Hey there 
I'm doing SEO on a bilingual website, passeportvacances.com. The issue we have is that a very important section, the coupons one, is not being indexed by google.
We have a XML sitemap online on Webmaster Tools but it is incomplete. The sitemap generators are not able to get links from the coupon section as they consider them "broken links". Here is the jpg report of the links that are considered broken by the tool.

1) Does someone have an intuition as of why this section is the only one that screws up?
2) What if I add the URLs manually to the sitemap before submitting it, will it work anyways or Google will still consider the links are broken? If so, will it be bad for the SEO?
Thanks a lot for your strategic input!
