Engines were used over a wide model range. Publish the engine number and VIN here and I am sure someone can check it for you.

Does the engine number match that on the V5?

If the engine was changed then the DVLA should have been notified in case it alters the RFL liability.

Engine numbers can be in various places, you will just have to get a torch and look. The number is usually on a side of the block or other flat surface.

The VIN would be a good starting point to establish which model of engine your car came with from the factory.

Then, you'll need to find the engine number, and the first 3 digits will be the engine model code.

ENGINE NO MAY BE ON THE ENGINE BLOCK BEHIND ALTERNATOR OR ENGINE MOUNT

YOU WILL HAVE UNDOUBTEDLY HAVE TO CLEAN THE BLOCK UP TO SEE THE NUMBER AT ALL!
