Volvo L120 technical data

Each row states where the data comes from. “Manufacturer data” is the factory figure published by the manufacturer; figures after a remap are shown only where we have our own measurements and records. Estimated figures are not guaranteed results.

ECU and compatibility for the Volvo L120

Services with a verified solution for Volvo in our library: Stage 1 Remap and AdBlue / SCR Delete. The control units we work on in Volvo machines include DENSO 112500-1XXX, DENSO 275700-1201/3410/3411/3412, CONTINENTAL VDO ACM and CONTINENTAL SIEMENS-VDO ATK-EM-EU6. The same model can carry a different ECU depending on build year and engine option, so we confirm compatibility for the Volvo L120 from a photo of the ECU label or from the file read out.

Frequently asked questions

Which software services are available for the Volvo L120?
Services with a verified solution for Volvo in our library: Stage 1 Remap and AdBlue / SCR Delete. We confirm on the file which of them apply to the ECU fitted to your Volvo L120.
How do I find out which ECU my Volvo L120 has?
The exact type is read from the label on the ECU or with a diagnostic tool. A photo of the label and the model year of the machine are enough.
How long does the job take, and can it be done on site?
Most ECUs are read and written through the diagnostic socket and the job is completed the same day; some units are removed and worked on the bench. Contact us for on-site service.
Can the original software be restored?
Yes. The original software is archived and the Volvo L120 can be returned to its factory setting on request.
Why does the machine cut power when there is an AdBlue fault?
When the emission system detects a fault, the ECU first gives a warning; if the fault is not fixed it limits torque and engine speed in stages, and at the final stage the machine runs at idle only. This is how the system is designed to behave. Power returns once the cause is fixed or a software solution matching the ECU type is applied.
Why does DPF regeneration not complete in the field or on site?
Regeneration needs the exhaust temperature to stay high for a while; low load, idling and short work cycles do not provide that. Faults in the differential pressure sensor, the EGR or the injectors also stop regeneration. The soot load and sensor values are read first; depending on the cause we recommend a forced regeneration, cleaning or a software solution.
Does the EGR job give the machine more power?
The EGR job is not a power remap; no power gain should be expected from it alone. Because the loss of pull and the power reduction caused by a faulty EGR disappear, the machine returns to its factory output. If more power is wanted, a power remap is applied separately.
