How to Prepare My Engine for the Technical Inspection?

During the emissions test, the levels of various gases are measured and must not exceed a certain tolerance threshold. This threshold is defined based on the equipment of your vehicle. Indeed, particulate filters, EGR valves, and other catalytic converters that help reduce emissions are not always present in older vehicles.

With diesel cars, inspectors pay close attention to fine particles, especially since July 1, 2022. In Belgium, since that date, vehicles that meet the Euro 5a environmental standard (or newer), and are therefore equipped with a particulate filter, are tested very rigorously. Why? Because these particles are particularly harmful to health and the environment. The problem is that without proper maintenance or with repeated short trips, particulate filters often suffer from defects.

Fortunately, the particulate filter, like other technical components related to engine depollution, can be maintained using various additives. Bardahl has developed chemical solutions for both diesel and gasoline engines, which can be used preventively or simply before the technical inspection. These additives help clean mechanical parts (particulate filters, EGR valves, catalytic converters, injectors, valves, etc.) and reduce potential pollutant emissions.

The advantage of these additives that clean your engine components is that they are easy to use. Either they are poured directly into the fuel tank during a fill-up, or they are added to the engine oil sump. Everything is very simply explained on the label of each product. If you prefer, you can ask your mechanic to use Bardahl products—they will know what to do.

And if you want a deep clean of your vehicle's engine, be aware that there are specialized engine depollution centers. By leaving your vehicle with an eco-cleaning expert, the components prone to clogging will be intensively cleaned without disassembly, thanks to a Bardahl cleaning station. The process takes only 30 minutes to 2 hours and should ideally be repeated every 20,000 km. This rejuvenating treatment for your car's mechanics will not only help you avoid replacing costly parts but, more importantly, prevent you from failing the technical inspection!
