Oxygen Sensor error

[Sheldon13]

Hi All

I took my car (2009 E90 320i) on Saturday to get fault codes read and it came up with an oxygen sensor error. We then deleted the fault and read again and it disappeared.

I would just like to know some of the symptoms that come up for a failing sensor and does it need urgent replacement.

The car does feel slightly low on power when warmed up.

Thank
Sheldon

Hi.
My opinion, if it gave a code they might be on their way out.
Replace them if you can.
