These services are intended only for motorsport, off-road, export, test or other legally permitted use. The customer is responsible for local law, inspection and insurance consequences.

Why is support file-dependent?

Aftertreatment strategies differ by ECU, software version and hardware state. We check the original file before confirming what can be prepared safely.

What should I mention in the order?

Describe the hardware condition, current faults, sensors, warning lights and intended use. Clear information helps us prepare the right file faster.
