FAQs
Can a BMW ECU be repaired?
Yes, most BMW ECUs can be repaired. At ECU Fix, we successfully restore a wide range of ECUs—including engine control modules, ABS units, gearbox ECUs, and more. Instead of replacing the entire unit, our team diagnoses and fixes the internal faults, saving you time and money. Repairs come with a lifetime warranty and are often completed within 24 hours if the unit is in our catalogue.
Is it worth fixing an ECU?
Absolutely. Repairing an ECU is often much more affordable and faster than buying a new unit, which may also require reprogramming at additional cost. With ECU Fix, you benefit from expert diagnostics, no fix–no fee policy, and a lifetime warranty, making repair the smart and reliable choice.
How do I know if my BMW ECU is bad?
Common symptoms of a faulty BMW ECU include:
- The engine won’t start or cuts out randomly
- Warning lights like the check engine light stay on
- Unusual misfires or poor fuel economy
- The ECU won’t communicate with diagnostic tools
- Transmission or ABS issues with no clear cause
If you’re experiencing these issues, it’s likely your ECU is to blame—and our team can test and confirm it quickly.
How much does it cost to replace an ECU?
Replacing a BMW ECU can cost anywhere from £500 to over £1,500, depending on the model and system. In contrast, our repair services typically start from just £120, and we avoid the need for reprogramming in most cases. Plus, we back all repairs with a lifetime warranty.
