Hi all, I traded in my 2004 fabia VRS for a 2011 Octavia L&K.

So far I am really loving it, it is such a different drive to the VRS. I kind of miss the low end torque but the turbo petrol engine is a joy to drive and it is so much more comfortable. Also I can comfortably drive it, which is a novelty at 6ft 6. I used to find any longer than an hour in the vrs would start to hurt my back and knees.

I have a rear wiper jet issue that is common, however it is not the usual culprits, I have checked the joint behind the CD changer location which is fine, also removed the boot trim, which is a pain, the pipework looked to be intact too.

I did a little squirt of the rear jet and found a load of washer fluid pour out the boot lid, turns out that the pipe is snapped in the rubber trim that goes from the car body to the boot lid. There is no join there, but the pipe is split in two.

I figured that I could buy a joining coupler, but I need to know the inner diameter of the pipe but I don't have a way to measure it. Just wondered if someone would be able to give me the ID measurements of the pipe, or advise of an alternative fix short of replacing the entire pipe, which I quite frankly don't want to do.

Cheers in advance.

I have exactly the same issue! Usual disconnection culprits all checked and all ok. Jet blown through and totally cleared. Suspect the break is at, or close to, where the rubber corrugated sleeve/gaitor (LHS of the estate door) is that houses electrical connectors and the rear wiper delivery tube...I can see the water dribbling around gaitor. It pours out the bottom of the estate door (when door is closed). Think we have exactly the same problem!

 

I’ve  checked on Skoda-parts.com. There is a Hose repair kit. It gives diameters. It’s a set of shrink fit sleeves:

Nearly  30 Euros though! Shut the Front Door! That’s just a bonkers price!!

On my wife's Hyundai with the same problem, by eye I roughly estimated the inside and outside diameter of the water hose then went to a local hobby shop and bought some thin walled brass tubing and a selection pack of heat-shrink sleeving.

I slid the heat-shrink tubing over the hose, then used a short length of tight fitting brass tubing into the two broken ends of hose. I tested it for leaks like this then shrunk the sleeving into place. Only point to note is that the new fix has to be quite short if it is in a place where the pipe needs to bend on opening/closing the boot.

A garden centre should have a  tubing and joint kit for small diameter tubing . Greenhouse micro watering systems is what I used

Good shout erindad. Hadn’t thought of that. What method did you use to extract the old and put in the new? 
 

I was thinking a bit of string strapped down VERY well to the jet spray end and just pull old tube out and hope it doesn’t tangle/ come away. Then reverse procedure with new tube. OR, I was thinking that I might just tape up (with Gorilla Tape) if Hope was obvious....
