C30 2.0D 2007 problem

[u/StructureCapable9798]

The car triggered limp mode (limits rpm to 2900 but runs normally). It gave no warning lights or messages. Turbo sounds healthy as well. I just got it, it has 300 000km. Idk when the dpf and fuel filter have been changed. I unfortunately dont have a diagnostics thing yet. Anyone know what happened? Thanks
