About this product
When relay performance matters, the OSSCA 04126 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Voltage [V]: Zinc V. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 4B0 955 531 A. Matching these numbers confirms a like-for-like replacement with no loss of function. OSSCA is a recognised supplier of automotive replacement components to independent workshops and dealer networks across Europe. All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops. If fitment or specifications do not match your vehicle, our technical team can help identify the correct alternative — use the vehicle selector or contact us with your VIN for a guaranteed-fit recommendation. Replacing worn components on schedule preserves your vehicle's safety, reliability, and resale value — and aftermarket parts from established brands deliver OEM-equivalent performance at a fraction of the dealer price. Every part is dispatched from our UK warehouse with a 30-day money-back guarantee and free hassle-free returns.
Relay buying guide
Why replace this part?
Relays are electrically-operated switches that control high-current circuits (fuel pump, fan, starter, horn) from a low-current trigger. A failed relay can disable critical systems without visible damage and is often overlooked during diagnostics.
Signs you need a replacement
- Component controlled by the relay fails to operate
- intermittent operation
- clicking from the relay box but no function
- relay runs hot or smells burnt
When to replace
No fixed interval — replace on failure. Always carry spare relays for critical circuits such as the fuel pump relay and fan relay.
