2003 PEUGEOT 807-HDI ENGINE. 90000MILES. ANTIPOLLUTION MESSAGE ON SCREEN- CAR REGISTERS EXHAUST PRESSURE SENSOR OUT OF LIMITS, GOES INTO "GET YOU HOME MODE' ie WILL NOT THROTTLE OVER 2500 RPM. SO FAR.... FUEL ADDITIVE PUMP AND RESERVOIR CHANGED WITH NEW ADDITIVE. EXHAUST FILTER CHANGED TO RE-SET SYSTEM AS NEW.. EXCEPT SYSTEM WILL NOT REMAIN RE-GENERATED AFTER RE SET.- TRIPS OUT AFTER 5000 MILES WHICH I AM LED TO UNDERSTAND IS THE FREQUENCY FOR THE ANTIPOLLUTION SYSTEM TO INJECT FLUID INTO EXHAUST SYSTEM WHEN HOT ENOUGH. VICIOUS CIRCLE OF RE- SETTING SYSTEM. CODES INDICATE THAT THE PARTICULATE FILTER IS BLOCKED-STILL! AFTER VARIOUS BYPASS ATTEMPTS TO TRICK THE COMPUTER INTO ACCEPTING THE NEW FILTER THE MOST SATISFYING ATTEMPT WAS TO DRILL A 19MM HOLE THROUGH THE HONEYCOMB FILTER! WORKED FOR A WHILE AND MADE ME FEEL MUCH BETTER. I AM INFORMED BY MY LOCAL ENGINE SPECIALIST THAT THIS PROBLEM IS NOT UNCOMMON. IDEALLY LOOKING TO DISABLE THE ANTIPOLLUTION SYSTEM WITHOUT THE COMPUTER RESTRICTING THE FUEL SYSTEM IN EMERGENCY MODE. I AM TOLD THAT SOME ELECTRICAL FAULTS AS SIMPLE AS A BREAK IN A PARTICULAR WIRE CAN HAVE THE DESIRED EFFECT. THE PERFECT SOLUTION TO MY PROBLEM IF ONLY I COULD IDENTIFY THE WIRE. THE LAST 10000 MILES HAVE BEEN ECONOMICAL IF SLOW WITH THE SYSTEM AS DESIGNED BY PEUGEOT, IE ALL MODIFICATIONS REMOVED. ANY IDEAS?
