Dear Franziska Weis

You can run the test of serial

correlation (Breusch-Godfrey test) and the test of homogeniaty (Breusch-Pagan-Godfrey test) and if you accept the null hypithesis in both tests you can conclud that you VAR estimation is considered acciable even when the test of normality is fail.

Md Fuad

Dear Franziska,

It's not a serious problem for VAR. You may care about the other two tests (heteroscedasticity and unit modulus) of robustness. If you are a stata user then follow the instruction in "Introduction to Time Series Using Stata" by Sean Becketti.
