Can a DPF system be bypassed?
While it’s not illegal to remove a car’s DPF, it is illegal to drive without it if one should be fitted. It’s believed some drivers whose DPFs become blocked are simply bypassing the filters by removing them rather than paying for a replacement, which typically costs around £1,000.
How do I unblock DPF?
DPF cleaning is the most effective way to clear a blocked DPF filter. Flash cleaning a blocked DPF will completely remove the build-up of soot and exhaust residue, ensuring increased performance and economy. Flash cleaning your DPF completely removes PM10 residues, oil and cerium.
Is DPF Delete legal?
Is a DPF delete legal? We had a yarn with the NSW Environmental Protection Agency, and they confirmed it is absolutely illegal (because you’re screwing with the pollution gear on a vehicle), and the accompanying on-the-spot fine for driving a vehicle with a DPF delete is $300.
What does DPF do to a diesel particulate filter?
The Diesel Particulate Filter traps the harmful diesel gases that gets cleaned regularly by a process called DPF regeneration. The collected diesel soot particles are burnt off at high temperatures, which results in an “ ash-like ” after product.
What should I do if my DPF is not working?
Check that the EGR system is working correctly; 4. Check that the vehicle has the correct specification engine oil; 5. Check the Eolys/Cerine additive (active system); 6. When the DPF filter load reaches a predetermined level, the ECU activates a regeneration process to increase the DPF temperature to over 550˚C.
What is the fault code for DPF failure?
d) If the coil and engine management light is on with loss of power, ‘limp home mode’ will engage with a maximum of 3000 RPM. The fault code will read: ‘DPF soot loading too high’. ‘Forced regeneration’ is now required.
What does it mean when the DPF light comes on?
The majority of vehicle manufacturers have the same warning light sequence but you should always check the vehicle handbook to be safe. The sequence generally consists of the following steps: a) If the DPF light comes on (see image above) this means ‘regeneration’ is needed. b) Once again, read the handbook for instructions.
