You don't really need an opinion on that, you can prove it yourself by going through the procedure of refitting it to see if it replicates the fault. If it does then then you will know it was your action that causes the light. Sounds like it's a very easy thing you can do, even with them as witness, then both parties can be satisfied. What do mean by repairs? What needs repairing?

Honda NSX?

Not an MOT fail.

Could get a bottle of that anti-mist spray to help prevent interior windscreen and side windows misting up.

I have noticed roof rust on my GTI in the same place as an above poster, around the 2 holes where the spoiler is fitted, so it can only be seen if you remove the spoiler. I am wondering if this is actually a common rust area on Lupos but not noticed as much as the gutter rust as people don't remove their spoilers? I think VW should honour the repair as basically its corrosion and not from any fault of the owner, its a build fault from factory. I have not asked VW about it yet or argued my view to them.
