Frequently Asked Questions

1. How much does it cost to repair a ECU?

At ECU Fix LTD, engine ECU repairs typically start at £250, depending on the vehicle and type of fault. This includes full diagnostic testing, professional repair by skilled technicians, and a lifetime warranty for your peace of mind.

2. Can a damaged ECU be repaired?

Yes, most damaged ECUs can be repaired. At ECU Fix LTD, we diagnose and repair issues caused by water damage, electrical failure, overheating, and more – restoring full functionality.

3. Is it worth fixing an ECU?

Absolutely. Repairing your ECU is often far more cost-effective than replacing it. With our lifetime warranty and expert testing, it’s a reliable long-term solution that can save hundreds.

4. How much does an engine ECU cost?

A brand new engine ECU can cost anywhere from £400 to over £1,200, depending on the vehicle. Repairing your existing ECU is usually the better value and faster option.

5. Can I drive my car with a faulty ECU?

We don’t recommend it. A faulty ECU can lead to unpredictable engine behaviour, poor fuel economy, or even complete breakdown. It’s best to remove and send it in for testing.

6. Can I fix my ECU myself?

Unless you have specialist tools and experience in automotive electronics, it’s not advisable. ECU repairs involve delicate components. At ECU Fix LTD, all work is done by trained technicians using advanced diagnostic equipment.

7. How to tell if an ECU is faulty?

Common signs include:

  • Engine not starting
  • Warning lights staying on
  • Random misfires or stalling
  • Loss of communication with diagnostic tools

We can confirm the fault with full bench testing.

8. Will a car still run with a bad ECU?

It might run temporarily, but not reliably. A bad ECU can cause loss of power, poor running, or complete failure. It’s safest to test and repair the ECU before continued driving.

9. How long does an ECU repair take?

Most ECU repairs at ECU Fix LTD are completed within 1–3 working days. We also offer courier collection and return for a fully hassle-free service.

10. Can a car start with a damaged ECU?

Sometimes – depending on the fault. However, it might struggle to start, run poorly, or fail entirely. It’s best to remove and send the ECU for diagnostic testing to confirm the issue.
