Auto Clinics High Wycombe offers DPF removal and ECU reprogramming services. Please note: DPF removal for vehicles used on public roads is illegal under UK law and will cause an MOT failure. This service is intended solely for off-road, competition, and track-use vehicles.
DPF removal is illegal for vehicles used on public roads in the UK under the Road Vehicles (Construction and Use) Regulations 1986. A vehicle with a removed or bypassed DPF will fail its MOT emissions test. This service is provided exclusively for vehicles used off-road, in competition, or on private land, and must not be used on public highways.
For motorsport, track days, agricultural, and off-road competition vehicles, DPF removal can improve performance, reduce maintenance requirements, and eliminate DPF-related restrictions. Our technicians carry out the physical removal and the necessary ECU reprogramming to ensure the vehicle runs correctly without the DPF system.
Simply removing the DPF without reprogramming the ECU will trigger persistent fault codes and warning lights, and may cause the engine to enter limp mode. Our specialist equipment allows us to remap the ECU to remove the DPF monitoring functions, resulting in a clean, fault-free system appropriate for your off-road or competition application.
Our DPF removal service includes physical removal of the DPF unit, ECU reprogramming to disable DPF monitoring and regeneration cycles, deletion of related fault codes, and a road test (on private land) to confirm correct operation.
We provide a document confirming the vehicle's intended off-road or competition use, which we recommend retaining alongside your vehicle's records.
