🚗 VW Tiguan 2.0 TDI – DPF Chemical Clean Success 🚗
This VW Tiguan came to HCR Performance suffering from a restricted DPF.
As with every vehicle, we started with a full diagnostic assessment before recommending any cleaning. A blocked DPF isn’t always the root cause, so it’s important to verify that all supporting systems are functioning correctly.
✅ DPF Differential Pressure Sensor Tested
✅ Exhaust Gas Temperature Sensors (EGTs) Checked
✅ EGR System Operation Verified
✅ Live Data Analysed
✅ Fault Codes Checked
✅ DPF System Health Assessed
Our testing showed a DPF pressure reading of approximately 64 mbar at idle, indicating significant restriction within the filter.
After analysing the live data and confirming all relevant sensors and components were operating correctly, we carried out a professional chemical DPF clean.
📊 Results after cleaning:
✅ Less than 10 mbar at idle
✅ Approximately 68 mbar at 2500rpm
✅ Improved exhaust gas flow
✅ Reduced DPF restriction
✅ DPF able to regenerate more efficiently
The images show the amount of carbon contamination and residue removed during the cleaning process.
At HCR Performance, we don’t just clean DPFs—we diagnose the vehicle first to ensure cleaning is the correct solution. This helps prevent unnecessary costs and gives customers confidence that the underlying cause has been properly assessed.
