Strange. My 2019 etron has wireless CarPlay.The 2019 X5 we traded for this e-tron had both wireless CarPlay and could show individual tire pressures. Pretty big miss here.
Yes, as does ours, I'm speaking to the lack of showing each individual tire pressure. Posts above indicated that showing tire pressures wasn't possible due to wireless CarPlay. Our 2019 X5 had both with no issues.Strange. My 2019 etron has wireless CarPlay.
Maybe someone who's had a warning can chime in here. Let's say one tire does go low, does the car tell you which tire?I think that you have to set the pressure correctly for the load, temperature and tyre type then register that as a baseline. The car must then look for a deviation in rotational speed against power delivered to the wheel in order to detect if the tyre is going flat. Perhaps this is an adequate solution? Not so sure it’s very useful to know the exact pressure figure but I’ve never owned a car with that feature.

I always fit Tyre pal pressure sensors to my cars. These give a constant pressure and temperature reading. Unlike the early tyre pressure monitoring systems which required a pressure sensor within the tyre these simply fit externally to the valve. They are very accurate too!I think that you have to set the pressure correctly for the load, temperature and tyre type then register that as a baseline.

Based on my experience with the indirect TPMS in my e-Tron and my previous A4, if it simply says "loss of pressure" that simply means the pressure hit that threshold in multiple tires. If it was specific tire that suddenly lost pressure, it will tell you which one and give a more severe warning. I experienced that scenario after getting a nail in one of the tires on my A4.I had my first experience with the TPMS this morning during my commute to the office. The "Loss of Pressure" warning flashed to inform me that I'd experienced a loss of pressure. Nothing more. It did not indicate which tire or how significant of a pressure change. It simply directed me to adjust the pressures and resave them in the system.
I did a quick visual review of all four tires when I got to the office, and I did not see anything abnormal. It's possible this morning's cooler weather caused enough of a psi drop on a tire to trigger the warning. I'll connect my mobile inflator to check pressures and correct inflations when I get home this evening.
I've had several cars and SUV's in the last decade that indicated pressures by tire. And as for the Wireless CarPlay hypothesis, we have a 2017 X5 with a much better TPMS system and Wireless CarPlay. We've not had any conflicts or issues between the two.
I love my e-tron, but it seems like Audi cut corners for the TPMS. This TPMS is rather worthless.
Is there any chance it could be upgraded through a software update?
Thanks. I checked all four tire pressures after I got home last evening. All pressures were within 1.5psi of what Audi recommends. Still, I inflated them to the appropriate pressures per the sticker inside the driver’s door and saved them in the MMI.Based on my experience with the indirect TPMS in my e-Tron and my previous A4, if it simply says "loss of pressure" that simply means the pressure hit that threshold in multiple tires.

In your case, just fill the tires to the correct PSI when the tires are cold and store the pressure the TPMS through the MMI.
For your other cars that displayed the TPMS, that was a direct system which has wireless sensors in the wheels. It has the advantage of giving a direct readout, but the disadvantage of have to replace them every so often, or dealing with bad ones, which I've had happen.
Both systems are quite accurate in determining problem situations, but each has their own unique advantages and disadvantages. I think it's really 6 of one, half a dozen of another...
It's very possible the dealer originally overinflated them and stored the pressure at that higher setting. I had that happen.Thanks. I checked all four tire pressures after I got home last evening.
