I'm trying to figure out if I have a TPMS issue or not, and my search turned up this thread, so here goes:
When I took delivery of my RS back in early April, I was surprised that the TPMS readings were down to 1/10th of a pound, and also surprised that the pressure stayed virtually constant for the first 500 miles or so. I've never had TPMS, so didn't know what to expect, but it started out great!
Over the past 200-300 miles, however, I've been fighting slightly low readings (35.2 front/41.3 rear, +/-, in that neighborhood), and no amount of topping off, bleeding and re-filling or anything seems to move the numbers in the TFT. I have 3 "stick" gauges, a digital version and the digital readings I get from my Ryobi battery-powered inflator, and they all confirm I'm now in the 38 front/44 rear range.
The TFT seems stuck where it was, and it won't give me a reading at all until I'm about 1/2 mile or so underway, which doesn't seem to be the state of things early on, when all I had to do was hit the button and toggle through the screens. Just double-checked it before writing this and no readings in any of the relevant screens. The "icon" with the exclamation mark shows "WHITE", which as far as I can tell doesn't mean anything.
I called Engle, couldn't get Ed in Service so I chatted with Peter (sales), who said they're just a general guideline, notoriously unreliable from an absolute accuracy standpoint and are best cross-checked with a good, old fashioned pencil-type gauge with a "square" (not flat) slider. I have two of those and they both say I'm above minimum.
So, my questions are: 1) Is it normal to NOT get a reading through the TFT at all while sitting still (engine off); and 2) Should I just not sweat it if I'm getting good cross-checks with other devices?
