I'll see if I can dig up what I used. I used a brand that claimed to be an OEM supplier. I think it was Cohline. It's been about 45K miles and there have been no leaks.
Mach4 has a solution where he made his own lines. You may want to look that up. I believe his adds an additional failure point, but avoids the hell job of the upper line. If I couldn't find OEM quality, I would do something to his setup.
I would not recommend any solution using regular hoses and clamps. Many of the hoses people used were not rated for the proper temperature, pressure and level of stress required and usually resulted in them being removed from Mercedes diesel ownership.

Look at the Choline hose on your vehicle and see if the number on the Hose matches the picture. The picture is of the 15mm inside diameter Choline hose that Bellmetric sells by the meter and it is the same hose that is on the aftermarket hoses that use Choline.
So the hose issue has been solved. This hose has been on my Car for at least 2 years not with no issues.
I have double Oietiker clamps on the each end of the Oil Cooler side of the Hoses and double Norma Clamps on each of the Oil Filter side of the Oil Cooler Hoses.
I did the Noma Clamps because I could not get in there and crimp the Oietiker clamps, not enough room.
