“I have an old 330ci which is starting to show its age, I hade a vacuum leak somewhere and after a google found this was a common failure and decided I would rebuild my disa valve regardless of whether that was the issue.
The components in this kit are made from mental as opposed to the factory plastics parts so I can’t see this ever being a problem again. The instructions were very good and I ended using the video instead but it was reasonable easy to do, along with this rebuild and split intake hose which I found in the process the car is back up and running better then I can remember.”
