Disco 1 Electro-pneumatic modulator

Hi all, when I got my Disco the EGR system had been removed, I am now hearing a hissing sound coming from this module (right wing near air filter). It has 3 pipes and 2 are broken off any advice on this as I believe one goes to the brake servo pump?

Thanks
Steve

I suggest you simply remove the remaining vacuum hose and stop the end of the hose with a small bolt/screw of suitable size, the leaking vacuum can and most certainly could effect the power assist if the brake booster, causing a problem for you in emergency stopping. If egr is removed no more need for the actuation vacuum.

Sorry for the late reply, but thank you, I have blocked it now as per advice
