Habitation test throws up a problem

We have just take our swift escape for the second habitation test.

We were not worried however the test revealed some damp as the rubber had perished on the back window and the wall underneath had some damp.

It was very upsetting as the van is only 2 years old

It is covered by the warranty but we are concerned that once the panel has been replaced it will not look the same.

The van does not look damp and has no smell so we were shocked.

Has anyone had a similar experience and if so what was the outcome.
