Quality rubber seal for rear doors on all Mini vans and estates. Old seals will not only cause water and air to leak in, but also can cause a very annoying rattle. This is the left side and is a split seal, see 14A7608 for left side which is a full square.
 
This style seal used clips to fasten it to the door, and they often break upon removal. Together both rear van seals use 57 total 14A6585 clips.
