ECU faults we can investigate
An ECU fault can cause intermittent running problems, warning lights, communication errors or a vehicle that will not start. A proper diagnosis is essential before deciding whether the control unit needs repairing, replacing or whether the fault lies elsewhere in the vehicle.
- No-start and ECU communication faults
- Water-damaged control units
- Damaged ECU pins and connectors
- EGR and DPF control-module failures
- Engine, transmission and emissions fault diagnosis
The ECU repair process
Octane Tuning manages the job from initial diagnosis through to final testing. Customers can bring the complete vehicle to the Haddington workshop, or bring the removed ECU in for assessment.
- 1. Vehicle diagnosis and fault assessment
- 2. ECU removal, or receipt of the customer-supplied unit
- 3. In-house bench testing
- 4. Hardware repair through the separate ECU specialist where required
- 5. Refit, programming and vehicle testing as applicable
- 6. Final checks and warranty confirmation
In-house testing with specialist repair support
ECU hardware repairs are not carried out in-house. Octane completes the diagnostic work and bench testing, then uses a separate ECU repair specialist when internal electronic or hardware repair is needed. Octane can remove, refit and test the unit, or assess an ECU brought directly to the workshop.
Timescales, quotation and warranty
Turnaround depends on the fault, the ECU and whether specialist repair or replacement is required. A typical job may take from three days to two weeks. All work is priced by quotation following assessment.
A repaired ECU normally carries a three-month warranty. A new replacement ECU normally carries a 12-month warranty. The applicable warranty will be confirmed with the quotation. Most vehicle marques can be handled; Octane will advise promptly if a particular unit is not supported.
