You could stand there and blast the f**k out of it with a jetwash and nothing would happen, I have seen it done thousands of times at work just make sure you cover all the electrical bits up and any open filters you have.
What do you think happens at garages when numptys forget to put oil filters and oil caps back on, they have to get rid of it somehow!
Not that it do it on "clit" though, With the french electrics and all that
, wouldnt fancy unplugging all the sensors and spraying them all with water displacer, a mist once in a whiles all she gets that only happens when i neglect it for a year or so lol
