🚗 LACK OF POWER? ENGINE LIGHT & DPF WARNING ON?
This vehicle came into us suffering from a lack of power, with both the engine management light and DPF warning light illuminated.
After carrying out some checks and looking at the live data, we found the DPF soot content and differential pressure were both high. The next step was to find out why the DPF was struggling.
🔧 We traced the problem to a split boost pipe!
A split boost pipe causes a loss of turbo boost pressure, meaning the engine isn’t getting the correct amount of air. This can lead to poor combustion and increased soot production, putting extra strain on the DPF and potentially causing it to become blocked.
✅ Replaced the split boost pipe
✅ Cleaned the DPF and cleared the accumulated soot
✅ Checked live data and confirmed everything was looking good
✅ Carried out a service
Another vehicle back to running as it should!
💡 A little DPF fact: Your Diesel Particulate Filter (DPF) captures soot from the exhaust and periodically burns it off during a process called regeneration. If something causes excessive soot build-up, or regeneration can’t complete properly, the filter can become restricted.
The important thing is to find the underlying cause rather than simply cleaning the DPF and hoping for the best!
