On modern DAF trucks, the system that measures pressure before the turbine (BPV — Bypass Valve) plays an important role in regulating engine operation and protecting the turbocharger. However, after disabling or modifying certain systems (such as AdBlue, EGR, etc.), the standard pressure monitoring can cause errors, power limitations, or trigger emergency modes.
With TruckTools, you can disable pressure measurement before the turbine and related BPV functions, ensuring stable engine operation without triggering fault codes.

We offer two options: you can order our remote service, where a specialist will configure everything via a secure connection, or you can purchase TruckTools software to manage these settings independently across your fleet.
No physical modifications to the turbo or piping are needed — all changes are made safely through ECU programming.

Disabling BPV pressure monitoring is especially useful for tuning, improving reliability under heavy-duty conditions, or when other systems have been removed or altered. It allows full functionality of the truck while avoiding unnecessary restrictions and maintaining high performance without risking engine health.
