Wooden brakes due to brake assistance being compromised (hell did I just say that). Yes the vacuum pipes to EGR and Turbo come from the Power Brake Booster so if there's a leak in the hose or Controller, brakes will feel harder to stop. I think the controller (three port thingy) at front of engine vents off the vacuum when engine shut down but not a long hiss.

 

Thanks everyone for your input, we have finally sorted the issue...and yes it was the 3 port vacuum thingy!!!!...better known as PART No. K05149105AA an "Electro-valve" brakes all ok...no DTC's...No MIL...No hesitation...Less smoke on acceleration...and even though there is one listed second hand on fleabay for £20 plus P&P....the price from Chrysler Dealers...wait for it.....£25.00 +vat ...Bargain, thanks everyone for your input

 

WoW £25 + Vat...Take a note of that Part No...Is everyone's working ok, no slight Vacuum leak, working at all ??

 

everything is working perfectly, no vacuum leak or hiss after shut off and the simplest of fix, checked all vacuum lines and no leaks evident...the price surprised the parts guy, when I showed him the pic of the part when ordering he immediately made that sucking in air noise, and said "that will be expensive I bet....errr no"...think I might buy more JIC, when you google the part No it comes up as a Fiat part also...go figure LOL
