RNessa Tire Pressure Sensor Fault

Greetings. The symptoms you describe strongly suggest a faulty tire pressure sensor. It's like a smoke alarm with a low battery, beeping incessantly! Given the car's age and mileage, a depleted sensor battery is indeed a likely culprit. Have you tried checking the air valves for any physical damage or corrosion? And does the error message appear consistently, or intermittently?

Thanks for the quick response. I've visually inspected the air valves and they appear to be in good condition. The error message is consistent - it's always there when the car is running. If it's a sensor battery issue, is replacement the only option?

Since the error is persistent and the air valves look okay, it pretty much confirms a sensor malfunction, most probably the battery. Imagine a light bulb that's burned out. You can jiggle it, clean the contacts, but ultimately, you need a new bulb. I'd suggest visiting a workshop to have the sensors professionally diagnosed and replaced. They can also properly reset the system. It is better to spend a little bit of money than driving around with constant annoying warnings.

Appreciate the advice. I took it to a workshop as suggested. The sensor was indeed faulty due to battery depletion. The replacement, including installation and error reset, cost 280€. Everything is now working as it should.
