Skoda tyre pressure monitor

[Alanphe]

The tyre pressure monitor from abs wheel speed is rubbish

should be like Renault and show exact pressures…

[CJJE]

From memory, it's available as an option if you require that. But my only experience with the Renault system was in a hire car in Corsica... when it would light up like a Christmas tree when one side of the car was bathed in sunlight!

mine is a new all options karoq.....and dont remember anyone offering that

oh well....just not very good

[langers2k]

Should be possible to retrofit it...

If like the Renault system then it is expensive when sensors go wrong and need replaced.

Just checked the latest UK brochure, and you're correct it's not shown there. Skoda just provide the legally required version. But there are add-on ones from Michelin etc who fit special valve caps with pressure sensors and a display panel in the car. I've always found the ABS -based system adequate and am wary about the extra sensitivity of direct pressure reading systems.

A genuine VAG TPMS sensor can be had for sub £20 but obviously you will probably need to pay a tyre fitter to install it.

 

Still, compared to most things that can go wrong on a car, it feels pretty cheap to me

[Ootohere]

I was commenting on Renault ones that the OP mentioned.

Really i do not know what they currently cost.

 

If VW Group ones are 'Much cheapness' that that is fantastic.

As it is anyone getting individual tyre pressure warnings should really check each tyres pressure before just going with the one that is throwing a warning.

It is good even when no warning that the pressures are checked and not just via the dash.

Same here.  It's not as if we're F1 drivers where a fraction of a lb. makes a big difference to tyre and car performance and more importantly stability.  The last thing most road drivers need is complex information flashing up in front of their eyes if there's a serious problem that needs dealing with fairly soon/urgently.

It’s always worked perfectly for me and recently gave timely warning of this.

The ABS based system IMHO is fine, it does what you need, still no excuse not to check your tyre pressures manually, I do most weeks.

As to the rRenault system I had nothing but problems with it on my C5 estate also rubbish on Fords .The battery on both systems fail far to easily also you get electrolytic corrosive around the valve seats causing pressure loss.

Being ABS-based, shouldn't the Karoq tyre pressure monitor be reset while driving? The manual doesn't specify.

No, it should be reset immediately after checking/ resetting  tyre pressures before driving.

What does the ABS-based monitor memorize then, if the car is static at reset time?

[Breezy_Pete]

I think it initiates a short calibration period for the next few minutes of driving. Within that time period it will work out average relative wheel speeds for each wheel, presumably ignoring times when there's steering input. Then it must store these average numbers for future comparison.

Missing word

[Sanqhar]

It stores the tyre diameters relative to the other three wheels/tyres. If then one wheel gets a puncture the diameter (hub to road) becomes smaller, the tyre does more turns than the others and the ABS flags up the discrepancy.

That makes sense, thank you.

Could'nt agree more, Skoda are well behind the times

[FlyingGecko]

While they're at it, lets bring back the guages for oil pressure , oil temperature, coolant temperature, voltmeters...  and maybe an altimeter for good measure.  One can never have too much information to take in.

Renault Laguna.

The four TPMS valves had a coloured rubber band around the stem.

You could not move the valves from their designated rubber band coloured position on the car.

The spare when fitted would show a warning light.

The stems would break.

The batteries went flat.

You couldn't just change the valve stem with the rubber seal, so they would leak from where they fit to wheel.

 

 

 

Peugeot 407.

If you had the pear shaped key fob you couldn't move the valves from the original position on the car, if you knew where that was after you fitted four new tyres at the same time.

The spare when fitted would show a warning.

The stems would break.

The batteries went flat.

You couldn't just change the valve stem with the rubber seal, so they would leak from where they fit to wheel.

The later 407's with the rectangular key fob you could at least move the valves around.

The sensors were set to warn you at 2.0 bar but the normal pressures were 2.6 bar.

So you could drive with the tyres underinflated by 0.5 bar with no warning.

 

When these TPMS valves were £100.00 a piece fitted/programmed when it stopped working people would replace them all with normal valves and turn the TPMS off.

 

If you don't have a spare wheel/tyre and you drive on a flat tyre you can break the TPMS valve inside the wheel/tyre.

 

I would rather have the indirect ABS system and check my tyres and pressures.

 

Thanks, AG Falco

Same situation with Citroen.

 

But you tell people who want to slag Skoda off that lot, they'll not believe you.

[J.R.]

One of the mainstream French vehicles had TPMS valves that set off galvanic corrosion with the wheelrim, cant recall the details but a dive buddy 10 years ago ran a French Kwik-Fit type franchise, he said that it cost over €1K extra, may even have been €1.5K on top of the tyres at every renewal with the cost of parts in France, the manufacturers monopoly and them having to be programmed/coded.

 

Yobbos were spotting the vehicles and giving each wheel a well aimed kick and by consequence a huge kick in the ghoulies to the owner.

[Karock]

The SKoda system is fine, it detected a punctured tyre before I had noticed. Why would anyone want a complicated expensive unreliable system?

 

There are enough complications to fail already on modern cars why add to the list?

Totally agree……..I’ve had this basic system on my VW / Skoda vehicles for 11 years now, always found it more than adequate.

Just goes to show you don’t need a fancy complicated  all singing and dancing, bells and whistles, expensive system to be effective.
