Very common its part of the evap system to recirculate fuel vapours from the tank to the engine. Fitted loads. Full pipe usually comes with the purge canister valve and resonator etc. if you look at the resonator that clips into the coolant tank then there should be a part number you can use.

So when you say you have fitted loads, is it common the quite rigid ribbed hose splits often? 

Yeah they always go in pretty much the same place. Sometimes can sound like a knocking noise. You could try putting some quality tape around it if it isn't split right at the end.

Already wrapped with amalgamating tape as a temp measure. Seems a daft place to put a nearly rigid pipe that needs to flex between stationary wall fixing and flexing engine. Hmm. Cheers for the help

It is possible that someone has damaged it when working on the vehicle as they are very brittle plastic.

That solves that mystery Temple2019, makes sense that they go the journey all of the time!  Bet they make a fortune using such a brittle material in a position like that.

The old vrs ‘snot machine’ had the same problem with brittle vacuum hoses in silly positions.

 

Told you this was a great forum 😎👍

Blue8793841 i think the problem is that it is mounted against the air intake system and likely wriggled about when servicing etc? Just seems a daft place to put a rigid tube given that other parts are silicone/rubber hoses. 

 

Do you know what issues it would be/could be causing if cracked or fully snapped?

Hello it is the petrol vapour recovery system with activated charcoal, the bottom tubes come from the tank the broken one from the intake manifold, it should not produce many vapours (injectors) but it would be advisable to change it to avoid problems

It is a stupid idea, the higher end cars use rubber hoses, with the rocking of the engine back and forth while driving they are bound to split. Not to mention go brittle over time 

it can be fixed with a piece of good quality fuel hose. you have to remove the plastic corrugated pipe and replace with rubber hose

Hi Temple, did you replace the Evap pipe yourself? Was it as straightforward as it looks?  I've got the same issue but I'm loathe to part with the £250 that Skoda have quoted me.

I've fitted quite a few on both the 1.5 and 1.0 you should be able to do the job yourself, just be careful as they are easy to break.

You know something, I've just bumped into this thread, my wife's July 2015 build, VW Polo with the 1.2TSI version of  that EA211 engine, left the factory with a ribbed plastic pipe fitted to it's equivalent EVAP solenoid, it started to annoy me that I could hear "beep beep beeeeeep etc" under certain engine/car operating conditions - then I spotted a posting saying that VW Group had dumped using that ribbed pipe and were now fitting a pre-shaped smooth bore pipe to sort that noise out.

 

So I annoyed my local VW dealership enough about this and they raised this issue with VW mothership, who pointed them in the direction of the new smooth bored pre-shaped "rubber" replacement pipe and fitted that under warranty, so that stopped that unnecessary noise which was due to that ribbed pipe being sort of tuned to the pulse duration of the EVAP solenoid.

 

I'd think that over the years, VW Group will have got round to replacing that type of pipe for a pre-shaped smooth bore rubber version, on that model of engine - looking under the bonnet of a newer "same" car would reveal if they did or just blundered along with using that cheap crappy ribbed plastic pipe - in that, which looks like a badly designed/cheap layout, that pipe does end up being quite a bit longer than it was in the earlier 1.2TSI EA211 engines - every penny counts, f' the customer, money for old rope a few years down the line and repeat a some more years later?

That subassembly, that has the ribbed hose as part of it, started life as 04C 133 352 BC, later on it's part number changed to 4C0 133 353 AS and much later to it's current part number which is 04C 133 353 BF.

 

It might be of interest to find out what exactly was altered to prompt these two part number changes - as maybe one thing that was changed was this weak/cheap design of ribbed pipe.
