Check the cause and filter condition before deciding between regeneration, cleaning and replacement. The method and work location are agreed before the job.
Symptoms, driving profile and regeneration history are recorded before cleaning. Differential-pressure and temperature readings are checked for plausibility so that sensor or engine problems are not confused with filter loading.
The decision depends on filter condition, loading and the cause. Forced regeneration is not appropriate for every fault; a damaged filter may need replacement.
On-vehicle cleaning and cleaning a removed filter are different procedures. The suitable and available method, any removal work and work through AVM in Ibbenbüren are clarified before the job.
Recurring DPF problems can require further diagnosis of temperature control, sensors or combustion. Cleaning alone is not a promise that the filter will remain fault-free.
Final checks depend on the vehicle and cleaning method. Available pressure, temperature and fault data are assessed again. Diagnosis, cleaning and lawful repair take priority; removal of required emissions equipment is not offered as a public-road solution.
Local advice, vehicle assessment, diagnostics and suitable software work. We check the options for your vehicle. Dyno testing, development and extensive workshop work through AVM in Ibbenbüren. We agree on the scope and location before your appointment.
