25 miles after having 4 new Good Year Eagle NCTs fitted to my Octy Elegance, the Tyre Pressure warning light came on on the dashboard (I didn't even realise I had such a light until then). I checked all the tyres, which are all fine and at the correct pressure.

Can anyone help me to work out how to get it to go off again? Is there a connection on a wheel that might not be connected properly? Help!

Have you reset the TPM?

just make sure your tyres are all at the correct pressure, then with the ignition on hold down the tpm button for a couple of seconds and your all set.

btw, the tpm is as much use as tits on a fish

Just for background info; the TPM does not have actual pressure sensors in the wheels. It uses the ESP/ABS sensors to detect a difference in rotational speed between two wheels on the same axle, as would happen with one tyre deflated and thus rotating more quickly (squashed tyre = smaller rolling radius).

I wonder therefore what would happen if you went over a 'Stinger' deflating all four tyres at the same time; would the TPM provide an alert to this? :confused:

To illustrate just how useless TPM is, I suffered a double blowout on the off side, and it didn't even notice.

I've had several completely spurious warnings, so I've decided to ignore it now. There's no substitute for checking the pressures regularly yourself.

Maybe, they'll fit a better system in future. Who knows.

Bagpuss.

If they fit a better system, it could prove more costly. I have a friend in Florida who has a corvette, and good old Chuck has the tyre pressure monitoring system on it with sensors inside the wheels as part of the valve assembly.

When he had new tyres fitted something happened to one of the valves and as well as around $650 dollars for the tyres, he had a bill for $500 for one valve .......... oucheroo

to be fair its warned me of two very slow punctures that I would have probly not noticed till the tyre was far too under inflated to drive safely but I too have had my fair share of false warnings

No TPM needed here. the large sounding HISSSS as all the air escaped let me know id punctured my tyre by catching the side of a step in work last week

Mine will pop on at random times, but I have a quick look around and re-set it

Thanks guys- have reset it!

Disagree there - My SEAT has the TPM system and twice it has warned me of a slow puncture that may ultimately have resulted in a wrecked tyre.

Obviously, it's not as good as a full monitoring system but I consider, still worthwhile.

I wonder does the same system as the Golf which actually has a sensor in the wheel.

I think recently manufactured Golfs now have the same ESP/ABS wheel rotation sensing setup (ie no actual pressure monitor in the wheel).

Mine went off when I to had a slow puncture. Visually all 4 tyres looked inflated but on inspection found that one was down 2 psi. Never had any false warnings either.

Another vote for TPM here. Not bad for £45 IIRC.

Needs to see a drop of 3psi or more to operate, and IIRC this has to happen whilst on a journey as may not see the drop over x journeys.

Quick test is, with engine running, remove 4psi from any tyre, then test over a short drive. Refill, reset system and try next tyre.

Every tyre should gen an alarm, if not you have a fault somewhere.

You wont with 2psi. Its not a big enough difference to alter the rolling radius of the tyre. And tyre pressure can vary more than 2-3psi depending on tyre temperature anyhow.

Have to disagree with the early posts, found the TPM to be anything but useless. Last week on my way to work it went off. Stopped and looked visually at the tyres and seen no sign of any punctures or slight deflation. However upon checking the car at lunchtime it was quite obvious that i have a puncture (slow-ish).

If the TPM hadn't alerted me i'd bet i'd never have noticed the tyre is soft when i got out of work and would surely have driven off and caused who knows what damage to the tyre.

Fair point, but surely you'd have felt it when you drove off? I've had a few slow punctures in my time but if they've ever gotten to deflate the tyre that much the car slips about and just doesn't feel... right.

Really ummed and aahed about getting TPM on my L&K but didn't go for it in the end, and was the only option I didn't go for. Heard too many stories about false alarms and it being annoying and if I get a blow out, it ain't gonna help at all. I generally check my car before I drive anyway cos i'm protective but if I can't see it, I don't believe it can be that bad as it's not deflated enough to do much damage. That, and i'll feel it if it isn't correct.

Was a bit gutted it wasn't a general sensor thing like the renault ones, but i gather they were pony anyway from what i've since read: if you put the spare wheel on, it would still read the tyre in the boot.

Heading across Europe to Poland next week and this trip was planned before I ordered new car so I specced TPM as peace of mind with the view that if I pick up a minor puncture on the autobahn then I may have half a chance of a temporary fix with tyre repair aerosol before the tyre gets shredded. Hopefully it may never happen ., but under these circumstances it would definitly be worth the extra few quid it cost in the first place.

GK - NEVER, EVER use that repair can. FUBARs the tyre, meaning you must have a new one (if it works at all), and you cant safely do more than 30mph.

Change the tyre, and get repaired if you get a puncture.

Thanks Gadgetman for that good advice. That will be one less thing to pack .

I have never used one of these aerosols myself yet, The intention was just for peace of mind.

Cheers, G.K.

TPM came standard on my vRS. It's now 3 months old and just done 10k and not one false alarm, wonder if the later ones are improved....

Had the light go off a week back, stopped the car and gave the wheels a once over(visually)....did'nt see any issue so just stopped off at the next pump and checked the air pressure just incase

then had the same problem 3 days back and got the tyres checked and what do u know.....one of the tyres had a slow puncture with 2 nails jammed in....TPM pretty much avoided any major tyre damage.....thumbs up from me

I agree i would have felt it when i drove off but with very little side wall on 18" tyres it could well have damaged the tyre even on the shortest of journeys.

dont think mine has ever gone off either.
