DPF for W463 1999

I'm looking to install a DPF on my G300 TD
The model I have is G 300 3.0 Turbo diesel (463.330, 463.331) (130 KW / 177 HK)
I found this DPF which fit the car, but its not approved by TÜV so it won't be registered in my country (Denmark)

Im curious to hear if any one have tried to install a DPF from another model? or have knowledge about where to find a DPF that would fit with right documents.
