Can anybody help me please? I have been attempting to remove the heater matrix and to replace on my mk2 2012 1.6tdi. 
 

I am 99% of the way there (done the internal dismantling to remove through footwell etc).
 

However I am flummoxed as to how the pipes come off that attach to the matrix through the bulkhead and don’t want to yank and break them.
 

There are 2 pipe elbows with clips on that go into the plastic inlet/outlet. I am aware I need to get the pipes off to access the single spline bolt to remove the matrix. How do the pipes come off? 

Are you looking at 'quick release couplings' like this?

If so you pull the wire retainer out as far as it goes, then pull, hard probably.

Does not seem to be any special clips, just remove pipes, disassemble interior and remove.....

 

When removing pipes, be careful to not "squash" the pipe oulets with pliers, try to free the hoses by twisting or if access allows get underneath the edge with blunt tool to "break the seal"

 

Workshop prodcedure attatched.

That’s what they look like - the elbows are thick and mean I can’t get to the nut that is displayed on urbanpanzers diagram. I did undo the clip

before and give it a good pull but it didn’t seem to want to go anywhere. I guess I’ll give it another go.

 

thank you to both of you. If anyone has  any experience of i doing them please let me know 👍

If you still struggle, try slight rotations, if the flexible hoses allow, to break the stiction of the o-ring inside, then pull.

The wire clip only needs to come out a short distance to release the elbow, once you've released the clip just wiggle and twist the elbow until it comes off.
