Regeneration problem on Volvo L180H : FAP Colmaté D13J

Regeneration problem on Volvo L180H : Complete solution

Introduction

The regeneration problem on Volvo L180H is a common challenge for many operators. This type of machine, equipped with the D13J engine, frequently suffers from impossible regeneration, system failure, loss of power, and clogged DPFS. These faults often lead to a switch to degraded mode, considerably reducing the machine's efficiency and performance.

Initial diagnosis

During our intervention on the Volvo L180H loader, we noticed that the regeneration solution envisaged by the customer was ineffective. The soot level was too high, making regeneration impossible. In addition, the AdBlue system was failing, with the NOx sensors operating intermittently, adding a further layer of complexity to the problem.

Solution provided

To solve these problems, we opted for complete machine programming, including the removal of AdBlue faults and the deactivation of anti-pollution devices. This radical approach enabled the ACM managing the aftertreatment data to be put into OFF, ensuring a lasting and effective solution.

Production process

1. Using the dealership's Vocom tool in developer engineering mode
2. Flashing data and programming the EMS2.3 motor control unit.
3. Integration of new operating values.
4. AdBlue system and DPFS no longer required.
5. Deactivation of EGR gas recirculation.

Results

This solution has restored the machine's full power and torque. By eliminating the constraints associated with gas aftertreatment systems, Volvo's L180H loader now operates at optimum efficiency, without the interruptions caused by inefficient regeneration or faulty NOx sensors.

Conclusion

The regeneration problem on the Volvo L180H can be effectively solved by removing the AdBlue system and deactivating the anti-pollution devices. This intervention not only resolves immediate faults, but also ensures optimum long-term performance for the machine.
