Is it dangerous to drive with this button faulty?

Not directly, but if you can’t reset a resolved warning, it becomes harder to trust the system for genuine future alerts — repair when convenient, and keep checking tyre pressures manually in the meantime.

Can this button be repaired instead of replaced?

For a worn internal contact, replacement is usually more straightforward than attempting a repair.

What is the button made of?

Plastic with an internal electrical switch mechanism.

I ordered a Heater Blower Motor Resistor for a Toyota Avensis. Delivery took eight days from Latvia to Ireland. I installed it, and everything works perfectly. I wish this company success.

No complaints about Evro Trans itself, everything's fine. But the delivery..... It felt like the order was being carried by turtles. 4 days from Riga to Daugavpils. Judging by the tracking, the parcel just sat somewhere behind a shed for 3 days, then they found it and delivered it the next day. I think that's why I won't be ordering there again.

Bought a front fender for my car. I liked it! After payment they sent more than 20 photos of the problem areas, and it was packed very securely - took a while to unwrap.
