Finding your engine
The engine size is on your V5C, and most cars carry the badge on the boot lid. Where a model was sold with several power outputs of the same engine, they are listed separately above because the files and the gains are different.
Get it wrong and nothing is lost. We check the engine against the car before we write anything to it.
