• The 'Unit supplied + cloning service (Exchange unit)' option is for the both the supply of a secondhand unit & the programming service (Cloning - Data transfer from your unit to this donor unit) To do this you will have to send us your old unit. Once we have received your old unit we will transfer the immobilizer data from your old ECU to this supplied unit & return you a replacement unit fully programmed to your vehicle. This unit will then plug straight in and work on your vehicle with your existing keys etc  with no further programming necessary. Your vehicle mileage etc will be unaffected by this process & will still display your vehicles correct reading. You will not have to program keys / central locking keyfobs etc after installation. *In most cases we can extract the necessary data whether your original ECU is completely dead with 'No communication' with a diagnostic scanner*.
• The 'Unit supplied only - No service required' option above is for the ECU to be supplied without the programming service included - You will be responsible for the programming yourself - Please only choose this option if you have access to necessary programming equipment & competent in its use.
• The 'Cloning service only' is for a Cloning (Data transfer) service BY POST ONLY – We are NOT supplying the ECU!! If you have a faulty ECU (Electronic Control Unit) on your vehicle, for example it may be water damaged or have a blown component and are looking to replace the ECU you may be aware that you cannot simply remove an ECU from another vehicle & install it onto yours as the ECU is 'Locked' to a different vehicles electronic / immobilizer system. We have the solution! Simply send us your original (Faulty) ECU & the donor (Replacement) unit & will will transfer the data from your original to the replacement enabling the used unit to work on your vehicle with no further programming necessary. *In most cases we can extract the necessary data whether your original ECU is completely dead with 'No communication' with a diagnostic scanner*. Once the donor unit has been programmed (Cloned) your vehicle will then start & run, the mileage display & the central locking etc will be unaffected & operate as it should. We are not supplying an ECU with this option.
