    I have got an error indicating:

    Error: O2 Sensor circuit slow response Bank 1 Sensor 1 (Upstream / Pre-cat) signal rate of change below threshold.

    Anyone able to assist me with getting the Mercedes / Bosch part number please?

    Vehicle details: 2011 E200 CDI (no stop / start)

    Chassis number: WDD2120052A415442

    Engine: OM 651

    Any assistance / guidance highly appreciated.

    That is extremely helpful. I am ever so grateful.

    Any chance you might have some insight into details of location of said pre-cat / upstream O2 sensor? DIY to replace?

    Thanks again for the diagram. In term of location, is this situation on the about lower middle of the drivers side (near to the front off-side wheel)?

    Thanks to your help, I managed to order the needed Bosch part from eBay for £70. Mercedes were all to happy to sell the same part to me for £266.40! And of course, they would strictly not give me the part number.

    Would love to know how one can obtain a reference source of part numbers for my car.
