If the warnings are still ignored and the soot levels increase to around 95% you can expect the vehicle to be put into limp mode by the ECU in order to protect the engine from damage due to the increased back pressure caused by the blocked DPF. At this point the DPF cannot be regenerated and will need to be replaced. Has the vehicle been serviced recently or has the oil been changed? If the vehicle has recently been serviced it is worth checking that the correct type of oil has been used. Most DPF vehicles require a special type of low ash oil, and using the incorrect oil can lead to problems during the regeneration process.If the vehicle uses a fuel additive system to aid regeneration it should be checked that the additive tank has been filled. The additive tank is normally located near the fuel tank. Diagnostic Checks & Installation Before fitting the DPF diagnostic checks should be carried out with an appropriate fault code reader to establish any codes held within the ECU. Comprehensive testing of the components listed below should also be carried out as a fault with one of them either alone or in combination could lead to DPF failure. Be aware that an unresolved fault with the vehicle that illuminates the engine management light will usually prevent the regeneration process from initiating and therefore the DPF will become blocked. DPF Pressure Pipes & Sensors checks should be made to ensure all pipes are free from damage or blockages and the differential pressure sensor is working correctly. It is best practice to replace the differential pressure sensor when fitting a new DPF. Oil Level if the oil level is high this is a sign that it has been contaminated with fuel from failed regeneration attempts. The extra fuel intended to increase the exhaust temperature can find its way into the engine sump, contaminating the lube oil and sometimes leading to a breakdown as the engine can start to run uncontrollably on its sump oil. An oil change will be necessary.
Oil Specification check that the correct low ash oil has been used. Fuel Additive (where applicable) check the level of the fuel additive, and fill the additive tank as required. There is normally a manufacturers procedure that must be followed to reprogram the ECU to the new additive level. Sensor Checks check all sensors (exhaust gas temperature & oxygen sensors) to ensure that they are operating correctly.EGR System check the Exhaust Gas Recirculation valve is working correctly, is not blocked and is sealing correct. As a minimum the EGR valve must be removed, cleaned and checked before replacing the DPF. A faulty, clogged or leaking EGR valve will cause the DPF to become blocked. The Following Items Must be Checked air flow meter, engine and turbo wear, injectors (in case they are leaking or over fuelling) turbo hoses and the intercooler must be checked for leaks, correct glow plug & glow plu controller operation and the main engine ECU should also be checked for any malfunctions. DPF Installation & Set Up Once the fault that caused the previous DPF to fail has been rectified the new DPF can be fitted. The new DPF should be fitted loosely to line it up correctly with the rest of the exhaust system before tightening it up. An appropriate diagnostic tool will be required to reset the ECU in accordance with the manufacturers guideline. This includes telling the car that a new DPF has been fitted, resetting the ash counter and calibrating the differential pressure sensor.
Using leaded or lead replacement fuel will plug up the monolith and cause it to stop working. A similar thing will happen if fuel additives are used that are not suitable for use with a catalytic converter. Oil Fouled This is caused by oil getting into the exhaust system and contaminating the catalytic converter. The most likely cause would be a failing seal or gasket. Broken Substrate The monolith is usually broken when it is impacted by an object or when it suffers a sudden change in temperature.If the catalytic converter suffers road damage the monolith inside can be cracked due to it being crushed by movement of the steel can. The use of exhaust paste before the catalytic converter can cause the monolith to break.
When the exhaust paste has hardened small pellets may break away and shoot into the catalytic converter. The monolith will gradually be destroyed by these pellets and break down.
The catalytic converter can also be damaged by excessive engine vibration. Overheating There are many problems that can cause the catalytic converter to overheat or fail. The most common cause is unburned fuel entering the catalytic converter. Faulty spark plugs or ignition leads will cause the engine to misfire sending unburned fuel into the catalytic converter leading to overheating and failure. A Oxygen Sensor An oxygen sensor collects readings and sends information to the electronic control unit.This information is used to control the air/fuel mix. If the oxygen sensor is faulty the air/fuel mix will not be corrected and excess fuel will enter the catalytic converter causing it to overheat and fail. B Fuel Injection Systems If a fuel injector is leaking internally or dribbling fuel into the engine the excess fuel will enter the exhaust system causing the catalytic converter to overheat and fail. C Map Sensors Map Sensors tell the electronic control unit the load the engine is under and the amount of fuel entering it. If a map sensor fails it causes the engine to run too rich which causes the catalytic converter to overheat and fail. D Carburettor Systems A worn or defective carburettor can cause a catalytic converter to overheat and fail. Problems such as improper float or air/fuel mix adjustments, worn metering rods or a faulty choke system can cause too much fuel to enter the engine and then the exhaust system causing the catalytic converter to overheat and fail. E Canister Purge Valve Control This vacuum operated valve vents fuel vapour from the carburettor bowl to the charcoal canister. If the vacuum is breached the charcoal canister will flood causing the air/fuel mixture to become too rich which will cause the catalytic converter to overheat and fail. If your vehicle has failed the MOT emissions test or your catalytic converter is rattling or blocked you will need to include a scanned copy of an engine emissions report. The most common causes of a blocked DPF are listed below. A newly fitted DPF will block if the fault that caused the original filter to block was not rectified prior to fitting the replacement. After installation the main Electronic Control Unit must be readapted to the new DPF. If the correct setup process is not completed the regeneration process will not initiate and the DPF will become blocked. A fault with an associated component i. Differential pressure sensor, exhaust gas temperature sensor, exhaust gas recirculation valve will prevent the regeneration process from initiating and the DPF will become blocked.
When the DPF light illuminates you must follow the instructions in the owners hand book, failure to comply could result in a blocked DPF. A DPF that uses an additive to assist in the regeneration process must never be driven without this fluid as this could result in a blocked DPF. On most vehicles the regeneration will not take place when the fuel light is on or if there is less than 10 litres of fuel in the tank.The use of the incorrect grade and type of engine oil can cause a DPF to become blocked. It is not advisable to run a DPF equipped vehicle on Bio-Diesel fuel as this can block a DPF. The style of driving or type of journeys covered that do not allow the vehicle to meet the correct parameters for active regeneration will cause a DPF to become blocked.
