diesel oil will now pass through the water system and your engine will go bang....
Must be an FR TDi part as I can recall seeing that on mine.
I still have mine in place. if it comes out in one piece, i'll be taking mine out fairly soon too.
i'm sure seat just put in for show seeing as its so obvious to the eye, i'm all for mods but surely a car manufacturer knows better than 99.9% of us on here. From what others have said it made absolutely no difference so why remove it?
