Not sure if my 2015 Fabia III has automatic wipers.   There are four wiper leaver positions, off, intermittent, speed 1, speed 2 and push down for single wipe. In car set-up there is not an automatic wiper on off option in wiper and mirrors set up as  manual suggests.  In the off position on some occassions wipers start and continue and the again sometimes they don't, so is this automatic wipers activating or a fault.

 

So my question is where is rain sensor located on a markiii to service or replace.   Also can the automatic function be de-activated by Skoda dealer as can live without.  Would be really grateful for any insight here.

No. You haven't got auto wipers. 

Thank you Plantese, if non automatic am wonderinng why wipers starting in off position. .I replace the steering stalk

I had this problem you describe, my wipers started coming on even though they were in off position.

I followed the advice in this video and its now fixed,  My car is the same age as yours so likely age related.

To fix is easier than you think the video is very detailed and easy to follow.

IMPORTANT - make sure disconnect from battery and only reconnect when all back together otherwise airbag warning light will be activated.

I'd advise marking position of steering wheel before removing too with a marker pen to be doubly sure you get it in line when fixing it back on.

 

 

I had a similar problem, 2015 Fabia estate.  The wipers were on intermittent even when set to off, so I couldn't turn them off.

I read some of the comments on the youtube video and managed to fix it without needing to do the entire steering-wheel-off thing.

I didn't bother disconnecting the battery but it wouldn't matter if you did. You have to turn the wheel so I left it on.

 

Suggest you watch the above video anyway for background, then see below:

 

Remove the casing round the steering column (one bolt underneath, two on the end facing you, turn the wheel 90deg to access these). The bottom half comes off, the top half remains attached by a flap of trim cloth.

 

Remove the rubbery trim from round the ignition key hole, and carefully remove the little trim thingy from the base of the stalk - the tang nearest you can be pulled very gently toward you with the end of a little flatblade screwdriver, then the trim comes off.  Its very fragile so watch out.

 

Remove the connector from the back of the wiper stalk (he shows how in the video). Until you plug it back in, I suggest you don't turn the ignition on in case it logs a fault.

 

Now, if you look carefully you will see a little vertical slot in the side surface of the casing that the stalk mounts into, near where the connector is located. If you peer in you can see the glint of the contacts in the back of the stalk base. It looks like this slot is there so you can clean the contacts without taking it all to bits.

 

I do NOT suggest you poke anything into the slot - all you need to do is use some contact cleaner spray and squirt it into the slot using the tube on the aerosol. In the pic attached I am pointing at the slot with a screwdriver, but repeat - do not poke anything into the slot. Or if you do, don't blame me if you break something.

 

Give it a good blast with contact cleaner, and wiggle the stalk, repeat until convinced. I also shot some cleaner in around the base of the stalk. 

 

You could probably use WD 40 if you really can't get some contact cleaner, but it is readily available and very useful for, well, cleaning contacts.

 

Plug the connector back in, and test it. For me, that fixed it

Interesting read.  I did find when mine went wrong another youtube video saying to spray it in a different hole but when I tried that it only fixed it for a while before the fault reappeared.  But the hole you have used I think will have better access.  Issue with not taking apart is you can't grease the contacts after cleaning, though I did read some people chose not to grease them even after taking it apart.  I greased mine and not wanting to tempt fate it has been 100% since.  It was easier than I expected to take apart, issue I had was I reconnected my battery before putting it all back together to test things and that threw an airbag warning light which needed vcds to clear.

Using the video posted earlier in this thread I done the 'full' job and as a non-mechanical person put up a sort of guide and tips from my experience of doing so on my wife's 2015 Fabia Mk3 SE hatch. -

 

 

Regarding the lubrication point, you can get spray contact lube (like Ambersil AGL1) which could perhaps be shot in via the same hole - alternatively some contact cleaners are "contact cleaner and lubricant" so they are designed for exactly this - I guess the sovent cleans the crap off then evaporates leaving the grease behind. Typically used for complex switches that can't be disassembled. If I'd had any I would have used that, but I just had the contact cleaner. 

 

A good reason not to take the wheel off is that IIRC the bolt only has a few lives before you're supposed to replace it. I had to take mine off to replace the clock spring previously so one life is already used.

The example I used (instead of re-greasing). - Servisol Super 10 Switch Cleaning Lubricant

I've no idea if that's so, or not, might even be that VW say a new bolt/screw is used each time, I just went with cleaning and thread lock.  Hopefully in an accident the airbag would go off before the wheel comes off but I don't know always better to be safe than sorry or do what settles your mind.
