ECU Repair & Programming in Perth

Car won’t start, cutting out, or showing a “no communication” error? The fault is often the engine control unit (ECU, also called ECM or DME), and it doesn’t always need replacing. At Eurotronix in Willetton, we diagnose and repair ECUs for European, Japanese and American vehicles, usually for far less than a dealer replacement. Inspections start from $175, and every repair is backed by a 12-month warranty.

 

Why you can’t just swap in a second-hand ECU

Most modern ECUs store immobiliser and key data tied to your car. A used unit from a wrecker won’t start the vehicle until it’s programmed to match, which is why dealer quotes for new units can run so high. We repair the ECU you already have, so your existing keys and settings keep working. If it’s beyond repair, we can program a used or replacement unit to your vehicle (you supply a compatible unit).

 

Signs your ECU may be failing

• Engine won’t start, or cranks but won’t fire

• Engine cutting out while driving

• No spark, or loss of injector or fuel pump signal

• Erratic idle or excessive fuel use

• Check engine light with no fault codes, or “no communication” with the ECU

• Car stuck in limp mode

• Water damage or a failed jump start

These symptoms can also come from sensors or wiring, so we recommend inspecting before a repair.

 

How our ECU repair works

1. Inspect. We test the ECU to confirm the fault is in the unit, so you don’t pay for the wrong repair. Inspections start from $175.

2. Quote. We tell you what’s wrong and what the repair involves before any work goes ahead.

3. Repair and program. We repair the ECU and match it to your vehicle, with keys and immobiliser working as normal. Turnaround depends on the fault and parts availability, and we’ll give you a realistic timeframe after the inspection.

4. Warranty. All ECU repairs carry a 12-month warranty.
