AUDI A4 2.0L TDi 2008 35k
Lack of power, engine management light on and DPF warning light on, fault code stored for DPF fault. Vehicle check at dealer showing the DPF filter soot loading 126%, recommending a new DPF is fitted.
The fault was cured by adding 2 x DPF Cleaner and Regenerator into the fuel tank and carrying out a 20-30 mile road test at 50-60 mph 2,500 rpm. After the road test the DPF was re-checked showing the filter soot loading at 18% and power restored.
