Technical In City Mode, the light turns red and the steering wheel becomes very hard!

[denizari82]

When City Mode is active, sometimes the steering light turns red and the steering becomes very hard! When I stop the engine and start it again, the problem goes away. Is the source of this problem the "Torque Sensor/Steering Sensor"? Or is it the relays in the circuit under the steering wheel?

Almost certainly cables, battery or alternator, not torque sensor

I replaced the battery, only to find the alternator was weak. Yours is probably the battery, but best to check both.

Tanya batteries are very good. I fitted a Yuasa HSB5012 and have not looked back

This is the equivalent. Price is much the same as when I got mine in 2022. It's better to go bigger with batteries, especially with electric power steering.
