How to find the manufacturer’s plate value
The ‘plate value’ is the emission limit specified by the vehicle manufacturer. You’ll find it either on the vehicle manufacturer’s plate or on a separate plate or sticker, usually in the engine compartment. If it’s on the manufacturer’s plate, it will be a number (usually in a box) and often at the bottom-right corner of the plate. If the plate value is on a separate plate or sticker, it should show:
an ‘E’ in a circle followed by a number (representing the country that granted the approval)
the number 24 followed by the letter ‘R’ and the approval number
The plate value will be in a box. Less commonly, the plate value appears in the top right corner of the emissions plate after the number 24. Example 1 In this example, the plate value is 0.52m-1. Example 2 In this example, the plate value is 1.82m-1.
