Tire pressure sensors?
Hi all,
A friend has a '08 A4 Avant (U.S. spec), and we were wondering if
anyone knows how reliable and accurate the tire pressure sensors are.
Are they good enough to rely on to know that your tires are soft? Or
is a good tire gauge and a weekly/monthly check still the best route?
Thanks.

To register pressure they must come through a slip ring on each hub, so its
how good are the seals and how long will they last. This technology is a by
product of motor racing, where the cars are stripped down and rebuilt after
every race...........so how long will it last in a car that does not see
that treatment. The monthly check is easy and you can then compare figures.
Why not let one tyre down and compare the electronic reading to your manual
gauge.

Which manufacturers use "slip rings" to convey TPM data? That's the first I've
heard of that, as to this point the systems I've read about used on consumer
vehicles either use RF with direct TPM sensors on the tire valve stems, or use
the same axle rotation sensors used for electronic stability controls and
antilock braking controls to indirectly derive inflation status. And those
sensors do not utilize "slip rings"...

Um, ok. I rather doubt a 40 to 90 year old farm tractor is relevant to the
question, but it certainly explains your answer
