Tire pressure sensor issue on CLA

My 2017 Mercedes CLA with a diesel engine shows a low tire pressure warning and an error in the memory. I suspect a sensor battery issue. Has anyone encountered this?

I had a similar problem with my CLA. The error message showed a flat tire and incorrect air pressure. Did you check the tire pressure with a gauge to be sure? It could be a faulty tire pressure sensor.

I checked the tires and inflated them properly, but the error remains. Did you experience the same?

Yes, that's right. The error stayed even after inflating the tires. It probably is a failing sensor. I'd recommend going to a shop to confirm and replace it. The sensor replacement cost me about 280€.

Thanks for the info. It was a sensor issue, and I got it replaced.
