Santro Steering Problems

Sounds like you might be on the right track with the steering angle sensor. The symptoms you're describing – increased steering effort and vibrations – are classic signs of a potential issue there. It's like when your computer's mouse cursor starts acting erratically; sometimes it's just a driver issue, other times the sensor itself is wonky. Have you had any recent wheel alignment work done? A misaligned wheel can sometimes throw off the sensor readings. Also, has the car had any work done lately that might have required disconnecting the battery? Sometimes that can affect the sensor's calibration.

Thanks for the quick response! No, I haven't had any wheel alignment done recently, and the battery hasn't been disconnected either. If it is the steering angle sensor, is there anything I can check myself before taking it to a workshop? Or is it something that requires specialized tools and software to diagnose and fix?

Okay, given that you haven't had alignment issues or battery work recently, it does point more towards the sensor itself or its coding. Unfortunately, diagnosing and recalibrating a steering angle sensor usually requires specialized diagnostic equipment and software that most home mechanics wouldn't have. It's a bit like trying to diagnose a complex engine problem without an OBD2 scanner – you might guess, but you won't really know. It's very likely the coding of the sensor is faulty. My advice would be to take it to a trusted workshop. They'll be able to properly diagnose the issue and recalibrate the sensor, or replace it if necessary.

Thanks for the advice! I took it to the workshop, and they confirmed it was indeed the steering angle sensor. They said the coding was faulty. The total repair cost was 195€. Everything is working fine now. Appreciate the help!
