Good day, I have a problem with my bmw.. It’s a 650i e63. VSD, water pipe and various seals and parts have already been made. Today when I wanted to take it out he smokes extremely (white), so water, starts harder and the idle is uneven. Engine control people is also on and he loses cooling water, however, does not drip, but obviously burns it. I still hang a video in idle. I would look forward to your diagnoses at first glance. what on the cylinder head .. Sincerely Tom
