KESSY issue

[xobb1t]

Hey guys, got some strange issue.
After temperature went below 0 Celsius opening with KESSY on my Formentor 2021 sometimes doesn't work.

Locking usually works on both handles, but opening - not. After staying in warm parking it started working again.
May be someone else experience this issue?

It's a known issue, several threads on the topic.

Hey, thanks for answer! So, there is nothing to do (I mean warranty replacement)?

Not that I’ve read, try warming your hand up before trying to unlock the car. Have a search in the forum for some of the threads about the topic.

Get Kessy switched off and use the remote that has been doing the job great for many years. Also your fob battery will last a lot longer too.

I use opening trunk by movement under it sometimes. It's very convenient, so I'm not ready to switch off kessy completely :/

Less chance of someone stealing your car via a relay too

Has your car had the service campaign for the KESSY carried out?

Actually the Cupra key have a nice feature that turns off kessy if there's no movement for some time. Won't help if you carry the key in your pocket and move but if you place it on the shelf in your home it will stop emmiting kessy signal and there would be impossible to steal via relay.

It's a more advanced system than the key just going to sleep. The keys transmit UHF in addition to the usual KESSY signal. We made a post on here explaining the new system with screenshots from the VWAG self study programme however I'm struggling to find it now

You've just given me a fantastic clue into an issue I'm having with the last note in that snippet from the manual. Thank you!

That would be this post, I assume.

Very informative.

You can also turn off KESSY when you lock the car.

Yes, I always follow that process when locking my VW with keyless entry / keyless start. My car is too old to have the key fob with motion detection.

Keyless entry/ keyless start was part of the standard spec on my car; if it had had been an extra cost option I’d never have paid for it.
