Hi 

has anyone else experienced this issue, or can anyone advise the best course of action. 
 

I recently replaced both rear tyres on my Skoda Fabia mk4 due to a nail found it one of the 2 tyres. I decided to replace both, however since doing so and having reset the tyre pressure notification, I have found that it has since come back on twice after around 60 miles after resetting it. 
the tyre pressure are in line with the recommended pressure and neither or the 2 tyres have lost any pressure, however the notification has still come back on twice. 
 

Any advice would be appreciated. 
 

thanks

Does it say which tyre it is on the infotainment system?

 

Start by checking ALL the tyre pressures when the tyres are cold, and then reset the TPMS system.

Then check the pressures in a week or if/when the TPMS warning comes back on.

 

Thanks. AG Falco

Do the new tyre sizes moulded into the sidewalls exactly match the fronts?

Do you know if your TPMS is direct or indirect type? - To explain, the indirect type operates by calculating the tyre rotational speed through the ABS system, while the direct system reads actual tyre pressures via wireless sensors fitted to the wheels.

@DR79 Are you sure your Fabia is a Mk IV and not a facelift Mk 3? Your title section has the year as 2020.

I had a problem when I towed with my Yeti, I put the tyre pressures up for a full car and after half an hour The tyre warning light came on.

I immediately pulled into a handy services and checked each car tyre and found the pressures had increased (over the set pressures)

due to friction. Reset pressures  and continued with no more problems

 

*ugger, I left my car in the sun while I did some shopping (20 to 30 minutes)

When I came back I drove the short distance home and the tyre pressure warning

came up. I took tyre pressures  and the tyre in the sun pressure was highest.

Reset warning after the tyres cooled and away it went.

I will check my tyres all round when I can find the space to park on the road.

* Leave Nothing to Chance*

My understanding was that VAG vehicles generally do not have 'direct' TPMS (where inflation-pressure sensors are fitted to the base of each tyre valve) but have, instead, 'indirect' TPMS that exploits the vehicle's ABS and (basically) compares the rotational speed of each road-wheel against an overall setting.

 

Direct TPMS permits actual tyre pressures to be displayed. Indirect TPMS does not, but may be able to indicate which wheel(s) there's a problem with. 

 

If a vehicle has direct TPMS, there is normally no driver-operable RESET facility. If a vehicle has indirect TPMS, there will be a driver-operable RESET capability. 

 

The two TPMS types are explained here

 

https://www.schradertpms.com/en-gb/driver-education/direct-tpms-versus-indirect-tpms

 

Unsurprisingly Schrader 'likes' direct TPMS as the company has a vested interest. Personally, I 'like' indirect TPMS, as there are no tyre-valve sensors, but I fully recognise this system's limitations.

 

In the past, where a vehicle has not had TPMS, I've used TyreSafe products

 

https://www.tyresafe.org/the-checks/

 

This involves fitting a sensor to the top of each tyre valve and allow inflation-pressure data to be read on a small display-screen in the cab.

The indirect system on my wife's 2015 Mk3 Fabia seems to have very wide parameter(s) it should never be relied on and tyre pressures checked as usual, the one on my wife's car was very tardy in throwing up a warning, not really suitable for those that rely on the car's or other computers to tell them or remind them to drive and maintain the vehicle they are driving on the roads we all travel on.

 

The system really came about as a common fitment and no mandatory because there were run flat tyres being fitted and some idiots could not detect a puncture and required a warning.

 

The simple system is pretty good really but yet still some people are that simple as to not just understand how it works, oe might not work, or they can not be bothered to read an Owners Manual.

Or to check tyre pressures and set them occasionally and reset the TPMS.   Some people want warnings for everything, low oil, low coolant, low windscreen wash, low fuel, or even a tyre at a lower pressure, so less circumference,  or even more circumference because a brake is binding or a bearing going, heating the hub, so the wheel so expanding the air in the tyre.

This can cause a warning, and then if not checked until the tyres have cooled the pressure might look ok.  Or as last set.

This Wikipedia entry relates to TPMS

 

https://en.wikipedia.org/wiki/Tire-pressure_monitoring_system

 

The "United States" section includes the statement below that may explain why indirect TPMS (certainly older versions of indirect TPMS) can be slow to provide warnings of tyre-pressure loss. 

 

The final rule requires that the driver be given a warning when tire pressure is 25 percent or more below the vehicle manufacturer's recommended cold tire inflation pressure (placard pressure) for one to four tires.

 

A while back, the day before I was due to drive several hundred miles mostly on UK motorways, I checked over our Skoda Roomster and, discovering that the pressure in one of the front tyres was 26psi rather than the 32psi in the other three tyres, a quick inspection revealed a screw embedded in the tread. There had been no warnings from the Roomster's indirect TPMS, but If an up-to-25% reduction is 'allowable' before a warning is issued, the 32psi reduction to 26psi would have (just) been acceptable.

 

I'm a moderator on a motorhome-related UK forum with over 23k postings to my name. UK motorhome owners have something of an obsession with tyres and tyre pressures as the recommended tyre inflation-pressures are generally high (70-80psi) and, if the motorhome is light or lightly loaded, the resultant ride quality can be bone-shakingly harsh. Historically, It's been common practice for UK motorhome owners to take their vehicle to a weigh-bridge and, based on the measured axle-loadings, reduce the tyre pressures accordingly after taking advice from the tyres' manufacturer. This was fine until direct TPMS began to be fitted as standard to most new UK motorhomes, when it became evident  that even a small downwards alteration (say 0.5%) from the recommended high pressures that had been factory-input to the TPMS would trigger low-pressure warnings. So the moral of this tale is that, if a driver wants a system that will provide pressure-drop warnings earlier rather than later, direct TPMS is the better option.

I was aware of the 25% figure but that doesn't mean necessarily that's what's on a 2015 or 2024(?) system, I think I've seen other computer systems on the car have a 25% margin but I don't know if that's correct but I do know designers, engineers and computer programmers don't always get everything right (despite what some of them believe in their own minds). 25% to me seems a wide margin for many things.

 

I checked the tyres on the Fabia only the other day and the two rear tyres were slightly down, they are the newer tyres but as with the front have been OK, perhaps like me they don't do well in this heat.

 

Personally I've never had a car with TPMS and have somehow survived, coming from a time when the driver was expected to check things and there wasn't a button on the dash that does everything for you.  I'm more towards, but not at, the sharp spike on the steering wheel end of car and driver safety but I don't expect newer drivers who have never owned an old banger from the last century to be the same or understand this.

 

I don't want a warning light but I do think the clever German engineers could have put something like a flexible measuring tag on the cap of the windscreen washer bottle as it is out of sight and only the filler tube neck on view but obviously that add to the build cost and eats into profits, dividends and expense accounts.

 

People should check their tyre condition before every trip (in theory) it is when all is said and done your only contact with 

the road (and life!)

I checked and logged tyre pressures on the works van I drove with 5-6 people aboard. I took it for an MOT and  the inside

of one tyre had a long bubble (about 8") The tyres were new 3 months previously and my daily checks had shown

pressures were checked daily so all tyres were replaced free of charge by the suppliers. With another make!!

Have you checked the front tyre pressures?
