Ash load in DPF

Hello,

I would like to ask for your help. I have two different engine. DFGA and CXXB. 2.0 liter with adblue and 1.6 liter without adblue. The oil ash mass quantity is:

• DFGA - 60g

• CXXB - 11g

The ash mass limit is 80g.

Both cars have the same mileage and are used in the same way. Why is there such a big difference between the two numbers? Is 60g a lot? How effective is DPF cleaning? I'm not talking about regeneration.

Thank you!
