Looking for reliable ECU repair in Qatar or professional ECU diagnosis in Doha? The ECU — Engine Control Unit — is your car’s main computer. It controls fuel injection, ignition timing, sensors, and hundreds of other functions. When it develops a fault, dashboard warning lights come on, engine performance drops, and the car may not start at all.
