Yep, I am convinced there is still an underlying issue that they haven't addressed - I guess they will sometime...
That is really weird. I literally went and sat in my car now and pressed the right button. Nothing. Then I pressed the left button and after 20 seconds the SOS light started to flash. Why is this working on the right button for you and left button for me!?!?!? Mind explode!!!!It's not the button on the left, it's the one on the right (the one nearest the knob).
OK @stevelup then I'm inclined to give you the benefit of doubt, especially as the instructions also say so. I'll re-test again today and wait much longer after pressing and holding the right side button (front de-mist). I'll report back again later. I'm hopeful that I'm wrong and you're right!I hate those ‘buttons’. Worst thing in the car. Why they couldn’t just have five buttons instead of that stupid touch sensitive haptic rubbish?
All I can tell you is that the instructions say front demist and I’ve definitely successfully reset mine with that inner button.
how to over engineer a problem, probably exactly thatI've reset it a couple of times by using the inner (front demist) button, but I counted to 20 before the SOS light started flashing red. You do need to press it down hard enough to feel a slight click. I wonder there's a single button under there to detect movement and give feedback, and the touch sensitive layer just determines which of the two buttons you press?
A quick call to Roadside Connect seems to fix the issue for me. They don’t do anything - just the process of calling them seems to reset the connection.I have latest OTA update, and LTE not connecting, just the x symbol.
TCAM reset not working ... I have tried holding the inner demist button down for up to a minute even, the. I have also tried the outer (rear) demist button. Both times ensuring I pressed sufficiently for the click.
I am parked. Have tried with WiFi on and connected via my iPhone hotspot and also off.
Have tried also when moving.
At no time does the SoS button flash red 🆘.
Polestar Roadside Connect/Assistance do not work on anything to do with connectivity, meanwhile Polestar CS are not open now because of the Bank Holiday.
Anyone any ideas how else to force TCAM reset for LTE connectivity?
NEW TCAM RESET METHOD
I managed to talk to Polestar today. The TCAM reset method never worked for me, as discussed in my earlier post, but this new method did. P* CS talked me through the steps in real time.
I was told this is the way that always works and should be used to ensure the TCAM not only reboots but also pulls across the TCAM module update properly from the last major OTA software update. Once reset and updated that way the CS rep said they believe this new update will provide a reliable long term fix.
1. Stop the car. Make sure in park.
2. Hold HOME button on main screen until it does a reset of the infotainment system.
3. Immediately after the reboot has finished, hold down the front window demist button (1st button on left of play/pause for at least 15 seconds.
4. Note: I was counting slowly and got to 30 seconds without an SOS light flashing, before the CS person said to me that’s enough, let go.
5. Wait patiently a few seconds and hey presto the SoS started flashing. Note it did not start flashing until I had release the button and waited a while.
6. Once flashing stops, after about another 10-15s the 4G/LTE display started changing. For me it flickered from 4G to LTE, then the empty strength signal changed to full, and then the ‘x’ disappeared and I had full connectivity.
Doing the TCAM update immediately after the infotainment reset is key. For others maybe the SoS will start flashing while holding the button, in which case then let go of the button, but for me it would not start flashing until I let go. I was told a minimum of 15s should be enough but I held it for about 30.
It has been stable since, so far.
I know some have been able to do TCAM resets without this and have even had to do it many times. Perhaps??? Only if you reset the infotainment first will it actually get the TCAM to apply the latest update to the TCAM module to make it reliable?
Anyhow, it worked for me and I hope it works for everyone else who has problems.
