Volkswagen CC engine rattles since emissions 'fix'

My 2012 Volkswagen CC went back to the dealer for its emissions work back in July 2016; however, since then the engine has developed a very large rattle and no longer gets better than 47mpg (used to be at least 49). I am now worried the engine is going to be seriously damaged. Any advice what I should be doing please?

That is precisely the same problem that has been occurring with Tiguan TDIs (probably because they were recalled first). If the first reprogramming does not work they try another one that may or may not work. See: www.honestjohn.co.uk/carbycar/volkswagen/tiguan-20.../
