Looks like the Zed is showing the typical signs of this deteriorating. Called Sopers and was informed the valve and pipes had to be ordered seperately and were not available in kit form which surprised me as a lot of threads make reference to the existance of such a kit. Only other supplier seems to be on ebay selling the parts as a kit, So the question is if there is a BMW OEM number for a kit what is it and if not has anyone used the ebay supplied kit at all??
Thanks
