Diesel smoke meters should have been upgraded before 20 May 2018. Equipment manufacturers have now carried out all orders made for upgrades and replacements.
You must stop testing all vehicles immediately if your equipment has not been updated or replaced.
Check if your diesel smoke meter meets the requirements DVSA is aware that there’s been a problem with some devices after the upgrade. For example, the entry and use of a plate value to assess the test standard. DVSA is working with individual manufacturers and the Garage Equipment Association (GEA) to investigate and resolve issues. If your diesel smoke meter does not appear in the list, or if you have any questions about the upgrade, contact the GEA.
