this is my guess. when I changed the vcg in my x5, most of it was still pliable expect the inner seal around cylinder 5 & 6. there it was quite crispy and it broke apart when removing it.
op. since you are deleted and and I'm assuming the turbo is in good health, the next logical cause would the the vcg. especially at 200km
