Jamie330d Posted February 2, 2014 Report Share Posted February 2, 2014 It's the vacuum pipe of your EGR and it's been capped to stop the EGR opening, it goes on the small silver pipe coming off the EGR. Zim 1 Link to comment Share on other sites More sharing options...

bungers Posted February 2, 2014 Report Share Posted February 2, 2014 To stop all the exhaust crap being fed into your car's inlet. It's not a bad thing it's disconnected. Zim 1 Link to comment Share on other sites More sharing options...
Lewis330m Posted February 2, 2014 Report Share Posted February 2, 2014 So exhaust gases dont re circulate back into the combustion chamber. Will also mean less carbon build up in the inlet manifold etc. Zim 1 Link to comment Share on other sites More sharing options...
Lewis330m Posted February 2, 2014 Report Share Posted February 2, 2014 (edited) Yeap, Zim its a good thing, just tuck it back away out of sight....

dooge Posted February 3, 2014 Report Share Posted February 3, 2014 Depends on year, not all years will bring up the emissions light if the EGR is blanked. I removed the EGR and fitted an Allard EGR delete kit. Link to comment Share on other sites More sharing options...
