And so the strange saga continues...

Picked up a hire car on Saturday - brand new vehicle, never driven by anyone before, so at least there's that.

Born has been left standing outside since the last attempt to recover it on Friday. My other half went to the car today to get my son's car seat out the car and lo and behold, everything is working fine! He took the car for short drive and everything seems to be absolutely fine. Most bizarre.

So now we've cancelled the recovery and will return the hire car when it's convenient for us. As much as I'm tempted to send it back to Cupra anyway to be looked at, I very much suspect they would try to charge us for recovery and then to run diagnostics if they can't find anything wrong with it. On the plus side, it's now on their list for recall once they have a technician available to look at the battery recall fault.

Interestingly, there was a car stolen a couple of roads up from us just a few weeks ago, also a VW Group car, where the key was cloned for the thieves to be able to steal it.

Yet another update on this strange phenomenon... after working fine for nearly 2 weeks the issue reared its head again on Sunday afternoon... so, another call to Cupra Assist. They sent out a technician and they couldn't get it to work. First recovery vehicle came on Monday morning and couldn't get it onto the truck so said they would order a Easy Track. Second truck turns up a couple of hours later, no Easy Track, but key suddenly working again, albeit that a lot of other random error messages came up when he started the car! He took the car anyway because that is what he was instructed to do.

It's now been at Cupra since Monday afternoon and I've not heard a thing from them about it. I did get a bit annoyed with the receptionist in the service department, who tried to claim that they thought it could be an issue because the fob batteries weren't official Seat batteries... hell no! They were changed with Varta batteries and the Cupra Assist technician checked them and changed them again when they attended on Sunday, all fine. Each time, the error message is that something in the system is corrupt.

In the meantime, I'm in a petrol hire car... let's hope they can get to the bottom of the issue because there is clearly something going wrong.

Kinda similar issue here than happened this weekend on a 2022 V1 Born.

I've had a similar situation a couple of months ago when I entered the car and the "Key not detected" error popped up. At that time I just needed to exit the car, lock it, unlock it, and everything got back by itself.

But this weekend was different...

I headed to the car and opened it like I typically do (using the key and not using the door handle sensor). The car opened like normally does and then the same "Key not detected" error popped up again. But this time when I tried the same approach of exiting the car...I couldn't lock the car like I previously did on the first situation. Because *the key simply died*. Not a single button works.

I could only lock the car using the emergency key. The only way I had to get the car back working was by using the second key.

Also, and although no warning message about low battery on the key fob, I've also tried to replace the battery, but no good either. Apparently I was able to open the car and then the key was done for good. Dead.

I have a scheduled visit to my dealership next week for a full car/key diagnostic. I'll get back with news to you just for future reference.

It happened to me too. Locked the car and waited 3 mins and then it worked.

Well regarding my situation described above...I don't have much to say unfortunately.

My dealership ran a few diagnostics on the car and key fob to reach the conclusion that the key is simply dead and it's unrepairable. They'll send me one brand new soon.
