Hi folks,
My Roadster 2.0 goes in for its annual maintenance tomorrow, and I'm thinking of asking them to check out the rear TPMS system.
I have an OVMS module installed, and noticed that almost always the rear tires read exactly the same pressure and temperature. The fronts are nearly always slightly different from each other, both in temperature and pressure. The VMS display of the tire parameters shows the same behavior, though with slightly less precision.
It seems to me that there's something odd going on with the rears, but I can't imagine what sort of condition would cause it, since each tire has a unique ID, and the car should record each tire individually. It's not like there's a crossed or shorted wire somewhere that could cause this. And, that the numbers do occasionally differ, suggests that the data is, in fact, live and independent.
Any thoughts? Is this worth bringing up with the service guys, or would I be wasting their time? I know I could let some air in/out of one of the tires to check, but it's late, and there may be more going on here than a quick experiment could determine...
