A little help identifying a vacuum hose

Top tip: trim off the cracked section, heat up the good section with a heat gun, slide it back onto the fitting. Job done :happy2: The cost of that whole hose from VW is unsurprisingly, very steep!

Are you suggesting I leave the old barbed part in the engine? Access is pretty awful down there, I doubt I could get a heat gun in without taking out the battery and a bunch of other pipe work :sick:.
It's this end that won't pop off, even though it would seemingly be the easiest as it has no visible clips.

Half a can of WD40 with incessant tugging and turning, the plastic and rubber sections parted company allowing me to remove it. The old rubber part came off with a pick and the new pipe section is now on.
What a bloody drama over a simple pipe :grin:

Well, as the old saying goes - if you can't fix it with gaff tape or WD40, you simply haven't used enough.

No you'd need to remove the entire hose to do it properly if access is too tight, but it comes out easily enough. It just saves you having to replace the entire thing which is £££s. You can of course bridge the gap with rubber or silicon hose as above, but my concern is there is a LOT of vacuum put through that pipe, hence it's rigid plastic construction, and when it comes to brakes, you really don't want soft hosing collapsing under the vacuum.
