Correction:
When share price was 520 EUR, VW weight in DAX was 16.67%
(VW market cap was 151 billion, but 68 billion value assigned in DAX or 45% of shares out or 131 million shares).
and also 1/6 = 16.67%
so one-sixth of the VW price movement is the contribution it makes to the DAX.
Currently VW +30% and DAX +5.4%. So the DAX is up by about 0.40%, if VW was unchanged

When market cap was 68 billion EUR, weighting was 16.67% and DAX market cap was 411 billion EUR
At share price of 800 euros, market cap is about 232 billion EUR. Assuming (to make calculation easy) no change in other components, DAX market cap is 411 + 232 - 68 = 575 billion EUR
So VW would be about 232 / 575 or 40% of the index.
There are some errors in the above calculations, but they should be close enough (hopefully)
