Submarine test

I was very curious: Will my car be waterproof ?

Yes it has survived even being fully under water. There are
a few lessons, that have been learnt:
- there is much more to consider than the electronics
- for example the tires air vents let them fill with water
- I was concentrating on the waterproofness, but forgot,
that the Cayenne is no crawler - let's say the offroad
capabilities have been a bit limited, esp. under water
on the slippery stones
- always bring a towel when playing at the creek
- I'm quite happy, that my camera did not fall into the water
- The car is really still working, but it smells a bit like forest
