DPF Removal and alternative options

Some vehicles will clearly indicate a DPF fault as shown below:
Unfortunately, not all vehicles have the specific DPF warning sign and will only illuminate the check engine sign as shown below.
If only the check engine light is on, get to your nearest workshop, have them do a diagnostic scan. The engine check light can indicate any problem regarding the injection system of the vehicle. So it is not to say if the check engine light is on that the DPF is at fault. That is why you need to have a diagnostic scan done to get the fault codes and description of the fault. We can also assist in doing a diagnostic scan for you.

Once established that it is the DPF causing the fault, or if you have a clear DPF warning, the following will apply to you:

Let's have a look at the options.

1. Buying a new DPF
2. Forced Regeneration
3. Cleaning of the DPF
4. Clearing fault codes with a diagnostic machine
5. Buying a used or second hand DPF
6. Removing the DPF


Replacing DPF

Buying a new DPF is ridiculously expensive. Most of us can not afford to buy a new DPF. To replace a DPF can cost as much as R100,000.00 with average prices between R40,000.00 to R50,000.00. The worst part is, if you drive the car for long enough it will simply get blocked again and you will have to spend the money again.


Forced Regeneration

Forced regeneration is an option and it will work if the DPF is not too blocked, but the average price is about R1500 to do this procedure. The problem is that it will not work at all if the DPF is blocked enough. Even if it does work, it will simply be a matter of time before the issue arises again. So, you will probably keep on spending the R1500 until the DPF is completely blocked and forced regeneration will not be an option anymore and this means money down the drain that you could have spent towards other options.


DPF Cleaning

Cleaning a DPF in the most part is a waste of money. Ask these companies if they are willing to free you of charge if it does not work? Even if does work temporally, ask them if they are willing to give you a guarantee and for how long? I highly doubt that they will be willing to give you a guarantee for let's say a year, 3 or 5 years and think about it, you will continuously spend money getting the DPF cleaned, throwing money into the endless DPF money pit.

One of the methods of cleaning a DPF is to pour a liquid in the exhaust system and then go drive the car aggressively, this in itself is ridiculous, if you have a blocked DPF the last thing you must do is drive the car aggressively. You have a very real risk of damaging the turbo amongst other components.


Clearing fault codes

Do not fall for this one. I have heard of people/companies charging R2000 just to clear the DPF fault codes or re-setting the DPF ash and soot counters. If the vehicle's DPF is blocked, this will not work. Just a few kilometres down the road the problem will return and I can guarantee you it will.


Buying a used or second hand DPF

This is a big no-no since its almost impossible to determine the state of used DPF. Imagine spending thousands of Rands to find out after installing the used DPF you have the exact same problem or the problem reappears after a few months.


DPF Removal

Removing the DPF completely, so getting rid of the physical diesel particle filter and the DPF function on the vehicle's engine control unit (ECU) is the option I prefer and suggest. We give you a lifetime guarantee and this means you will never have to throw money into the endless DPF money pit again. To remove and delete the DPF is a fraction of the cost to replace the DPF. Pricing range from R4250 and this includes the removal of the actual filter as well as the software modification to delete the DPF function from the vehicle's ECU.

Please note, removing the DPF is a 2 part process, you can NOT just remove the actual filter and think the problem will be solved. This is because the DPF system is monitored by the engine control unit (ECU). You can also not just do the software modification without removing the actual diesel particle filter, this will cause damage to the turbo and other engine components since the blocked DPF is restricting the flow of exhaust gasses severely.

Are there any negative effects by removing the DPF? No, in general, the engine is much happier without the DPF. Remember, vehicle manufacturers do not wish to install catalytic converters or diesel particle filters systems, but they do not have a choice and forced to do so because of 1st world emission laws.

Will the vehicle smoke...the short answer is no. if the vehicle is in good condition, you may see a bit of smoke on startup or when you do a hard pull off you may see a puff of smoke. If components such as injectors are NOT in good condition anymore, yes then the vehicle will smoke.

The conclusion is if you want to avoid the endless DPF money pit, the best option is to completely remove the DPF system. You will never have to worry about the DPF system, regeneration or buying expensive DPF sensors when they fail.
