Peugot anti-pollution fault - a solution!!?

I found a guy in Sheffield that cuts the particulate filter out of the exhaust, welds up the hole then tells the ECU it doesnt exit any more - result NO problems, just gone through the MOT and not a problem cost £350 but well worth it when those plonckers at Peugot dealerships just want to charge you £100 to tell you the fault code not actually fix it.
