Dear Skoda community,

I bought a second hand Skoda Karoq 2022 last year and I am absolutely in love with the car and the Skoda community. Overall, the car I bought was in very good condition and had no scratches or other visible damages. However, shortly after I purchased my Karoq I got an indication that one of the tyres had low pressure and when I got to the mechanic it turned out that a small rock had pierced the tyre. I am 99.9% certain that the tyre was already pierced when I purchased the car and the seller (a large car dealership in my country) did not disclose this. I wanted to ask the community here if it is possible to check the historical tyre pressures in my Skoda Karoq and if so how, so that I can prove to the seller that this was a known issue (and also saving the cost of having to buy a new tyre).

No, tyre pressures aren't actually measured via sensors. The system simply uses the ABS sensors to measure wheel rotation, which changes if a tyre loses pressure. So I'm afraid you'll have to take this one on the chin.

Thank you for the reply Rbz5416. I suspected that this was a long shot, but thank you nevertheless for the quick reply.

Some Skoda models do have direct TPMS as an cost option - but, AFAIK, the majority use the indirect system via the ABS sensors.

Reading the OBD system data may reveal historical DTCs regarding tyre pressure loss, it wont show pressures, but might show a series of events for the affected tyre.

The ABS sensor system can take a while to report an issue if it’s a slow puncture. I’ve had a TPMS alert, pumped the tyre up and continued driving for 5 hours until

I could get the puncture fixed, without a further alert.

I've had more than a few slow punctures due to nails and screws picked up in treads - typically, my Octavia indirect TPMS does not flag until pressure loss is approx. 0.5 bar (normally run 2.6 fronts, 2.8 rear)

thamestrader - I've got a slow puncture at the moment in my MY2019 1.0 SETech Karoq. The alert first appeared with a ping when I was driving a few weeks ago and found the LH front tyre pressure was about 5lbs down. I wondered why the economy had worsened just a little. However subsequently, that main alert warning only appears when first starting the engine and then goes away. There is then a small amber reminder warning signal (shape of tyre cross section) on all the time when driving. That's until I (slightly over) pump up the tyre and reset the TPMS (dead easy menu, even for a non techie like me) and the main alert and amber reminder warning doesn't then reappear for another 10 days or so. However, must get that puncture sorted ASAP.

Did the wrnings indicate which tyre had the pressure loss? I did on my Karoq while I was in Austria. My other car, non VAG, also has TPMS but does not indicate which tyre. Shame, because it should, in theory, be easy to code the TPMS to do this and is extremely helpful.

The visual warning in the instrument cluster should initially display text (with chime) for which wheel is detected - this text disappears after a few seconds, leaving only the general TPMS warning.

The actual wheel affected is stored in the information when the data is interrogated via the infotainment system.

Yes, the warning does say which tyre is the problem

Interesting or maybe not?

When I had the shock absorbers changed to Koni Special Actives 7 weeks ago, I got the garage to swap the wheels around front to back & vica-versa. Previous to this the slow puncture in the front left hand tyre would trigger the dashboard warning every 10-14 days. This wheel got moved to the rear LHS and it is only now after 7 weeks that the tyre has become sufficiently deflated to trigger the warning again.

Just shows how much harder front tyres work on front wheel drive cars than do rear tyres. As I'll be replacing all 4 tyres next spring, I'm now thinking I might get away without getting that slow puncture repaired - pumping up the tyre and resetting the TPMS every 7 weeks is no real hardship.
