SOFTWARE SOLUTION
DPF OFF
Clogged particulate filters, endless regeneration drives, limp mode: for export and motorsport vehicles we deactivate the DPF system completely in the engine software.
The diesel particulate filter clogs up with soot and ash — especially on short trips. Frequent regenerations increase fuel consumption, dilute the engine oil and often end in limp mode or a four-figure replacement bill.
With the software deactivation, regeneration, the soot-load model and all associated sensor paths (differential pressure, exhaust gas temperature) are shut down consistently — the engine runs stable long-term, with no fault codes.
Complete system mapping
Soot-load model, regeneration logic and sensor plausibility checks are fully deactivated.
No limp mode, no warning light
All diagnostic paths are adapted — the instrument cluster stays clean.
Longer oil life
No more post-injections — no fuel dilution of the engine oil.
Combinable with EGR OFF
On request, done in the same session with EGR deactivation and power optimization.

LEGAL NOTICE
Deactivating or removing the diesel particulate filter is not permitted within the scope of the German road traffic regulations (StVZO) and voids the vehicle's operating permit. This service is offered solely for export vehicles and for motorsport vehicles used off public roads. By placing an order, you confirm that the vehicle will be used exclusively outside the scope of the StVZO.
