So I have found the following ...
https://www.volvopartswebstore.com/products/Volvo/Protective-plate--beneath-the-engine/9955880/31373040.html
It says that the OE plate will not work with the Diesel engines. Not sure what the issue is here. Anyone can comment on this? there seems to be no bushings on the kit so not sure what that would do to the vibrations through out the car ...
I will call the dealer tomorrow see if I can get one. Ill report on costs and see if its worth it... IPDUSA told me to contact someone to make me one. They do make one for the XC70 not the XC90.
Hunt goes on...
