What happens when your particulate filter reaches us
We diagnose the filter to see whether it is genuinely blocked or the sensor is triggering the light
We clean it at very high temperature: this burns off soot and ash and restores the exhaust gas flow
We carry out an optical and instrumented check for blockages, structural damage or flaws in the channels
We tell you whether the filter can be saved by cleaning or needs more than that
We send your filter back cleaned and tested, with a 12-month guarantee against any problem
