About this product
When relay start repeater performance matters, the BOSCH 1 986 SE3 851 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Manufacturer Restriction: BOSCH, for article number: 0001231002, for article number: 0001231016, for article number: 0001231032, for article number: 0001231046. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. This part supersedes original equipment references: 0001231002, 0001231016, 0001231032, 0001231046 and 13 more. Matching these numbers confirms a like-for-like replacement with no loss of function. BOSCH 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 with tracked delivery and a 14-day money-back guarantee with hassle-free returns.
