Hi
open file "/html/com_virtuemart/productdetails/default.php" in template "ja_autoshop".
Find this code
<li><a href="#review" data-toggle="tab">Reviews</a></li>
replace it with
<li><a href="#review" data-toggle="tab"><?php echo JText::_('COM_VIRTUEMART_REVIEWS') ?></a></li>
Now it will pick the review translation from /language/en-GB/en-GB.com_virtuemart.ini
and if you have other language already it will use it from there.
I already applied the changes on your site, you can check and confirm.
Regards
