EEC, a leading manufacturer of diesel particulate filters (DPFs), recently supported a garage facing a challenging emissions issue with a Vauxhall Vivaro van. The vehicle had entered the garage with multiple DPF fault codes and an emissions warning light.
A new EEC DPF was installed, and initial fault codes were cleared. However, the customer returned shortly after with the same issues. A common misconception in the industry is to blame the aftermarket component without considering any other factors. In this instance, the root cause was incorrect post-installation procedures.
EEC’s technical support team intervened, emphasising the critical steps often overlooked in DPF replacement. These include an engine oil and filter change, ECU reset, and crucially, a forced regeneration. This process is essential for the ECU to recognise and adapt to the new DPF.
The team at EEC also highlighted the importance of addressing underlying engine issues that can contribute to DPF problems. These can include carbon build-up on injectors, valves, and turbochargers can hinder DPF performance. EEC’s 6-in-1 DPF cleaner is designed to mitigate these issues by reducing carbon deposits and optimising combustion temperatures.
This case study underscores the importance of technical expertise and product quality in the aftermarket. EEC’s commitment to supporting its customers with comprehensive technical guidance and high-performance DPF solutions was instrumental in resolving this issue.
By following EEC’s recommended procedures and utilising their advanced products, workshops can enhance their DPF replacement services and deliver superior results to their customers.
