I need some advice.

My DPF ash amount is reaching its limit according ELSA manual.

Current value is 0.16L and limit is 0.175L of ash:

Car is now on 241000km. There is no any DPF light or warning neither performance change.

Do I need to make any cleaning of DPF or to take it out and give to specialist for cleaning or to add some aditive to fuel tank?

Any advice is appreciated
