Plugged in my Skoda diagnostic tool which reads (tire pressure warning lower limit exceeded) Can't erase this. Checked tire pressures manually, all read 38psi. I guess the tire guys have upset a sender?

On Superb Mk 2, tyre pressure monitoring is done using abs wheel speed sensors, a lower pressure tyre rotates at different speed to the others as rolling diameter is different. New tyres always trigger the fault for me as the rolling diameter is different to the worn tyres they replaced.

Silly question, have you tried resetting using the normal method by pressing and holding the TPMS button adjacent to the gear stick? That resets any fault light but also starts a new learning cycle where the car monitors wheel speed to determine what the new baseline is for current tyres and pressures.

Thanks for your info. I have tried the TPMS button a few times but the light wont go off. I also had to replace the battery yesterday, so I thought that the diconnection may reset it, but sadly not.

As you say, maybe with more use it may learn the situation and go off. I'm not too worried about it as I know that the tire pressures are ok. I have replaced 3 of the 4 ABS sensors over the last few months, 1 to go.

Once again, I very much appreciate your feedback thanks.

Just checking - did you hold the button down or just press it?

I was thinking exactly the same thing, need to press and hold the TPMS as per my original post. Recall it takes several seconds for an audible feedback to happen (confirming new learning cycle started) and the fault light to go out (if it was on). The only way I could see for the press and hold to not work is if there is another fault active somewhere in the TPMS. Were you using something like VCDS or obdeleven that can interrogate all controllers fully for your scan that just showed the tyre low pressure fault? If that was the case and there were no other faults then the press and hold of TPMS button should definitely clear the fault light even if it then reappears after a short drive. Unless of course there is a problem with the button or it's wiring but that's pretty unlikely.

Did you get chance to try the press and hold reset? Appreciate that you are confident tyre pressures are ok at moment but what happens when you do have a genuine loss of pressure?

Over here you will fail our annual roadworthiness MOT inspection with the TPMS warning light on with a car of this age. I suspect you may have a similar system in NZ so if you are going to just leave the TPMS warning light on, recommend that you check to make sure that this won't cause problems with any such inspection down the line.

Sorry for late reply. I have finally got it off. Yes, we have same situation here, no WOF if a warning light for ABS system is on.

Thanks for your input.

Cheers
