The long and short of the whole issue is this though...we all know through common sense that car companies (or any manufacturer for that matter) will do their level best to get out of paying for warranty work, whether this seems fair or not. If you change the power output, realistically the only items on the car that they won't try to wriggle out of are a) something not electrical and b) something not related to the car moving.
So yes, it's a kick in the teeth when the manufacturer makes it hard work, and yes it may seem unfair and I feel for ED35chunk. But why are we surprised?! It's one person against the biggest car manufacturer in the world, through a VW franchise. And even if the dealer tells you that there wasn't enough oil in the box, they'll report something different back to VW as they're essentially backstabbing VW for telling you they filled it 'just so everything seems in order'. If he was truly on your side they wouldn't have filled it.
It's your (with the mappers help) job to prove that the map isn't to blame...but how are you going to do that?! These issues are the opposite of our justice system (innocent until proven guilty)
And after what I saw whilst working in my BMW dealer for a few months, you'd stay away from them too...
