From what I've read elsewhere it doesn't work like that - the app <> car communications still go through the eSIM (via VW servers) and not wifi.

More reliable / faster update download compared to 4G.
Exactly, this is my use case. We have no mobile signal where we live. Plus the OTA element.

Do you have a reference for that?
If the case then agreed can't see much point.
Does anybody have no 4G but can still the car by WiFi?

I’ll test when our car comes back. Might be a few weeks 😀

Looks great. Will order a set. Happy motoring...or the equivalent EV term:)

A guy who had his car on his WiFi and scanned the network traffic going to and from the car to see what it was doing, there was nothing app-related. He also discovered that the car goes to sleep (ie. drops off his WiFi network) after a short period of time, which is no use for car <> app communications that you could want at any time.

I can’t remember where I read it.

I think it’s more likely that WiFi will be used for OTA.

I concur. Mine dropped off the wifi when I locked the car (or very soon afterwards). But that's not to say it doesn't wake up periodically and call home. I'll check my firewall-router logs after I get it back from the dealer following the protracted 2.1 update / control unit failure.

I wish I understood this whole business better.
Does anyone have a link handy so I can expand my knowledge regarding how 4G is utilized in the car and software interface? Do we have unlimited mobile data on our eSim? Is there a point in time when we will need to pay for data?
I looked around the net earlier in the week and was offered a 2G data free trial that I thought was via a VW link but decided to reseach it more hear first.

Hello guys, new to this forum. I have an ID.4 that does not connect to 4G at my house. I found this thread via Google.

Did you manage to resolve the missing 3G/4G connection on your car? If so, how was this done?

Does it connect elsewhere, and the problem is only at your home?

Have you installed the We Connect ID app on your phone and configured it to connect to your car? Does it connect okay?

Have you tried connecting the car to your home WiFi network?

If your car shows it has a 3G or 4G signal when away from your home, but no signal at your home, then it must be that the cellular signal that your car is using is too weak at your home location. VW partners with Cubic Telecom, who in turn piggyback in the UK on the EE network. If your home location has a strong EE signal then so should your car.

Hi
Thank you for the response.

Yes it connects elsewhere. Right now the car is at my wife's place of work and I can connect to it via WeConnect ID. I successfully started air con remotely yesterday.

I have tried connecting it to my home wi-fi, it appears to connect OK in that it appears on my wi-fi network and shows up as connected in the car. This makes no difference to connectivity, no connection can be made using WeConnect ID.

My car shows 4-bars with an E where 3G or 4G should be when parked at home. I have a 4-bar 4G EE signal on my mobile phone at home (I can see the mast from my back window).

Does this mean I have a fault?

Bear in mine the WeConnectID app is flaky, so most obvious explanation is that it is just coincidence that the app works at your wife's place of work but not at home. Unless there are other differences like at work the ID.3 is charging, at home it is not, as this will change response of the ID.3.
I assume at your wife's place of work the app is only able to communicate via 4G EE, and you have 4G EE at home so the app should work at home just the same.
However, at home your ID.3 will connect to your home wi-fi, so if car tries to use wi-fi to communicate to VW servers and your router blocks the communication then the app wouldn't work when ID.3 at home. It would make sense for car to use wi-fi when possible, as there is no charge to VW for this, whereas there is for 4G. But, we don't have any evidence that ID.3 uses wi-fi for communication back to VW servers.
If I was you I would disconnect your ID.3 from your home wi-fi where you have strong 4G signal and try to connect via the app, if it works straight away then suggests car was trying to use wi-fi, if not then just keep trying until it does connect.
ID.3 will be awake when driving or charging, however my ID.3 sat at dealer's only appears to communicate with the VW servers about every 14 hours. So it appears only communication is only possible under those conditions.

That is E for EDGE which is one of the 2G specs, so you don't even have a 3G signal - doesn't sound like a fault, just a poor signal.

Sorry missed that E, agreed just a poor signal.

I think I have finally worked out the purpose of having a Wi-Fi connection from your ID3 to your home router, it stops the ‘internet radio is unavailable’ error from appearing on start up. :idea:

OK the car thinks it has an Edge connection (which is too slow to be useful) but where the car is parked at home, my phone has 4-bars of EE 4G. Why does my car not have the same? At my wife's place of work, the car shows a 4G signal in the infotainment screen and her EE phone has a 4G signal.

I think this is a fault on the car as there is a strong EE 4G signal at my house, but the car only shows an Edge connection?

Does the ID.3 use the EE network where you live?

I heard VW use 2 networks in the UK, but not sure which ones and where it uses each...

Sorry I didn't answer immediately. I don't know definitely which network VW ID family cars use, but everything I've seen talks about EE. My dealer has thrown their hands up and said they have no idea, pointed me at the WeConnect helpline. So currently seeing what they have to say about not being able to connect when the car is on the drive. (sent over a bunch of photos yesterday)

At last I figured out.
ID doesn't connect to TKIP (Temporal Key Integrity Protocol) protocol, but needs AES (Advanced Encryption Standard).
I have TP-Link repeater, and it has only TKIP.
To another router it connects without problems.
