Mail-in ECU and ECM repair
Ship your ECU, ECM or PCM from anywhere in the United States, or arrange local drop-off in Humble. We test the module first and send the full repair quote after inspection.
ECU repair can involve board-level inspection, communication checks, power and ground review, visible corrosion inspection, driver circuit evaluation, and confirmation that the complaint follows the module instead of the vehicle. Common repair requests include no-start faults, ECU not communicating, water damage, sensor circuit faults, injector driver faults, coil driver faults, throttle circuit faults, and intermittent module behavior.
The initial mail-in checkout is $150. That fee covers intake, ECU testing, communication review, visible board inspection, and repair estimate preparation. If a repair is confirmed, the final invoice is sent by phone or email before work continues. Many ECU repairs are commonly around $400, but the actual price depends on module type, damage, parts, and labor.
When module data and vehicle conditions allow, repair and cloning work is handled with a plug-and-play goal. Some vehicles still require installation steps, relearns, coding, programming, or additional vehicle-side diagnosis after the ECU is reinstalled.
We handle ECU repair requests for domestic, European, Asian, hybrid, diesel, truck, performance, and electric vehicle modules. Customers can send BMW, Mercedes-Benz, Ford, Dodge, Ram, Chrysler, Jeep, Audi, Volkswagen, Toyota, Honda, Chevrolet, GMC, Nissan, Infiniti, Tesla, Lexus, Acura, Hyundai, Kia, Subaru, Mazda, Volvo, Porsche, Land Rover, Jaguar, Mini, Mitsubishi, and other ECUs through the intake process.
Start with the intake form and the $150 diagnostic checkout. After payment, pack the ECU with your confirmation details, ship it to the service address, and wait for inspection. Once the module is reviewed, the shop contacts you with the result, the recommended service path, the full invoice, and the return shipping step.
Include the year, make, model, engine, ECU part number, symptoms, scan codes, previous repairs, and whether the module has been opened, wet, replaced, or programmed before. Clear details help the technician connect the bench test to the vehicle complaint and avoid delays.
ECU repair questions
Often, yes. Repairability depends on the ECU type, the failed circuit, corrosion or water exposure, prior repair attempts, and whether the original data remains usable. Testing determines whether repair, cloning, replacement, or more vehicle-side diagnosis is the appropriate next step.
The mail-in process starts with a $150 diagnostic checkout. Many repairs are commonly around $400, but the final price depends on the module, damage, parts, labor, and whether cloning or programming is required. You receive the final invoice for approval after inspection.
Most diagnostic reviews begin within 1–3 business days after the ECU arrives. Repair time can vary based on the fault, parts availability, previous damage, and any programming or cloning work the module requires.
A repaired original ECU can often return ready for reinstallation, but some vehicles still require relearns, coding, programming, immobilizer matching, or additional vehicle-side diagnosis. The final recommendation explains any known next step.
