    Hi, i need a new front Lambda sensor.
    Searching for the part on the websites (eurocar and Gfs etc).. i can highlight the part that seems to match what i have fitted to my 2011 E220Cdi Blue efficiency, the length and has 5 pins.
    However...... All the 5 pin sensors say not for the use with stop/start. (The ones for stop/start seem to have 6 pins)
    As mentioned above mine is fitted with a 5 pin sensor...!
    But I HAVE stop/start.!!. :-0

    I dont believe the sensor has been replaced before..
    So i am quite confused to which sensor to buy.
    Or what the difference would be with the 6 pin sensor for stop/start models..

    Any advise greatly appreciated.
    Many thanks
    John

    Don't buy O2 sensors from ECP or other cheapo suppliers.

    I just fitted a Bosch lambda for £75 , MB quoted me £224 (maybe without VAT as well :shock:) . The sensor I removed showed the MB part number and the Bosch number on it as well . I spent hours trying to find the right sensor for my car before I removed it and read the numbers , no one could agree which part was right for my car . In hindsight I would have bourght both recommended Bosch options and returned the one that didn't match the old one , or remove the part (unless you can read the numbers on it whilst in situ) and then order the correct one and wait two days for delivery .
