....I don't mind at all, Andy - In fact I welcome it as it informs us all better.

This pic on your posted link shows its size better : -

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 bet 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?

....Haven't you got something better to do such as resurrecting ancient Soviet military hardware? :grin:
Just joking! But I don't know the answers to your questions - If no-one else posts answers I can try and find out tomorrow.
:happy2:

Apparently, from 2012 all NEW VEHICLES sold in the UK will be fitted with a Tyre Pressure Monitoring System when they leave the factory.
But I wonder if they'll be any better (more accurate) than the system VW already have in our GTI's. And why wait until 2012 FFS!?

EU law, same with the DRLs.
They will be much more accurate (both in terms of response and resolution) that the passive TPMS that we have as it will be an active system using in-wheel sensors.
chungster:
thats an awful lot of money vs buying a gauge and checking it regularly.
I know they sponsor the Time Attack series and some of the racers are using it.
But for daily driving...is it really VFM?
i look at my tyres every day before i set off for work...just a quick glance for bulges and deflation.
then check the pressure every other week.
