When I write "m³", the '³' is missing in the pdf.
So I wanted to try with siunitx, but I get an error when I try to use
that with dinbrief.

Example source file:

\documentclass{dinbrief}
\usepackage{siunitx}

\begin{document}

\begin{letter} {Adresse}

\opening{Sehr geehrte Damen und Herren!}

\closing{Mit freundlichen Grüßen}

\end{letter}
\end{document}

Gives me the following error (tried with both xelatex and pdflatex):

! Undefined control sequence.

I don't see your m² in your document, so it's normal it's missing in the
pdf.

To answer your question, here's a real ECM which do what you want.

Or to get m^3 with dinbrief use the standard LaTeX m$^3$ for m in roman type, $m^3$ for m in italics.

>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
\documentclass{dinbrief}

\begin{document}

\begin{letter} {Adresse}

\opening{Sehr geehrte Damen und Herren!}

m$^3$

\closing{Mit freundlichen Grüßen}

\end{letter}
\end{document}

dinbrief is no longer compatible with a current LaTeX as it
redefines \document and \enddocument in a way that break various
hooks (beside other \AtBeginDocument no longer works).

Use another class.

That was a small example to reproduce the conflict between dinbrief and
siunitx.

For superscripted digits in normal text (ie NOT in mathematics),
use (eg) m\textsuperscript3

lettre (from the Observatoire de Genève) is an alternative, it can be
used to write letters in German.

Koma-Script's scrlttr2 is the de-facto standard these days
