Have read 2 similar articles earlier today stating that due to WLTP the Golf R power is being reigned in a little to comply with emissions.

http://www.evo.co.uk/volkswagen/golf/21458/volkswagen-golf-r-power-reduced-due-to-new-wltp-regs
one article implied that there are dockside workshops making amendments to already manufactured vehicles, potentially causing hold ups across the VAG group.
Probably, given how close they are in DNA, that the S3 gets a similar fix in the not too distant future.
