Hi just after some help on fitting my egr delete pipe to my pd170 fr leon. Its the bmn 170 engine and im confused to what happens to a small black box attatchement that attaches to the left hand side of it with a grey connecting plug in it. Have found a guide on doing it but the guide is for bkd engine has a vaccum hose going into egr but no black box or plug like mine. Does this just get made redundant and blank off the plug somehow? Uploaded some pics
