Our first task is to identify the cause of your DPF becoming blocked. You will then be advised of the cost of repair, should you wish for us to proceed with the work. It is often the case that cleaning is not even required.
We at Central Garage Carcroft will reset any error codes using the same procedures that the main dealers use and perform an emergency regeneration to ensure that the complete DPF system is operating correctly so the problem won’t happen again.
To clean the DPF on most vehicles costs £265, including resetting the soot level calculation in the ECU if required. Any repair work needed before we at Central Garage Carcroft can clean the DPF will be advised once an initial diagnosis is performed.
Your DPF is cleaned using a specialist process we at Central Garage Carcroft have developed. It achieves similar results to the similar results to the normal regeneration process that cleans the DPF under normal driving conditions. When soot in the DPF reaches a certain level the ECU will not allow the DPF to regenerate due to the risk of fire. The cleaning method we at Central Garage Carcroft practice cleans even the most badly sooted DPFs returning the vehicle to its normal working condition.
These problems are often the result of the intake system has becoming restricted due to a buildup of carbon deposits.
Excess soot and carbon gums up piston rings and reduces compression in the process. The injector nozzles then become contaminated with a hard deposit that affects atomisation of the fuel, affecting emissions and often producing more soot.
Cleaning one or two components such as EGR or DPF may have a short-term effect but effectively this treats just the symptom, not the problem.
It is entirely normal for your DPF warning light to appear - it is simply advising you that the DPF needs to regenerate itself. Your owners manual will include instructions for how to do this. If you can't find these instructions, the following process will work for most cars.
