Tow bar load weight 2015 Berlingo XTR 120

[David McInnes]

I'm trying to find out the tow bar load weight of the 2015 Berlingo XTR 120 but even after asking Citroen dealers they don't seem to be able to provide.
I belive the weight to be 70Kgs but from taking to a friend in France who has just purchased a C3 with the same 1.6 120 engine the load weight has been reduced to 35Kgs.

Any help or pointer to where I can find the information would be most apreciated.
