C200K O2 Sensor
My engine light came on a few days ago. I have just bought an OBDII code reader to find the problem and the code it shows is:
"P0134 O2 sensor heater Circuit bank 1 sensor"
I presume it is the sensor before the CAT. The questions are:
how easy is to change? and where the sensor is located? Would this be the right part?
http://cgi.ebay.co.uk/LAMBDA-SENSOR-...item518fbce305
Your help is greatly appreciated.

P0134 = O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
That is the pre cat sensor on the M271 - You can see it from the engine compartment just below the manifold & above the Cat.
That looks like a generic sensor. Buy the Genuine Bosch part number for your car with the correct plug on it. Generics have a bad habit of giving trouble on these cars even if they are Bosch generics
With the correct crows foot 22mm tool it is not too difficult but the sensors can seize in the pipe requiring persuasion (FBH). Fit new sensor with anti seize compound on threads.

Yes - That looks like it. Benz have a number of Part numbers for this. As long as the vendor is being honest that it is genuine Benz rather than a replacement for. It looks right.
