Just wondering, as when I drove to work today the warning light came up, so I duly pulled over and checked the pressures with a 12v guage/pump- One of the rears was down to 27.5psi but the others were around 30-32psi. Only just brought the car from Skoda on wednesday and admitedlty havent checked the pressures as they said thast they had done it. Would this change in psi make the warning light come on?

Also what presures do people keep their tyres at- VRS 225/40 R18?

Let's put it this way: it's the only thing I didn't spec on my car after reading about it!

Pain in the @rse!

Manual says if the tyre inflation pressure of at least one wheel is insufficiently inflated in comparison to the stored basic value, the warning light lights

up. But you'd already know that having read it.

Hi,

I had this happen on mine for the first time about 12 months ago.

Checked pressure and it was one tyre at 27psi.

I run the rears at 31 and the fronts at 30 normally.

Turned out to be a nail in the middle of the tyre, so I got it repaired.

Useful thing to have IMO.

Mine is dead accurate and i consider it to be worthwhile. The only time mine has ever signalled is when a tyre is flat through a leaky valve or nail etc or when the temperature rises or drops dramatically this is obviously down to the air inside the tyre expanding or contracting. Its a good early warning system that prevents you shredding tyres and can usually get the nail hole repaired where as if you didn't know it would be too late and the nail would probably rip the tyre to pieces.

Mine saved my neck on Snake Pass last week. Hit a bad pothole but didn't think it had caused a problem. Was considering an overtaking manoeuvre when the tyre pressure light came on. Pulled over to find a massive tear in the sidewall. Hate to think what could have happened if I hadn't had the sensors.

Mine has been pretty good over the years. It's picked up a couple of slow punctures on mine usually when it's dropped by 2psi relative to the others.

You have to remember to reset it every time you pump up the tyres.

I have never had mine come on. I had new tyres fitted last week and forgot to reset the system, yet the light didn't come on. I wonder if it even works?

Good when it works, but LOTS of moans on here about it not lighting up because the leak is too slow or it doesn't want to reset properly or other things.

Was hoping it would be like the Renault version which told you the actual tyre pressure, but was disappointed, obvously.

Having owned 7 renaults it would most likely malfunction thought at some point and cause a catestrophic failure of the electrical system. As with all things you only get people moaning when something doesn't work as they expected it to or the rare ocasions it fails to operate as designed. Yet i would say the thousands of times its correctly alerted the driver to impending doom wouldn't get typed on here as its to be expected. Touch wood its saved my bacon more than once which is reward enough for the addition even though i never specced it on the car. Not sure if its on my blackline though come to think of it i never checked. Hope it is.

Seems to work well on mine and 3psi difference is usually a sign of something not right

Mine has come on due to slow punture, new tyres fitted and forgot to reset does what it states on the tin - nice little saftey feature

Run std pressures in mine as per the fuel cap

Sure it 2.2 bar rears and either 2 or 2.1 fronts

Upto 2.2 front and 3bar rears fully loaded and I got about 2.5/6 bar when trailering the track beastie

I used to run 32 psi all round on my vRS hatch, seemed to work well at that pressure - measured using one of those little pressure pens from Halfruds. I never use an airline.

I wouldn't usually spec the tyre pressure sensor until I had two slow punctures on the same tyre, one after a repair. The tyre didn't look particularly under inflated but the light came on so I checked the pressure with the pen and it was down to about 25 psi on both occasions.

I was very glad of this notification as I could've easily blatted off to work and either not made it to work or come out after work to find it completely flat - it gave me chance to check and rectify.

Mine came on the other week when i had a punchure & the preasure had dropped to 15psi. It has come on once a day after i had new tyres fitted & i had reset it but i checked the preasure's & they were fine so i reset it again & it never came back on. (until the punchure a year later).

I think from some time this year it is a advise on your mot if a sensor has stopped working. From next year it WILL fail .

this is only on 2012 (12 plate) onwards if fitted,

I did say from THIS year.

The latest commission directive, 2010/48/EU, states that from January 2012, any vehicle originally fitted with TPMS will have to have it fully operable in order to pass the annual MOT test. This will then mean that even one faulty sensor will be enough to score a 'fail'. Sensor

How would they know if it is an original fit rather than retrofit? Is the spec to that level of detail stored in the database? And I'm not even sure you need a reset button for it to work- I've seen articles suggesting its there anyway with some abs modules, and resettable in vcds.

In a way I'd want it included anyway, I think its a really simple but useful safety feature.

The Octavia uses an indirect system not individual sensors

Doesn't really affect the Octy - we have a fairly basic system that works on the rotation of the wheels (which is why it's not particularly accurate and doesn't flag at all if all the tyres gradually deflate).

Some cars have proper sensors in the wheels which measure te actual pressures. Problem is they're easily damaged when getting tyres fitted, and can be expensive to replace. My old man had a couple go agree getting new tyres (different places) and it cost him £140 each time. The next time it happened he got them all coded out rather than have another one replaced.

Well it wasn't lying! I have just found a screw sticking out of the tyre although it has not lost any more pressure since I topped it up on the way to work. Good thing really but I only brought a new car on wednesday and prob have to replace a new tyre today as it is right on the edge of the tyre!

Sorry to hear your tyre is f**ked but i bet your now glad you have the tyre monitoring fitted. Im not sure what blackspaven was on about it not being worthwhile. I think its an essential safety feature. Sure it might give some people a false reading now and again but thats not a reason to not have it fitted afterall the tyres are the only thing that connects your vehicle to the tarmac so any monitoring is essential IMHO. Its probably saved your bacon as i doubt you would have noticed that screw otherwise.

The system is worthwhile then.

As I say, exactly same as happened to me.

Fortunately, mine could be repaired.

As EddieNL pointed out the system is indirect TPM. It uses the ESP/ABS sensors to monitor the rolling circumference of all four wheels, if there is a deviation it will throw a warning but its then up to you to check all the tyres.

The more advanced system uses battery powered RF tyre valves which are able to feed back the individual tyre pressures to the cars ECU by radio and offers real time monitoring of each tyre.

Ive had the passive system on my last 3 cars and on the whole its been useful, but it has gone off before without there being anything wrong with any of the tyres.

If it was essential it would be fitted as standard. I said it wasn't my preference to have it fitted as I don't think it's that great from what i've read, but feel free to go ahead and judge other people as quickly as you have done me by the choices I make.

I CHOSE not to have it after reading several open questions about people's OPINIONS of it having had it fitted to their car. They gave pros and cons and I MADE A CHOICE.

What a lovely world we'd live in if everyone did exactly the same and slated anyone thinking otherwise. :(

I did wonder how it worked. (thanks for the info)

Like I said 'I' Think its essential for 'my car' i respect your decision to not have it and would never preach to others. However i think im within the normal operating parameters of an open forum to call into question your judgement and say that 'I think' its a bit naive at best seeing as its safety related to tell another new member they are a "pain in the @ss". If it was optional sunroof etc. then its just down to personal taste and i wouldn't have bothered commenting. I think i remember you telling me that your car was better than a VRS blackline because you could spec curtain airbags in it. Well now i see why you might need curtain airbags seeing as you could be driving round with nails in your tyres and not know about it. Don't take it so personal i was merely redressing the balance and giving the OP an alternative point of view turns out i was right. Oh and like i said i thought it was Standard equipment as it was in mine when i bought it.

P.S. your boxer in the front seat is epic mine used to sit proud like that in mine. just impossible to get the slobber of the interior though.
