Hi guys, I have a pre-face 2.2dti SRi and recently posted a thread showing my new silicone vacuum/boost pipes and one of the guys asked what this little black box was as they dont have it in their car. Admitily he has a 2.0dti but as far as I know the 2.0 and 2.2dti engines are near identical. Its part of the vacuum system but really dont know what it is.
Any ideas chaps??
