Another good question. May be you can try to find out if any HTP was issued for such a DAF or Volvo before. The list is not secret, offered as free consultation by the FIA. If you're interested in, what you're looking for is under pdf format, FIA valid-htp-list
I can't remember how I managed to get it, may be Tel can help again. Please?
Thanks for not mentioning "my" English!
Might be this one
