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)

Quote from m22au:
Alternative trade idea:
Instead of long Porsche and short VW (which is not working)
a trader can short DAX and then long another European stock index.
This is not an arb but rather a speculative trade based on the idea that if/when VW falls, it will drag the DAX down by a fair bit.
