{"product_id":"engine-control-unit-ecu-2","title":"Engine Control Unit (ECU)","description":"The Mercedes-Benz A1131533479 is a genuine Bosch engine control unit (ECU) responsible for orchestrating powertrain functions, such as fuel injection, ignition timing, and boost pressure. It is a common replacement for failing units exhibiting symptoms like the P2073 suction fan motor fault or issues where the cooling fan engages at high speed upon ignition.\n\nThis unit is available in several configurations, including locked, unlocked, or programmed variants. Depending on the chosen variant, installation may require professional services. For example, some units require programming with specialized diagnostic equipment, while \"IMMO OFF\" Plug \u0026amp; Play versions disable the immobilizer function entirely. Other variants may support auto-programming once installed.\n\nCompatibility must be verified by matching the part number to your original module. If you opt for a cloning service, your original unit must retain communication with the car or a diagnostic tool to allow for secure data transfer. Professional installation or the use of specialized diagnostic tools is often required to ensure the module is properly calibrated to your specific vehicle's electronic system.","brand":"Mercedes-Benz","offers":[{"title":"Default Title","offer_id":52689058562360,"sku":"A1131533479","price":325.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687380392.webp?v=1784901001","url":"https:\/\/store.motormia.co\/products\/engine-control-unit-ecu-2","provider":"MOTORMIA","version":"1.0","type":"link"}
