What's the mercedes fault code 7266?

Mercedes fault code 7266 means that there is a problem with the steering angle sensor. The steering angle sensor is in charge of making sure that the wheels are aligned and straight on the car. If it is not working then You will notice that the car has a wobbly steering wheel. This will also give You delayed turning time when You use the wheel. Due to these issues, it is dangerous to drive like this, so You should take it into a shop and have it fixed right away. A new sensor will cost You about 400 dollars, so not cheap, but a lot better than getting into a wreck.
