If the ECU is not repairable, and should a replacement be available, a £50 surcharge will apply.

If your unit is repaired or a replacement is supplied the test fee is also waived.

Please ring our customer service team for more details.
Notes: Simtec 71.1 : We require the ignition key and immobiliser (key transponder chip pick-up) box to test. We can reset the security code or code your unit to an immobiliser box and key. If fitted to a Corsa and a replacement ECU is supplied, you will need to program the body computer and instrument panel to the new ECU. This can be done with the 4 digit security code and appropriate diagnostic equipment (Tech 2 or VAUX-COM). Please let us know if you require us to read the security code from the ECU.
Simtec 71.5/6 (Vectra-C or Astra-H) : We require the ignition key to test. We can reset the security code so that it can be coded to the car using appropriate diagnostic equipment (Tech 2 or VAUX-COM). When replacing the ECU, the Column Integrated Module (CIM) must be programmed to the new ECU.

Common Faults: Intermittent or poor running when vehicle gets warm.
No response to lambda sensor.

NB: These units are often beyond repair due to the internal wire bonds being prone to failure. We can offer a test on these units however if the bonds have started to fail the test process may put added strain on the bonds and the unit may develop additional faults.
