No evidence of the damage on mine, it's super low mileage too. I'm happy I've caught it ahead of any problem. It uses no oil and never has. I've changed the oil more frequently than VW suggest as well. The damage only occurs if the cooler breaks down and stuffs aluminium into the bores.
I have to ask, you've spent a lot of money on a new EGR cooler knowing that you'll have to rebuild/replace the engine soon enough, why didn't you just blank and emulate the egr? Would have saved you a grand towards a new block.
