Description
OEM reference 2204640018. A genuine used, tested Mercedes-Benz W220 S-Class spiral cable (clock spring/squib) — maintaining continuous electrical contact through the full range of steering wheel movement.
The spiral cable — also referred to as a clock spring, squib, or rotary coupler — consists of a precision coiled ribbon connector inside a moulded plastic carrier, positioned at the steering column and wheel hub interface. The ribbon accommodates the full range of steering wheel rotation without breaking any electrical path, supplying power and signals to the driver airbag pyrotechnic squib, the horn, and every control integrated into the steering wheel (cruise, media, telephone, paddle shifters). Its direct role in the airbag firing circuit makes it safety-critical.
Driver airbag or SRS warning light on the instrument cluster — this is the most urgent symptom, indicating the airbag circuit may be broken; horn failure; all steering wheel-mounted controls becoming inactive; a clicking or crunching noise when turning the steering wheel to full lock; or visible physical damage to the ribbon cable.
This is a safety-critical component. Fitting must be carried out by a qualified technician — the driver airbag squib circuit runs through the clock spring, and any error in installation can render the airbag inoperative. All SRS and airbag fault codes must be cleared with a suitable diagnostic tool after fitting. Always confirm the OEM part number matches your specific vehicle variant before purchasing. Returns accepted within 14 days for unmodified, uninstalled parts.
Returns accepted only for genuine faults — faulty on arrival, not as described, or wrong part supplied — requested within 14 days, with all 3 anti-tamper stickers intact. No returns for change of mind, incorrect installation, coding/programming, or buyer compatibility errors; checking compatibility (OEM number, firmware, vehicle) is the buyer’s responsibility.
