Horn not working? How to tell if it is the clock spring
On Volkswagen, Audi, SEAT and Škoda cars the horn button connects through the clock spring (squib) behind the steering wheel. If your horn has stopped and your steering-wheel buttons have gone dead too, or the airbag light is on, the squib is almost always the cause. If only the horn has failed, start with the simple checks below.
Is it the squib?
Horn and steering-wheel buttons have both stopped working
Almost always the squib (clock spring). Both run through the same ribbon behind the wheel.
Airbag warning light on, with or without a dead horn or buttons
Usually the squib on these cars. A scan of the airbag module confirms it (see below).
Cruise control unavailable and the steering-wheel buttons are dead
Very likely the squib. The cruise switches are on the wheel and lose their connection with it.
Only the horn is dead; buttons work and there is no airbag light
Check the horn fuse, relay, wiring and the horn itself first. The squib is possible but less likely.
What a scan typically shows
- 00588 Airbag Igniter; Driver Side (N95): Resistance too HighOlder-style fault display, e.g. VCDS on earlier cars.
- B1000 1B Driver airbag igniter: resistance too highNewer-style display; often shown as B10001B.
- 01326 Control Module for Multi-Function Steering Wheel (J453): No Signal/CommunicationLost communication with the steering-wheel buttons module. Older-style display.
- 00466 Control Module for Steering Column Electronics (J527): No Signal/CommunicationLost communication with the steering column module. Older-style display.
- U0212 Lost Communication With Steering Column Control ModuleGeneric OBD-II code, as shown by many standard code readers.
- Many basic OBD-II code readers cannot read the airbag module, so "no codes found" does not rule out the squib.
- If a fault reads "short to positive" or "short to ground", do not clear it. Have the system checked first.
Why a failed squib causes this
The squib is a coiled ribbon cable that keeps the horn, airbag and steering-wheel buttons connected while the wheel turns. Years of steering wear the ribbon until a track breaks. The horn circuit is one of those tracks, so the horn stops working, often together with the buttons and the airbag light.
We repair the two VW Group squibs behind most of these faults: 5K0 953 569 repair and 5Q0 953 569 repair.
Other causes to rule out
- Blown horn fuse (check the fuse box cover or owner’s manual for the horn fuse)
- Failed horn relay
- Faulty horn unit, often from water or corrosion behind the bumper
- Broken wire or corroded connector at the horn
The squib sits behind the driver airbag. If you remove it yourself, follow the manufacturer’s airbag safety procedure. If in doubt, drive in and we’ll do it for you.
How we repair it
Strip and inspect
We pinpoint the squib fault and confirm the root cause before any work begins.
Rebuild with OEM parts
Worn or snapped ribbon cables are replaced with OEM items using OEM repair methods — we never solder, as that only leads to short-lifespan fixes.
Test and verify
We test every squib for continuity and function before we send it back, backed by a 12-month workmanship warranty.

Horn not working: FAQs
Why has my horn stopped working but everything else works?+
If the steering-wheel buttons work and there is no airbag light, the fault is more likely the horn fuse, relay, wiring or the horn itself. Check those first. The squib is still possible, but less likely.
Why have my horn and steering-wheel buttons stopped working at the same time?+
Both run through the clock spring (squib) behind the steering wheel. When its ribbon cable breaks, they fail together, and the airbag light usually comes on too. On VW Group cars this is almost always the squib.
Can the clock spring be repaired, or does it need replacing?+
It can be repaired. We rebuild your original 5K0 953 569 or 5Q0 953 569 with a new OEM ribbon, never soldered, and bench-test it. Because your original unit goes back in, no coding is needed. Every repair has a 12-month workmanship warranty.
Is it safe to drive with the horn not working?+
A working horn is a legal requirement in the UK and part of the MOT. If the airbag light is also on, the driver airbag may not deploy in a crash. Get it fixed as soon as you can.
Squib failed? We'll fix it.
Post it in for same-day dispatch and next-day return, drive in near Heathrow, or we'll come to you.
