Hi,

I have a diesel car and I would like to know if the parameter that the application shows as the number of warm-ups matches the number of regenerations that are carried out on the DPF

No, Warm-Up parameter does not related to DPF.

An "OBD driving cycle" consists of key-on, a driving mode where a malfunction would be detected if present, and key-off.
A "warm-up cycle" means sufficient vehicle operation such that the coolant temperature has risen by at least 22 K from engine starting and reaches a minimum temperature of 343 K (70 °C).

Other words that is engine start operation followed by more or less long running engine operation.

Thanks for the clarification and quick response.

Is there any application parameter that I can consult to know how many DPF regenerations are performed?
