Where do I find the engine code?

The engine code is usually in one of three places:

• The registration document — under engine type or engine number.
• The engine itself — cast or stamped into the block, often at the gearbox end or under the cover.
• A workshop — a garage reads the code from your VIN in the manufacturer’s catalogue in a couple of minutes.

If you cannot find the code, send us the VIN and the registration number with your enquiry and we will look it up for you.
