A properly-functioning Mercedes oxygen sensor is essential to your car's performance. The Mercedes O2 sensor detects whether or not your engine is burning fuel and air at the right ratio. If your Mercedes oxygen sensor sends incorrect data, your gas mileage will suffer as will your driveability. So if your mechanic has told you that your Mercedes oxygen sensor needs replacement, or if your car is showing the symptoms of a bad Mercedes oxygen sensor, it's not something you should put off. The good news is that your Mercedes oxygen sensor doesn't have to cost a lot of money. If you want it to, just head to your dealership.
