Seat Arona Tire Pressure Sensor Issue

Could be a faulty sensor. I had a similar issue with my Arona. The tire pressure warning light kept popping up, even after inflating the tires. Have you checked the air valve? Maybe there's a slow leak causing the pressure drop.

Did you also get a specific error message? I'm getting a 'Tire Pressure Too Low' warning on the dash, plus the error is stored in the system memory. Wondering if it's definitely the sensor or something else related to air pressure.

Yeah, same error message. I tried tire inflation a couple of times, but the warning kept coming back. In my case, it was indeed the sensor. I'd suggest getting it checked out; probably best to visit a workshop to be sure.

Turned out it was a dead sensor battery, just like I thought. Cost me 280€ to get it sorted. At least the tire check is done now.
