Temporary fix, while you source a new pipe, use some self almalgating tape stretched tightly over the splits and joints. Doesn't stop the vacuum leaking completely, but safer to run than doing nothing.

 

The non return valve in the middle of the pipe run will probably be shot too. It comes as part of the replacement pipe.

 

My independent specialist sourced one from TPS for my BZG 1.2 engine. Cost £42 iirc and they fitted it for free, took less than 5 minutes, most of that being to find the tub of grease which they lightly smeared on the ends to assist fitting.

 

The independent remarked that with some VAG engines (golfs came up), he found it impossible to source a replacement.

It failed on mine and kept causing the brakes to suddenly snatch on. It was very dangerous and frightening. A new pipe with valve cured it permanently.

Replacing the old hard plastic stuff which was barely attached with £5 worth of 10mm vaccuum hose seems to be an improvement. 

 

Time will tell if it sorts the intermittent problem.
