Volkswagen Emissions Scandal - what happens if they can't fix my car?

I currently own a Skoda Octavia 1.6 TDI (purchased days prior to the news of the cheating) and I've followed the saga with interest over the past months. With the situation regarding the 2.0 engine and no sign of actually being called in for a "fix" I've been wondering what would happen if a suitable fix cannot be found. What could/would the Volkswagen group do?

There is a fix for the EA189 1.6TDI described in this section on the VW Golf VI: But VAG just doesn't seem to have applied it yet. The 1.6TDI also seems to be unusually prone to premature clogging of its EGR valve in as little as 40k miles and owners are being asked up to £1600 (Audi dealer) to replace this.

Latest on the 'fix' for 2.0 TDIs is that it increases the revs at which peak torque is developed by 300rpm and that explains the 'rattling' owners are experiencing when they change up at the engine speeds they were used to changing up. Basically it ruins the drivability of the engines. The EC Court of Justice wants the UK and German Governments to prosecute VAG.
