Independent specialist Baz Meredith provides a comprehensive guide to addressing heavily blocked DPFs, underscoring why technicians must focus on fixing root-cause emissions faults instead of opting for DPF deletion.
It highlights the importance of rigorous component verification after Baz encountered an immediate failure with a new aftermarket EGR valve.
Beyond the initial repair, the video offers essential technical advice on handling modern low-voltage glow plugs, warning that direct 12V testing will cause instant destruction.
Baz illustrates a methodical approach to chemical DPF cleaning, carefully managing the procedure to mitigate risks of engine damage while monitoring live pressure data.
Finally, the video debunks the “Italian tune-up” myth, demonstrating that maintaining steady speeds and temperatures is more effective for successful active regeneration than high-RPM driving.
