Problem Ponsse Buffalo: Permanent defects, torque reduction
Are you experiencing an Adblue problem on your Ponsse Buffalo? Do the particle filter and Adblue system frequently fail and you no longer have enough power to work under proper conditions? We have definitive solutions, especially if you want to export your vehicle or work abroad in countries where there's no Adblue.
Ponsse Buffalo adblue defects
The 2015 Ponsse Buffalo vehicles in our case are equipped with Mercedes OM936 engines meeting Tier 4F standards. These are 7.7L displacement engines developing 280HP. When the ACM (AfterTreatment Control Module) system malfunctions, a number of errors are transmitted to the engine ECU, causing the machine to go into degraded mode, lowering engine torque over time.
The various components that can be blamed for this malfunction are generally the adblue pump, the injector, the adblue gauge, the catalytic converter, the NOx sensors or the wiring harness, which can also cause the system to malfunction. The SCR catalytic converter is often crystallized by the solidification of urea, becoming rock-hard and clogging the system. The cost of an SCR catalyser is around €7,000.
Troubleshooting solution for SCR / DEF system on Ponsse Buffalo
Ponsse Buffalo adblue problems can be solved by emulating the complete system. By sending the correct adblue information via CAN signals, the vehicle is able to operate at full power, and is no longer affected by engine downgrades. The amount of adblue is virtualized, along with all other information relating to the correct operation of the ACM system. Torque restriction, which in our case was 75%, has now returned to 100%, i.e. optimal operation.
As you can see from the picture above, the SCR problem in the Mercedes engine has been eliminated once and for all. There's no need to delete the fault codes present in the MR (engine control) or ACM system. The virtualization module sends the correct data, which corrects the faulty values with the expected ones.
Virtualization of adblue data is achieved directly by emulating data via CAN signal transmission on the ACM/MR BUS. (See below), search for wires for CAN emulation.
