If you mean the pipe from the intake manifold to vacuum pump, it's one piece.  The check valve part isn't available separately.

The pipe and valve are recent where the pipe goes into the engine theres a plastic pipe fixed what I assume is the crankcase  that has snapped Thanks for your reply I am waiting for dealer to ring back

o.k the plastic part is available common fault the plastic degrades over time causes idle fluctuation and breaks when you remove the pipe which is what has happened I will post again when I get the new part may help someone else

OK no worries.  Well that whole pipe assembly is sold as one piece like this, if it helps.

The bottom pipe in the above picture goes into the the coolant flange part number 06F121132H which acts as a coupler and joins it to the brake servo pipe.

Got new part today took to garage they rang to say it wouldn't fit without a modified clip for one of the pipes off the road till tomorrow. No mention of it when they handed it over. Bloody useless

did you get the plastic plug that fits over that open small bit of plastic pipework? I suspect that's what your garage says is missing.
it's part number is 056 129 777

Hi there,

I was changing my gearbox clutch yesterday and I snapped that damn pipe. I think it must come from the servo then joins into a piece which also has water pipes. Is the vacuum part just a way of connecting both pipes ie can I just re-route with another pipe and by pass this? If not does anyone have the part number for the tree?

Thanks

If it is the the coolant flange just above the gearbox you are talking about, then the bottom pipes just connect 2 pipes for the heater matrix, the 2 pipes above that connect the vacuum pipes together. If you have just snapped off one of the vacuum pipes then you can just connect the 2 together and bypass the flange and all will be good.
