Model Year 25/26 2025 Formentor PHEV V3 PV4 update

[BenjaminSurtees]

having multiple issues with my Formentor. I am aware there is a new PV4 update that got released a few weeks ago. (i'm only aware of this due to a friend who has the same car was told about it after issued caused his 12V battery to die and the car had to be towed to a main dealership. Cupra has not told me about this update until I phone a main dealer and asked them directly)



I took it in a few months back to have a software update as was having wrap around lighting flickering and electric drive train stopped working.

now sitting on the below software and having further problems.

Current software : 2768

all previous issues have now been resolved however I'm now having further issues on this updated

Issues:

Travel Assist is currently unavailable

Screen sometimes turns off and unable to turn back on

Front assist is restricted

Lane assist is unavailable

Dynamic Road Sign Assist currently restricted

Light assist: Sensor Impaired

Error: Emergency Assist

All sensors are cleaned prior to departure. Some assist systems will come back online after driving for a prolonged period of time bar the Travel assist - that is perm unavailable.

my question is will this update fix these issues? i'm getting rather fed up of having to travel back and forward to a dealership then being asked to pay for a rental car while the car is in for a couple days.

To be honest I'm also fed up with the awful customer service.

 

[James_R]

The 90Z1 recall was released recently, but that's just a forced implementation of the PV4 software.

As far as I'm aware, the update suite is the same regardless of whether it's done via fault diagnosis or recall.

You might have another issue if it's been fine since the original update.

 

[Lukash]

yes. forced recall update will fix those

I'm just starting this update on a Golf at the moment, covers the vast majority of control modules. Doesn't list specific complaints/fixes though (and SEATs implementation may vary slightly)

I wonder if you get the same "readiness not reset" message right before it flashes the gateway that I tend to see.

Also, if it's a PHEV make sure your battery support is ready for the task. The cooling fans can be triggered and run for the majority of the updates, I use our Duetronic 120a unit or unplug the fans if I'm stuck with a GYS 100a.

We use GYS 100, it's an R thankfully so one less thing to worry about

Frustratingly the dealer refused to update as "not applicable" but it needs to be updated before we can adapt the towbar installation -_-

 

[James_R]

I take it there's no outstanding P4GF recall?

The necessity for the update during part replacement or addition is mental, even door control modules need the whole baseline software version updating to suit the new part.

They're claiming there’s nothing outstanding and time wise we don’t get paid until the towbar is working . Easier for us just to crack on

Yeah the UNECE cars are ridiculous aren’t they. The fact that it kicks up a stink if something as trivial as the rain sensor is incorrect/missing
