Advice on ECU Diagnosis & replacement.

1 - Scan the vehicle with a diagnostic scanner & record fault codes - rectify any faults recorded here first & check the wiring for faults. 2 - If your ECU has'No communication' with a diagnostic scanner it is essential that you check relevant fuses and consult a wiring diagram for your vehicle and verify the power supply & test the wiring to your ECU - particularly test power supply relays (Engine control relay). 4 - If your fault is a cylinder misfire please check spark plugs / leads / coil / injectors and wiring faults / headgasket faults etc before ordering, if these have been checked or replaced then it is important to check inlet manifolds for leaks, engine compression & perform a vacuum gauge test to check for valve problems.

If you are purchasing an ECU marked as'Plug & Play - Immo off' This means that the immobiliser has been removed from the ECU & will start & run as normal without the need of a transponder key. If for any reason the car does not start & run correctly you can send the ECU back with your original ECU for bench programming (Data transfer), once bench programmed your immobiliser will be re-installed & you will need a functioning immobiliser key. Do not send any other items such as keys etc unless specifically asked to do so.
