Can a DPF be removed and cleaned?

Another option is to clean it yourself with an additive. With Lindemann's Total Care Diesel you can clean your DPF yourself. This product lowers the combustion temperature of soot, making it easier to burn. It also contains a very high level of active cleaning agents.

Is removing DPF a good idea?

Removing the filter doesn't affect the car's performance, and some motorists even state they achieve better fuel economy and engine performance without one.

Can I remove DPF myself?

It has been known for people to remove DPF filters themselves, but non-professional DPF replacement will almost certainly breach requirements under the Road Vehicles (Construction and Use) Regulations and the car will then be illegal for road use.

What happens if you take the DPF out?

Without the DPF, a diesel vehicle's ECU will not receive the correct sensor information relating to minimum and maximum allowable back pressures, which will result in error codes and probably the vehicle running in “limp” mode.

Can a fully blocked DPF be cleaned?

Some garages can clean blocked DPFs, in a process called forced regeneration. This usually costs around £100 and, while it's not a 100% guaranteed fix, it's usually successful in removing the excess soot and allowing the DPF to work and automatically regenerate again.

Can a blocked DPF damage Turbo?

A blocked DPF can force exhaust gas through the smallest of gaps, including the clearances in the bearing housing VNT lever arm and turbine housing waste gate mechanisms. If this occurs, carbon build up in these mechanisms can restrict movement of the levers affecting performance of the turbo.

How much does it cost to clean DPF filter?

Cold starts also create the need for more frequent DPF cleanings, which shorten DPF effectiveness and, ultimately, lifespan. Factor in downtime for cleaning DPFs and replacement costs can range between $2,500 to $8,000 per vehicle.

Will my car smoke if I remove the DPF?

In most cases, the automated software won't delete these parts of the file, but then leaving part of the DPF file in place will also bring problems such as the vehicle falling back into limp mode, the DPF light coming back on, excessive smoke and as a result of this, an MOT Failure.

Can a blocked DPF damage the engine?

Blocked DPFs wreak havoc with the delicate balance of your engine by preventing the normal venting of gases, which causes a variety of engine issues, as described above.
