ABS traction control run-flat indication

Do you have any insight on the reason these warning lights are illuminated? I have verified in engineer mode that all wheel sensors are functioning properly. I have inspected the sensors for contamination, and my brake fluid level is OK. I have attempted to use two ODB readers, but neither has detected a problem code.
2014 W204 C220.
Thank you in advance.

What are the tyre pressures?

If it resembles the 211 brake light switch, it is advisable to get expert advice to avoid the potential pitfalls of incorrect components selection.

Are all tires exhibiting comparable wear, namely none being new (fewer than all four tyres)? It is probable that the brake switch is the issue. The dashboard lights likely activate just upon engaging the brake pedal, but not prior to that action. Ignore the functionality of the brake lights; these switches often include a pair of connections for distinct functions.

I would examine the error codes using Xentry; the issue is likely related to the wheel speed sensors.
