The risks, the benefits and why DPF Fixer LTD is your best solution
A forced regen is the process most mechanics will use to attempt to clear your blocked diesel particulate filter (DPF) when passive or active regeneration attempts have failed.

Modern diesel vehicles can and should automatically regenerate their DPF in normal driving conditions such as long motorway journeys where exhaust temperatures are high enough to burn off trapped particles. Unfortunately short urban trips, stop and go driving and prolonged idling will prevent your vehicle’s DPF from regenerating causing it to eventually block altogether.
Forced Regens, Good or Bad?
For £85-£100 a Forced Regen might offer some temporary relief for your blocked DPF, however this tends to last for a couple of weeks or less. The temptation is to continue using this “quick fix” method but the truth is, multiple forced regenerations over a relatively short period can cause very serious damage to your DPF system as well as the engine itself.
Here’s How:
- Thermal Stress: During a Forced Regen your DPF heats up to extreme temperatures north of 600°C in order to burn off soot. Repeating this process too many times causes cracking and thermal damage to the DPF
- Engine Wear and Tear and Oil Contamination: Part of the process of a forced regen is to inject excess fuel in order to increase exhaust temperatures. When this happens too frequently it will lead to fuel dilution in the engine oil which reduces lubrication causing premature engine wear and sometimes failure
- Continued Blockages: If your DPF is blocked with ash residue, forced regens will not be effective and the issue will remain. Continuing to force the DPF to regenerate will worsen the problem and cause serious damage
- Injector and Turbocharger Damage: Multiple forced regenerations can overload the turbocharger, fuel injectors as well as other expensive engine components with the extreme heat being generated. This can lead to costly repairs
- Fire Risk: During the forced regeneration process flammable material in and around the exhaust system can catch fire due to the intense heat being generated. This is potentially a very serious hazard, especially for vehicles parked in enclosed spaces.
