{"product_id":"engine-control-unit-clone-reset-immo-off","title":"Engine Control Unit [Clone\/Reset\/Immo-OFF]","description":"The Mercedes-Benz remanufactured control unit, also known as an Engine Control Module (ECM) or Engine Control Unit (ECU), serves as a direct replacement for specific Mercedes-Benz vehicles. This particular unit is a Bosch Engine ECU, with part numbers 0261201278 and cross-references to OEM part numbers like 1131531991 and 0261201616. It is listed as compatible with the CLS 500, G-Klass, and ML 500 models.\n\nThis remanufactured control unit is offered with several variant options to suit different needs. These include a 'Clone' option where data is transferred from the original faulty ECU, a 'Reset (Virgin)' option that returns the ECU to a new, programmable state, and an 'Immo-OFF (Unlocked, Decoded, Free Run)' option that removes immobilizer data for plug-and-play installation without key programming. The product page also mentions a 'Locked ECU' option which requires professional recoding. The condition is explicitly stated as remanufactured\/refurbished, and the seller emphasizes that these ECUs are thoroughly tested for reliability.\n\nInstallation of replacement ECUs, especially for vehicles from 1998 and newer, can be complex due to integrated anti-theft systems. Dealerships often have tools locked by manufacturers preventing the installation of used modules. It is crucial for buyers to verify installation procedures with a qualified technician or locksmith who possesses the necessary tools and knowledge for their specific vehicle application. The seller notes that they are unable to answer installation-related questions. Furthermore, some variants, like the Immo-OFF ECU, may display error messages on the dashboard depending on the vehicle type and model, and are recommended for racing purposes.","brand":"Mercedes-Benz","offers":[{"title":"Default Title","offer_id":52689032839480,"sku":"113-153-10-91-80","price":539.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687380179.jpg?v=1784900848","url":"https:\/\/store.motormia.co\/products\/engine-control-unit-clone-reset-immo-off","provider":"MOTORMIA","version":"1.0","type":"link"}
