Hi everyone,

 

I am new around here.  I like to try and do as much maintenance on my own car as possible so no doubt will be popping in for a chat every now and then for some much needed advice!

 

Yesterday I took ownership of a 2007 Octavia 1.6 FSI.  So far I am absolutely loving it and very impressed with the quality of the interior and the overall feel of the car.  However, as you would expect with a 10 year old car, there are a few bits and bobs that I would like to sort out.

 

Firstly, the rear washer jet is not working.  I can hear the pump whiring away but I get nothing squirting out (the fronts are fine).  I then discovered a nice pool of water under the spare wheel and it appear to be coming from around the boot latch.  I am guessing that the hose has probably disconnected from the jet somewhere behind jet.  Any advice regarding this?  Is it likely to have disconnected right behind the jet? How do I get the trim off?

 

Secondly, while clearing out the pool of water under the spare, I noticed a hole (see attached image).

 

Is this supposed to be like this?  The other two similar sized thing to the left and right of the spare wheel holder thread seem similar size and seem to be rubber or something similar.  What are these?

 

Thirdly, the cruise control seems to be problematic.  Originally I couldn't get it to work at all, I then turned the ignition off/on and it worked for a bit, but after applying the break (which turns it off).  I have read that a switch can be the cause and it may just need a clean.  However, I have seen mentions of the problematic switch being on the steering wheel stalk and/or something to do with the brake pedal.  Any advice on the most likely cause of this would be appreciated (and pointers on how to fix it!).

 

Thanks all, I look forward to speaking with you all over the coming months/years.

Looks like previous removed the bung to drain the screen wash swilling about there. 

 

I think the tailgate trim is easy to remove. Just remove screws, sometimes hidden under pop out plastic caps. 

 

The cruise is cancelled by the lightest touch of the brake or clutch pedals. I would check the pedals are coming up fully maybe a squirt of lubricant on the linkages before messing about with switches.

 

 

You can get a bung from your local TPS cheaper than Skoda. Or compare their prices. My wife's got the rear washer not working syndrome too. 

I wouldn't be surprised if there is a generic blanking grommet that will fit at a motor factor. Measure diameter and get something slightly larger.

 

Cruise switch is a common problem. If the contact in the stalk is questionable, after cancellation it may refuse to re-engage. As x-man suggested maybe give linkages some lubrication. Check movement of pedal, Maybe clean contacts on brake switch switch assembly. Failing that, clean stalk switch assembly.

Thanks guys.

 

Any idea what the actual name of that bung is?  Struggling to find anything on Google.

 

Regarding the brake switch assembly, where exactly is it and what does it look like?  Is it obvious?  

if you ask for a blanking grommet you should be understood at a motor factor.

In case it helps anyone else, I think I found the part:

Bah! Gaffer tape if you insist. But its actually good to have a drain hole....at least until you fix your leak...

Yeah, thats a good point

 

Got the cruise control module out this morning (much easier than I was expecting), just in the process of cleaning it.

 

Will hopefully get time later on to try and remove that tailgate trim and have a look at the washer jet. 

So far the cruise control switch clean up looks like it has done the job!  Time will tell I guess, but I managed to get it work once yesterday, since cleaning it I took it for a 10 minuite drive and was able to activate/deactivate the cruise control without a single issue

 

Now on to the rear washer jet...

 

So I have managed to remove the trim and access the jet.  To my surprise the hose was still attached although there were clear signs that water was escaping from the jet somewhere.  I disconnected the hose and got my wife to try to try the rear jet while I sat in the boot with a bucket (note the jet does not spray if the boot is open!).  She found soaking me hilarious :( but it proved that the pump and everything was working OK so there must be some kind of blockage in the jet itself.

 

I connected the hose back up and then removed the cover off the bottom of the wiper arm which covers the jet.  The little nodule thing which contains the two nozzels just pulled off and I could see that it was pretty gunked up (I couldn't even stick a pin down the holes).  I sprayed again (without the nodule) and got a nice straight line of water.

 

However, the mechanism of the jet is still dripping a fair bit.  The dripping does not seem to be coming from the hose, it is coming from the back of the black circular bit where the hose connects.  You should be able to see the drips in the attached pic (with the hose disconnected).

 

I am guessing that the blocked up nodule has busted a seal or something inside the jet/motor.  Can anyone advise if this is something that can be fixed or will I need to replace a part?  If I need to replace, can I just replace that specific part or do I need to replace the whole washer jet thing.

 

Thanks in advance!

Using poor / non genuine screen wash blocks the rear jet which if not replaced causes a rust build up in the motor. You can remove the jet & working the washer try & force the blockage out. However a new motor is the option I have found to be best. Then always use genuine screen wash.

Thanks buddy, I think I will just get a new motor for peice of mind.  Can you point me towards the correct part?  I'm struggling to work out exactly which part I need.

 

Thanks

Errm, that photo is the wiper motor, through which the wiper jet is connected. I would imagine a new wiper motor won't be cheap.

 

I vaguely remember there was a thread somewhere showing how such a leak can or cant be fixed. Might be wrong though.

 

This is one

Thanks, it looks like if I shop around I should be able to get a new motor for around £40 I I'm lucky
