The kessy system in my '14 Outdoor L&K has stopped working;

• keyless start button and remote lock/unlock -- working fine
• keyless lock & unlock -- not working.

 

The display says "Keyless faulty"

 

I've tried all the usual resets, changed remote batteries but no joy.

 

Brought it to a local auto electrician, he found a fault code P1025 and 1058048 (fuel pressure reg valve) and says the engine fault is disabling the kessy system, he couldn't help any further.  

 

Despite a reset the fault re-appeared after a few days.

 

Whether its a coincidence or not, the fault started very soon after I had a towbar fitted by an independent fitter but the auto electrician checked around the bumper and found everything ok.

 

Any advice?

I recon the fault you mention will be to do with the immobilizer (can anyone confirm that?). Do both keys do the same? It may just be coincidental that your keyless fault appeared after your towbar had been fitted but depending on how heath Robinson the wiring has been done (I assume your indy did the wiring). It may have contributed to your current issue. Was your fitter/towbar company an approved one or a dude in a lock-up? 

Do you have a reverse camera or parking sensors or trailer stability control on your yeti? If so do they all function as they should with a trailer? For example do your rear parking sensors shut off when a trailer is plugged in?

As you say though, it could be nothing to do with the towbar. 

You may have to bite the bullet and go to a Skoda agent or vag specialist to get the codes read properly.

What type of tow-bar and electrics were fitted and the price?

Very unlikely to have a reverse camera at that age.
It will have parking sensors, and stability control, which are both affected by the towing wiring and programming.

As Urrell says, we need to know EXACTLY what wiring has been fitted for the towing electrics, plus whether it has been reprogrammed. I suspect the fault lies there!

Thanks for your replies. 👍

 

The towbar (& interface relay kit) was fitted by an independent towbar/exhaust firm, they also do work for the dealers, job  cost €350.   They didn't reprogram the car - I suspect they aren't setup for that level of work.

 

After the problems with the central locking, I went back to have the wiring removed which they did and left in the boot.  The auto electrician checked it out and said everything was in order i.e. wiring put back as it should.

 

I don't have a camera/stability kit.

 

 

So with your towbar wiring now removed is your keyless fault still present and fault codes you mentioned in the OP?

I suspect that there-in lies your problem.

The by-pass relay kit is not a recommended fitment for the Yeti, (or any VAG model) and to be honest isn't that much cheaper than doing the job properly and using the proper towing loom. I'm sorry to say has been known to cause problems with the car's electronics, sometimes expensively. It also does not integrate with the car's systems such as the stability control system (Yes you do have one), alarm, internal display or rear parking sensors.

I suspect that your only answer is to find another and better tow bar fitting company and get them to fit the proper loom and then get the car reprogrammed.

For your reference the re-coding gives you the following when a trailer is plugged in:
Towing display on the central "radio" unit when reverse selected.
Disables car rear fog lights.
Disables rear parking sensors.

Alters the stability control system to allow for a trailer.
Extends the bulb failure system to the trailer, and therefore gives the legal requirement for a warning if the trailer indicators don't work.
Disconnects the Stop/Start system.
Extends the alarm system so that it triggers if the trailer is unplugged when the alarm is active.
Alters the flash rate of the indicators to allow for the extra lights.

I note you have not stated where you are  located. It would be worth stating that as it is possible that one of us can recommend a proper fitter.

I can't help with the KESSY issue but as a point of reference, you certainly could have a reversing camera on a 2014 L&K Yeti - TIBET III was built in Jan 2014 with one.... 😉  

You do have stability control on your Yeti but with a trailer connected without the car being programmed to extend to that it will probably be fighting against itself making it worse than none at all.

When you say reprogrammed, I presume thats a job for the dealer?    and its more than just clearing the faults?

 

I'm based in Galway, Ireland and unfortunately we are surrounded be general messers and very few proper fitters...actually I don't think there are any.

Yes exactly, and thats after twice clearing all faults.

 

 

Forgot to mention that my spare key is no longer sync'd to the car (battery replaced and tried a few reset methods from here and elsewhere)

 

Finally, I may as well get the dealer to look into the P1028 fault pressure value thingie since that keeps coming back.

Dealers are able to do, obviously, but any person with a laptop and the correct equipment can also do it. Reputable tow bar companies, especially if they fit Westfalia bars and electrics will also have the equipment. 
Yes it is more than just clearing the faults; see the list of things that are altered.

I am sure there are reputable companies that are capable of doing the job properly, but I suspect you are going to have to travel to get it done.

How have they cleared the faults? I suspect they are using cheap generic units!

If your spare key is no longer synced to the car there is something drastically wrong here. That is probably going to need a dealer to sort out.

And please, add Galway to your Location on the left, instead of the computer.

Some good approved towbar specialists can reprogramme, however that doesn't sound like it will be an option for you. So you will likely have to get your Skoda agent to complete the rest of the job for you. By that I mean resetting and if necessary repairing your fault code issues and also fitting the correct towbar loom and reprogramming for you and sorting out your spare key issue. 

^^^^ basically what Llanigraham said above. I was writing a reply at the same time as he.

Thanks folks for your advice, I'll go back to the dealer and take it from there. 👍

Just to update on my situation, it went back to the dealer who found the antenna under the bumper was disconnected and everything is working now..

 

The dealer replaced the battery in the second remote which resolved that issue, even though I replaced the battery at home which didn't resolve the problem.

 

anyhow all is working now!
