Hoping that someone on here can help me....

My 22 plate Scala had a puncture to right rear tyre after about 18 months and it was replaced with a similar quality tyre. Since then, I have had a number of 'tyre pressure warnings' for this tyre. Each time this appeared, I pulled over, checked the pressures and all were Ok. I took the vehicle to the local dealer and was informed that the system took time to learn about the replacement tyre and that it would all sort itself out.

I have used an electronic inflation device to inflate tyres to 2.4 bar (vehicle not loaded - normally 2 adult occupants only). The pressure has been validated by use of another tyre pressure gauge.

Since then, I have had regular tyre pressure warnings (sometimes to all tyres, but mainly to the same right rear). Again, tyre pressures all checked and all OK.

I took the vehicle in for the 3-year service to my Skoda dealer and asked them to check this issue. I was told that all of my tyre pressures were at 1.7 bar, when they should be at 2.4 bar !! I explained that this was not the case and that I regularly checked the tyre pressures.

When I returned home after the service, I decided to check the tyre pressures. Three were set at just over 45 PSI (3.1 bar) and the right rear was set at 51 PSI (3.5 bar). Pressures were checked by my electronic inflation device and also by getting my local tyre shop to validate my readings.

I went back to the Skoda dealer and explained all this, and was told that their tyre inflators had just been calibrated and that they were accurate. I was told that the problem was mine and not theirs.

Any suggestions as to how I move forward?

Thanks in advance.

Could the dealer you are referring to be Birchwood Eastbourne? (Not a sales agent now but they did my last service)

I have twice found that Birchwood set my tyre pressures far too high.

I reset them myself checking with 2 pencil gauges. I recently had a tyre replaced at a local tyre supplier and they checked all the pressures and they agree with my own readings.

Like you, when I mentioned it Birchwood said their equipment had been calibrated. I can only think that something is going wrong with the calibration process.

@GeoffAllen66 You say you pulled over and checked the tyre pressures.

You do not say you then reset the TPMS.

You do have to drive a bit after resetting, but learning is in a few hundred yards or a mile or 3, not a matter of days.

You checked them hot if you stopped and checked.

You then need when the are cold to check the Tyre Pressures and see if all 4 are at the pressures when you last set when cold and reset the TPMS.

Warning might not just be pessurelost, it can be a binding brake and overheating a a tyres circumference increasing because the hub / wheel is hot and the air in the tyre hotter.

No. Alarmingly, it was not them. Suggests that more than one dealer are doing it !!

Thanks for taking the time to respond. I reset the TPMS warnings as soon as i had checked the pressures.

I had not considered the temperature of the tyres when i checked the pressures, so thanks for pointing this out. Most of my driving at present is short distances locally to me, but what is weird is that the warning lights have always come on during motorway driving.

I understand that the tyre pressure system uses tyre rotation speed to determine if the pressure is wrong. If a wheel is rotating at a lower speed than the others then it can trigger the warning.

So if the air pressure is correct in the tyre, could it be either:

• the new tyre is a different brand/model and its slightly different diameter to the others (newer tread depth)? You said it was similar, but not the same.

• the new tyre requires higher or lower air pressure that the other tyres to run normally?

I have different Bridgestones on my Scala compared to the factory fitted model and the tyre shop said they prefer slightly higher 2.5bar - and I notice a difference if they get low.

Perhaps run the new tyre and 2.5bar and see?

It is not comparing rotation to others, as you can set the TPMS with the 4 tyres at different pressures, or fit an Emergency Spare with a slightly different Total Diameter / Circumference.

Or different sizes front and rear.

It is comparing with what you set at, for a change in diameter / circumference from what was logged, and enough difference.

On my Scala (2022 SEL DSG) I cannot seem to see any option to set the pressures independently of one another.

Neither can I, which I why I thought that a slightly different rotation speed at higher motorway speeds may be the issue here

Because it is the basic TPMS that started for Run Flat tyres and identifying a blow out.

Set the 4 tyres at different pressures and set the TPMS, you should not get a Warning unless one corner changes enough in size. Rotation of that wheel / tyre.

But it is still not telling you which. But the point is the front and back can be at different pressures, or circumference, or an odd one, the spare put on.

More technology on say a Superb will disable the CC or ACC, or cause issues with a tyre too much odd size out.

Here is the whole answer:

The Škoda Scala's TPMS (Tyre Pressure Monitoring System), also known as TPM+, uses data from the ABS wheel speed sensors to detect and alert the driver to a drop in tire pressure by monitoring changes in wheel radius, and some models also offer direct TPMS. 

Here's a more detailed explanation: 

• Indirect TPMS (TPM+):

  • The system uses the ABS wheel speed sensors to monitor the rotational speed of each wheel.

  • It compares the speed of each wheel to determine if there's a change in the tire's radius, which can indicate a drop in pressure.

  • If a tire pressure drop is detected, the system will alert the driver via a warning light on the dashboard.

• Direct TPMS (Some Models):

  • Some Škoda Scala models may offer a direct TPMS system, which uses sensors mounted directly in the tires.

  • These sensors measure the tire pressure and transmit the data to the car's computer.

  • If a tire pressure drop is detected, the system will alert the driver via a warning light on the dashboard.

• Recalibration:

  • Once the tire pressures are checked and corrected, the TPMS can be recalibrated through the infotainment system's options menu.

• Display:

  • The display will indicate pressure for a single person occupancy in the car and also for a fully laden vehicle.

If the car is using the ABS sensors I think all you get is a single warning and then you have to play find the tire yourself.

Obviously VW Group / Skoda do not tell you that also an increase in diameter can also be detected.

They seem to ignore that there can be wheel bearing failures or seized brake calipers causing that.

A different model, but still indirect TPMS - my Octavia does identify which wheel has triggered the warning - but the wheel ID message disappears very shortly after the warning chime - leaving just the general tyre pressure loss warning message.

Yes, that did catch me out the first few times my wife's 2015 VW Polo issued what turned out to be "ghost" low pressure warnings, the initial maybe shock, distracts you from immediately homing in on the message details being given out - then it vanishes!

I have a model 2023 Scala and the list of PR codes shows 7K1 Tire pressure monitoring system .

Can anyone confirm that this TPMS system uses the ABS sensor for checking the tire pressure and has NO sensors in the tire

or

if this PR code refers to dedicated TPMS sensors in the tires ?

Thanks for your help

Nothing in the wheel, no valve sensor.

You could always look at a valve and you would see they are just rubber valves in the rim.

No place does it show you in the car the pressure of each tyre or the temperature.

Ahh, do the external valve stems look different for a valve mounted TPMS system?

Yes, I believe that is the case for most direct TPMS - direct systems also usually display actual tyre pressures on the instrument console.

A bit late perhaps, but if the indirect system is like my Karoq it will tell you which tyre is the odd one. Certainly did for me in Austria a couple of years ago which it told me the front left was the issue.
