Had the TPMS alarm go off yesterday, checked the tyre and could not find any damage/nails etc and pumped back up, this morning got TPMS alarm again on same wheel, checked again and pumped up, have checked the pressure this evening and it has not dropped since 07:30 this morning and have done approx 300 miles too..

 

Maybe a sticking valve second time, but what caused the alarm in the first place.

After correcting the pressure are you storing the pressures again on the TPMS system, otherwise it will keep triggering.

+ 1 from me.

 

When you get the car symbol with the orange wheels press either left or right arrow and you can reset the TPMS pressures.

Yes, and on both alarms the pressure had dropped, but it has held for the last 12 hrs, will check in the morning before setting off.

Tighten the valve core.

The TPMS on Skoda -and most VAG cars including VW and Audi - works on comparing wheel rotation to detect tyre pressure differences via the ABS (a flat tyre has a smaller diameter and will therefore rotate faster than the others) and does not monitor the actual tyre pressures. The disadvantage of this apart from lack of accuracy is it can be triggered by wheel spin to give false alarms. Most low to medium price cars use this system, the more sophisticated designs actually measure the tyre pressure by means of sensors located inside the wheel rim and transmit the information by radio to the car's on board computer.

Should really be referred to as tyre deflation detection as its not true pressure monitoring....TPMS is a little misleading as this refers to the system tim refers to above.

Those systems are still not perfect however, more to go wrong.....valves can go faulty, valve batteries fail, can get broken in the process of a tyre change etc etc. Nice that it tells you exact pressures though and is naturally more accurate.

I suppose the nice thing with the Mk7 based system is that it does at least tell you now which tyre is the issue rather than just saying there is a probllem leaving you to determine which wheel has the issue...not always that easy to determine.

The Skoda system is also reliant on the user resetting the system when the tyre pressures are checked - which seems to be the root cause of many of the questions on this forum.

Worst combination ever - TPMS and run-flat low profile tyres, as on my 1-series.  You can't tell the difference between flat and inflated, so when the TPMS goes off, you don't know whether to believe it or not anyway.

 

And as for telling me which tyre - it started by telling me it was all 4 tyres, then after a mile or so it decided it was actually only one of them.

From 2014 model year BMW have fitted the more sophisticated pressure monitoring system - at least on the 3 series, not sure about the other models. With "proper" TPMS you also have to be very careful when changing tyres, as the sensors inside the wheel rim can be easily damaged.

You can't get Kwikker than a Kwik Fit Fitter LOL

One other annoying thing with real TPMS......quite often the spare tyre doesnt have a transponder so whilst running on a spare the car complains all the while that there is a sensor problem.....mate had this on his A6 and was v annoying.

Ive taken my vrs on track a few times now and its always either coming up with tpms errors or loss of pressure in one tire. Checked it plenty of times and ita always .5psi different. Dont think the system likes track

I assume that you don't go to the track to drive like an old lady, so of course the TMS is likely to get confused.  Take a look at the Infra Red images of the tyres in F1 and you can see how driving around a track at high speed can cause a massive difference in temperature in different tyres.  Difference in temperature causes differences in amount tyres are inflated, causes TPMS to measure differences in rotation.

 

By the time you come to measure the tyre pessures they have cooled somewhat and don't show the same differences.

 

Relax and enjoy your track days - you've paid for them, after all.

When I swapped my front and rear wheels over (shocking wear on fronts after 8k) the TPMS had a whinge.

Reading all these posts and replies it seems that on the Skoda (mine is a new Superb Estate 2014 model) they do not use Tyre Pressure Monitoring Valves ? can anyone confirm this please. I am looking to change to winter types and new alloys and I am getting conflicting views from wheel suppliers. One says TPMV's are required another say's not. These things cost £160-320 for 4 wheels.

No they don't.

As said by Andyvee the Octavia does not use valves to sense pressure. You have a Superb and I would check on the Superb forum.

And it isn't called TPMS anymore, according to my car it is Tyre Pressure Loss Indication

System on my old Superb II was the same as Octy III so I would say you ok to just change tyres but remember to reset the system.

That seems a more appropriate name since the system doesn't actually know what your pressures are.

Probably something to do with the new EU regulations

not got my octy yet, it's not been built even yet,

 

but I assume it will have TPMS on it, as it's now law.... 

 

I've got winter rims and tyres to put on it (they are 16" that I have run on my altea)

 

will I need to do anything, reading other comments there aren't sensors to worry about, but do I need to teach the system when you swap wheels?

 

thanks

I had a puncture the other day and the TPMS didn't show a fault until I put a winter tyre on to keep me going until I got the puncture fixed. I have a SS spare but why use that when there's a full size one in the garage at home!    To be fair I was 200 yds from home so it hadn't gone down much in that time.

 

It's a different make of tyre (obviously), although the same size and has similar mileage on it.  Odd that the pressures need to be reset if it's measuring wheel rotation rather than actual pressure.  I assume the system counts revolutions from that point and stores any differences as being 'normal'.

 

On a positive note, the fact TPMS works like it does is a benefit for those of us who have a spare set of winter wheels and tyres as the re is no need to buy the in-tyre gizmos to measure the pressures.
