Tyre Monitor - Possible Group Buy?....
SteveP:
The person who has this already is Ben (Username TheWheelMan).

I'd seriously think about this. Would save me having to check the tyre pressures manually. Plus my rims need refurbing and tyres need replacing soon.
RedRobin:
^^^^
@ SteveP - Thanks - I'll try and find out what he thinks of it etc :happy2:
@ stealth - Methinks one could use it at the air top-up places too - More reliable than their data I expect.
Our GTI's already have an onboard tyre monitor but it only tells you you've lost a certain amount of pressure and not how much or which tyre. It's only designed as a safety measure against a slow puncture while driving.

Just so you know, the TPMS on the GTI is not an "active" pressure based system. It measures the rolling radius of the wheel through the use of the ABS sensors. This renders it very inaccurate, and slow to respond. As a tyre pressure warning system goes, it's not very effective.
US-issue GTIs get an active TPMS system with a sensor in each wheel; however, the cost to retrofit it in a EU-spec Mk5 is around US$1000, at least when I investigated this a couple of years ago.
This seems like a highly cost-effective and neat way of getting an active TPMS system working. Two things I'd like to know about this though: 1) What wireless protocol does it use? I'd be money it's ZigBee, but I'm not sure; other things could interfere with your phone or bluetooth or whatever and 2) What resolution is the sensor?

a little bit more info on these-hope you don't mind RR
