Temsa Maraton EAS4 AdBlue SCR+DPF Removal Emulator Euro 6.2
A single combined plug-in emulator for the Temsa Maraton EAS4 that permanently resolves Euro 6.2 SCR and DPF faults simultaneously, ending the 20 km/h speed cap and torque derate.
The Temsa Maraton running on the EAS4 platform manages both SCR (AdBlue/DEF) and DPF systems simultaneously under the demanding Euro 6.2 emissions framework. This integrated architecture means a fault in either sub-system can cascade: when the EAS4 ECU detects a problem — whether from the AdBlue pump, a NOx sensor, or a blocked DPF with a differential pressure fault — it immediately enforces a 20 km/h speed cap, triggers red and amber warning lamps, and drops the coach into limp mode. The Temsa Maraton EAS4 AdBlue SCR + DPF Removal Emulator is a single plug-in device that simultaneously simulates both emission systems, feeding the EAS4 ECU uninterrupted normal-operation data and permanently eliminating every restriction.
How Does It Work?
The emulator connects to the Temsa Maraton EAS4 ECU via the original OEM sockets using a straightforward plug-and-play procedure — no wire cutting, soldering, or ECU software intervention is needed at any stage. The device simultaneously simulates the AdBlue SCR dosing circuit signals and the DPF differential pressure and temperature sensor outputs. The EAS4 engine management unit processes these as genuine component readings, generates no fault codes, and keeps the coach operating at full capacity.
Frequently Asked Questions
Can the EAS4 emulator be used interchangeably with an EAS3 unit?
No. EAS4 and EAS3 are distinct ECU platforms with different signal architectures; a dedicated emulator is required for each. Please share your vehicle details to ensure the correct unit is supplied.
On the Euro 6.2 platform, is it necessary to cancel both DPF and AdBlue, or is AdBlue alone sufficient?
On the Temsa Maraton EAS4 Euro 6.2 platform, SCR and DPF faults are often interdependent. The combined emulator simulates both systems simultaneously, covering compound fault scenarios that a single-system device cannot resolve — which is why the combined solution is recommended.
