Hello forum,
Since my VW used car warranty is about to expire, I'm thinking about what I can check to avoid looking foolish shortly after it expires.

Furthermore, I'm considering how one might potentially save an extra Euro or two.
So far, I have not made a claim under the warranty because there are no defects (except for a noisy but functional air conditioning compressor

).
However, I heard from an acquaintance who had arranged with another car dealership that they would replace the timing belt.

Since this is known to be expensive, he agreed with the dealership that the water pump would be declared defective.

Then, the VW warranty paid for the water pump replacement... And of course, since the timing belt and all tensioner pulleys must be replaced at the same time when replacing the water pump, those were also covered by the warranty... } (This whole thing happened with an A8 3.3 TDI, but it should work just as well with our 'slightly' smaller version...)
Does anyone have similar ideas on how to get a lot of work done under warranty by exploiting a small defect?
Best regards and thank you in advance for your creativity.
