Thats a loaded question. I would have said no, as mine seem fine, but one of my high pressure oil cooler lines let go on my 535 at 150,000km. You'll have to assess when you're in there. These things have so many "while you're in there" kind of parts, once you start, it doesn't stop. I try to keep a close eye/ear on the car and replace a little bit at a time to keep ahead of it
