We recommend using Redex DPF Cleaner with every 2-3 tanks of fresh fuel. This will prevent the DPF from ever becoming blocked, so no more panicking when the warning light appears.
Alternatively, you can add a shot of DPF Cleaner when the light comes on. Add a dose to your car’s fuel tank, drive as normal, and you should find that the light switches off without the need for that inconvenient trip to the motorway.
