Will disconnecting the EGR valve on a Xsara HDi result in the engine management light coming on? I remember quite a few rover diesel owners used to do this to give them slightly better performance.
What do you think? Yeah or neh!?[:)]

as long as you just block off or clamp the vaccum pipe & dont disconnect the electrovalve it wont bring the eml on.i dont really think it will do anything for the performance though to be honest.

wouldnt you get a better burn of fuel though as your not getting any of the 'dirty' exhaust gases recirulated? If not, sod it Ill leave it as it is!

EGR on an HDi is only operational at idle & light throttle,whenever you need power the EGR valve is shut off by the ECU anyway.
