MUST READ: Diesel Emissions Testing Info

This week we are taking a look at the smoke limits for Diesel vehicles.

We will also be taking a look at the Euro emissions for Diesel and Petrol cars.

Vehicles first used before 1st July 2008

The smoke limit will be:
– 2.5m-1 for a non-turbocharged engine
– 3.0m-1 for a turbocharged engine
– The level specified on the manufacturer’s plate if lower

Vehicles first used between 1st July 2008 and 31st December 2013

The smoke limit will be:
– The level specified on the manufacturer’s plate if lower
– 1.5m-1

Vehicles first used on or after 1st January 2014

The smoke limit will be:
– The level specified on the manufacturer’s plate if lower
– 0.7m-1

The manufacturer’s plate means either the VIN plate or a separate plate or sticker, which is likely to be within the engine compartment. The plate or sticker may be marked 24 R followed by a number to indicate the smoke limit (such as 0.24 in the example below). It’s usually displayed in a box and often positioned in the bottom right corner of the VIN plate.
