I'm using the car regularly so I wonder why it would go into parking mode. It just seems strange that the light comes on and goes out just as it should and the display comes on with recommended pressures but actual pressures are all 0. I've been looking for a TPMS module but I don't think there is one, just a receiver. The old SOS limited function message is coming up every now and then and maybe that has something to do with it. New battery on it's way

Well we got there in the end Kot,(almost) I removed the dashcam hard wiring and TPMS readings came back. Tried powering the camera from the cigarette lighter socket and they disappeared again. Disconnected it and they came back. It looks like the compromise might be TPMS or dashcam which is fair enough as long as I'm not causing any damage by blocking the TPMS signals or whatever. I hardwired the camera using the power adapter that came with it and the same adapter is used to power it from the cig lighter socket. Opinion on a dash cam forum is that it's the power adapter that causes the interference and they recommend powering it from a USB socket. I'll try that next and maybe a proper hardwire kit instead of my home made one.

Well, after much testing and experimenting with a proper hardwire kit, a different camera from my other car and rear camera on and off. The conclusion was: Any camera and power supply = TPMS reading zero.
