Ok 1.4 tdci, bought a couple of months ago. Driving along, and the light pops on with a warning there's engine issues. Power drops, and the thing won't Rev over 2500 RPM. Suspect the previous owners been a tinkered without the knowledge to do jobs properly. 

Quick scan retrieved the usual multiple spurious fault codes, cleared and left me with P0406 egr valve high input, that wouldn't clear. 

Decided to have a delve after work, airbox and pipes off, fuel filter off, which left me with something I really didn't expect.

Most of the EGR systems been blanked and is now missing, and curiously there's a vacuum operated EGR fitted, with an open end that should I now know go through the egr cooler into the back of the engine on the drivers side. There's however no signs of a vacuum pipe in the area, just a straight run from pump to brake servo. This at least explains the egr faults cropping up. I think what's been attempted is blanking off the EGR system by removing everything, which is I believe supposed to be accompanied by deletion in the ECU, so everything works ok.

Quick look on eBay reveals the pipes and bits aren't cheap new, but second hand I can get the major bits for £30. Easy enough to replace. 

However I've a few questions...

1- is the 2008 tdci EGR valve vaccum operated or should it be electric as I suspect?

2- If it's electric, what does the plug for the egr look like? I found a 5 pin yellow (see pic) one loose that I'm not sure about but could be the beast in question. 

3- The egr cooler, is it filled with coolant? Where do the pipes go too/from? Or is it cooled in some other way? In the vicinity of the coolers location is a hose coming forward from the bulkhead and into a pair of pipes that run side to side, it would make sense that this is one end of the cooler, and maybe a short pipe attached from the other end of the cooler would then go where the hose is currently connected. (Hope this makes sense) pic also included

4- The opposite end of the pipe run I think it goes on the top back right side of the engine, theres a ropey looking blank that could well be where it should go (pic attached)

The goal here is to get rid of the drop in power when the ECU spits it's dummy, and get the car driveable, it's a reasonable ride when it's playing fair. 

Thanks in advance to anyone who can help. 

Hi

  top photo the part with the sicker, is the egr cooler (same as mine)

have a look here (https://ford.7zap.com/en/car/54/no/13/1549/15357/66677/)

The EGR is electric not vacuum as on pre face lift models

and your right about that loose plug

    ciao

Thanks for the help with the egr type

Top photo was a screen grab from YouTube so I could try and see what's supposed to be there, and illustrate what was being discussed. It's the best shot I could get, so I could identify he correct location and layout of the hose runs. Unfortunately the lunatic making the video didn't understand about keeping cameras still so it's not a great picture.

The other picture of the vacuum egr  with an open end, and the blanking plug is what's fitted on my car.

If the half wit that did this had just spent £3 on an egr blank, he'd have found it more reliable as a car, if he really wanted to do that. 

I've already used that page linked to identify what was needed, but the hose that's shown, doesn't show where it goes to. Presuming there's supposed to be coolant in the egr cooler that leaves the other end open

Hi again,

             have a look at this may give you a better idea,

  ciao
