket and bolt position. The Eos alarm-horn application specifically requires PR 7AG equipment; signal horn and alarm horn hardware must not be interchanged without verification.
