Passenger fleets that can't afford a roadside emission problem.
Our AdBlue / DPF delete units disable your bus or coach's AdBlue / SCR / DEF / NOx / DPF system for good. Passenger transport runs on timetables — a coach pulled off the road because the DEF pump failed is lost revenue and a lot of unhappy passengers.
We fit plug-and-play emulator kits directly to the ACM so the aftertreatment system is bypassed cleanly. No strange software, no loss of power, no dashboard warnings.
Built for your duty cycle, not a European catalogue page
Bus and coach duty cycles are particularly hard on SCR and DPF systems — long idles at terminals, frequent short trips that never get the system up to regen temperature, and varying AdBlue quality across fuel stops and depots.
Our bus-coach kits have been fitted to city fleets, long-haul tourist coaches and school-bus operators across NZ and AU. Install time is 45 minutes or less.

Common questions about bus & coach deletes
Will an AdBlue delete affect the bus's emissions certification?
An emissions delete changes the actual emissions output of the vehicle, so it will affect any emissions certification that was based on the factory configuration. This is an important compliance call your operator needs to make — we'll walk you through the implications.
Do you work on city bus fleets or just coaches?
Both. We've done work for long-haul tourist coaches, school bus operators and urban transit buses. Duty cycle matters when we spec the kit — city buses with a lot of idle time are hardest on SCR.
Can we do a trial on one bus before rolling out to the fleet?
Absolutely — we recommend this approach. Do one bus, run it for a month, then decide whether to do the rest of the fleet.
Do you service Chinese-built coaches (Yutong, Kinglong, Higer)?
Yes. Most Chinese coaches use Cummins or Weichai engines with aftertreatment systems we have delete coverage for. Send us the engine family and ECU part number.
