(This post bases on: lstaddons: Dynamic linewidth calculation)
Hey everyone, is there a way to do this with a multiplication instead of two additions?
\dimexpr\linewidth+\lst@linebgrdsep+\lst@linebgrdsep\relax
Thank you in advance :)

If \lst@linebgrdsep is a register then:
\dimexpr\linewidth + 2\lst@linebgrdsep \relax
Hint: Real numbers are also possible.
Otherwise:
\dimexpr\linewidth + (\lst@linebgrdsep)*2 \relax
Note, the first factor is the length value, the integer factors follows afterwards in the product. This is limited to integer numbers.
Real numbers can be supported by wrapping the macro \lst@linebgrdsep in \dimexpr.
\dimexpr\linewidth + 1.5\dimexpr\lst@linebgrdsep\relax \relax

I don't know the definition of \lst@linebgrdsep, so I define it here.
\newdimen\lst@linebgrdsep
\[email protected]\textwidth
\edef\x{\the\dimexpr\linewidth+\lst@linebgrdsep*2\relax}
\show\x
