What are the two long aluminium pipes across 1.4TDI engine - above three glow plugs

Hi
Here is a daft question
There are two long aluminium pipes across the engine
Above the three glow plugs on the 1.4TDI
can anyone tell me where the
Top left hand side comes from or goes to ?
Bottom left hand side comes from or goes to ?

Top right hand side comes from or goes to ?
Bottom right hand side comes from or goes to ?

And what do they contain - coolant or diesel ?
Also where are the inlet and outlet pipes for the heater matrix ?
Kind Regards

I think the 2 chrome pipes, not alloy are the oil feed and return to the turbo, the heater matrix hoses are easilly found on the end of the engine just above the gearbox youl find a black plastic water pipe that splits the flow up , follow the pipe... 1 1/4 , 35mm diameter that runs out towards the back of the engine and then goes through the fire wall into the car behind the engine, the one next to this one on the firewall is the return

youl need to post some photos with markers ect to get a reply on the other pipes or infact all the needed answers you require

David youl need photos with markers as to brets reply , as i thought the fuel pipes where right on the top of the engine attached to the front of the head , so without photos youl not get 100% correct answers , if you take some photos , copy them to your pc then right click on a photo and select edit you can add markers or numbers ect and then save and upload the pics to your thread

Hi Gary
Thanks for kind reply
Yes those two fuel metal fuel pipes - where does the fuel go to in those two pipes on the left hand side of engine ?
Do you know the circuit - ie back to the fuel pump on right
What is the function of these two pipes ?
Sorry for being amatuerish

There flow and returns id imagine, as the fuel pump keeps up the fuel presure and some fuel is returned to the tank via the diesel heater under the drivers floor pan ,

well youv got to start somewhere and asking questions must help with learning how your A2 works, When it comes to the A2 im learning new stuff all the time myself, and alot of the time its hands on but a great deal of knowledge comes from this forum and its members

David,

The item under the car is a cooler for the fuel due to the extremely high pressures that the PD engines require.

Keith.
