The emissions fix has ruined my 2014 Volkswagen Tiguan - where do I turn?

I purchased a Volkswagen Tiguan 2.0 diesel from new in May 2014. In October 2016 Volkswagen did the emissions update. Immediately, I noticed these issues: loss of mpg, DPF regenerating once per week, acceleration from low revs is not as good as before. The EGR failed a couple of months after the update and the change down gear symbol on the instrument panel rarely comes on any more. The value of my car on trade-in is only half of what I paid for it, and it's not 3 years old yet. Both Volkswagen UK and the dealer refuse to tell me exactly what parameters they have changed in my cars control unit. It's not easy to prove that these issues are a result of the update and even if I was to go to court, it will be difficult to prove what the car was like before the update. This is my pride and joy, and I feel that this 'fix' is wrecking my engine. I honestly don't know where to turn. I'm a member of the Volkswagen emissions forum and I see more and more cases identical to mine.
