The cost of replacing a car’s computer can vary depending on a few factors, such as vehicle make, age, and what features the car has. When many to the “car’s computer”, it can often mean the ECU (Electronic Control Unit), also known as an ECM (Electronic Control Module).
On average, the cost to replace an ECU can range from $500 to $3,000 or more. Labor costs for installation and programming can add another $150 to $500.
Other factors include whether or not you want an OEM (Original Equipment Manufacturer) part, or you’d like to seek out a refurbished OEM.
With that said, ECUs can often be repaired or reprogrammed, though, which can mitigate the cost and prevent you from having to buy a whole new unit. You can find out how to diagnose and repair, or replace your ECU from The ECU Pro.
