With my 320i it was a crack in the cylinder head. When the engine was warm and running water was sucked into the inlet channel from the coolant channels. There was no visible sign from outside, the engine ran fine, and all pressure tests were fine. Just the water kept disappearing. It eventually failed the emission test so we opened up the engine and found one very clean cyclinder that had been steamed cleaned for the last six months.
Darkness gone, Tronic gone, Solo gone, go Darkness, go Frozen ! What's my F11 called ?
