I have fitted the EGR blank to my TD4 and now get a loud sighing noise every time I switch off the engine. I guess it's the pressure in the inlet system
Does anyone else get this
Should it make the noise
If not how do I correct it
Cheers
I got the same after I cleaned my egr valve and blocked the vacuum pipe to prevent it's operation.
It sounded like it was the egr modulator trying to pull on the egr diaphragm.
Since I was retaining the egr valve I decided to follow a tip from TDJohn to block off the exhaust connection with some metal cut from a tin can, then I was able to reconnect the vacuum hose to the diaphragm and the noise stopped.
I'm not sure if removing the modulator or disconnecting it electrically will generate a fault code.
Try disconnecting the egr modulator vacuum pipe from where it tees off from the main vacuum hose between the vacuum pump and brake servo, remembering to plug the tee to prevent loss of vac for the servo!

Did the EGR mod to my 2006 TD4 today. Blanked off the vacuum hose and made sure all the fitting/gaskets were clean and tight. No dash lights or odd noises, seems I was lucky. Certainly the hippo accelerates more cleanly from a standing start now, with tuning chip and MAF compensator fitted too I'm running out of tinkering options...............

thats the one i was searching for.
mine also stopped when the egr vac pipe was refitted. (i blanked the exhaust instead) i think if it's disconnected the other side of the egr modulator/solenoid it may not happen..........'mickb' give it a try...
