If the original paper is in English but uses the German convention for decimals, and you are going to hold to that convention in the quoted material, I would put a footnote by the first use to explain you are doing so, then simply quote as is. Alternatively, if the dissertation is for an English audience and you feel uncomfortable using the German numerical conventions, convert them and footnote the first usage explaining _that_ to your audience. Either way you've covered the bases. You could also preface your first quote with the explanation, or explain your decision in a foreword. One explanation is enough, however. The quotations will get tedious if you call out each usage. Whatever you do, it would be a good idea to run the idea by your advisor.
