The EGR valve reduces pollutant emissions by reinjecting exhaust gases. It clogs up over time and needs replacing, at a cost of between €100 and €200, plus labour. Second-hand models cost between €15 and €75, but need to be cleaned thoroughly to ensure they last as long as possible.
The EGR valve, which is essential for reducing pollution by recycling exhaust gases, can quickly become clogged, especially in urban diesel cars. Simple methods, such as driving at higher engine speeds on the road, help to eliminate deposits. For in-depth cleaning, a garage is recommended. Specific additives can also prevent clogging, especially for urban driving. Avoiding short journeys and under-revving also helps.
Cordierite vs Silicon Carbide: A guide to choosing between DPF and high quality catalytic converters
If you need to replace your car's diesel particulate filter or catalytic converter, the choice between silicon carbide and cordierite is crucial. Opt for silicon carbide for better filtration quality and longer life. Cordierite, although cheaper, offers slightly lower performance. Choose quality materials to avoid premature breakdowns and optimise your vehicle's performance.
The article warns against buying second-hand catalytic converters for cars because of uncertainty over their condition, the risk of increased pollution, and the extra costs involved in removing them. It recommends opting for new catalytic converters to ensure better durability and performance.
Since the 1990s, the automotive industry has incorporated catalysts, AdBlue and measures to combat CO, HC and NOx in order to reduce its environmental impact, but the Euro 7 standards could pose new challenges.
Emphasis on the crucial need to identify the causes of particulate filter (DPF) or catalytic converter failures before replacing them, highlighting the importance of thorough checks, covering everything from sensors to glow plugs.
Modern, more environmentally-friendly cars require regular use to avoid breakdowns linked to particulate filters (DPF) and catalytic converters. The best way to prevent this is to drive long distances to keep these components in good working order, and to carry out regular maintenance.
The automotive industry is experiencing shortages, inflation and problems linked to the transition to electric vehicles. Parts prices are rising, with uncertainties about the future, despite solutions being considered, notably for catalytic converters.
Electric cars: no pollution when driving, but manufacturing and recycling emit CO2. The transition to electric cars is underway, despite the challenges.
For a used car in good condition, replacing the catalytic converter is essential. It improves performance, reduces pollution and reassures potential buyers. Choose a quality catalytic converter at an affordable price for a worthwhile investment.
