    Hi folks :) This fault came up today, with a warning next to it saying "Pending Fault" Does that mean that the sensor hasn't actually gone, but i about to? I cleared it, and it hasn't come back yet after another 5 or 10 miles of driving..

    BMW 3 Series - Tech Talk For All Gen Of 3 Series
    My car was recalled for a cable replacement on the battery and heater. Whilst in the dealer, they offered to replace the timing chain, as a recommendation from BMW, free of charge. Two days after a period of normal running, the car broke down, after poor running. I had to have the car recovered...

  7. O2 sensor surprise!

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    I posted this up on a US BMW forum. However, since doing some more research it seems that UK and Europe might have more relevant information regards post O2 sensors. Maybe somehow I have a Euro spec car that doesn't have post O2 sensors. Here is my original post - E39 Touring 530i M54 motor...

  9. Front and Rear O2 / Lambda sensors - 5 wire

    BMW 3 Series Forum - Technical Talk on the BMW E46
    Do you know if the front and rear O2 sensors are identical apart from the length of the wire on a 2004 E46 petrol? ie can they be interchanged? I am specifically asking about the 5 wire version. I have a spare rear sensor and I intend to fit it to the front (before cat convertor).

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi guys, Posted a thread on here back in March about O2 codes showing when I code read my 530i. I have since changed the pre cat o2 sensors on the car but EML still showing and two codes showing still for o2 sensors (202 lambda control bank 1 control block 203 lambda control bank 2 control...
  12. Lambda sensors suck

    General BMW Discussions
    A few years back one of the four lambda sensors started to sulk about being old. Every so often it would spit its dummy out and throw up the mil. Code reads showed it to be bank B after the cat. For those that dont know, bank a is the first three cylinders manifold, with bank b the rear 3...
  13. Remove oxygen sensor: Hose clip and axle stand method

    BMW Guides and How To's
    I took out a stubborn rusted O2 sensor on my 316i yesterday so I thought I'd pass on how I did it. I could see it was going to be a problem. I could have cut the wires and used a ring spanner and hammer since I was fitting a brand new verified Bosch sensor afterwards. However, in spite of its...

    BMW 5 Series - Tech Talk For All Gen Of 5 Series
    Hi Guys, Bought an awesome E39 530i Auto recently. It's been amazing but the guy I bought it off was selling cheap as the EML was on. I went along with my laptop with INPA and code read before I bought and it was throwing error codes for O2 sensors. I bought it still as it was in great nick...

    BMW 3 Series Forum - Technical Talk on the BMW E46
    Hi All, I have recently changed the cat converter in my 318ci 2004. However the EML light went on again on the dashboard :sarcastic although the emission tests are fine now (earlier on the car was failing CO levels big time). I know the garage did nothing to the adaptations so I used INPA to...

    Imgur: The most awesome images on the Internet See above picture from code reader. Car has misfired cyl 6 before when it was cold. Happened again this morning, assumed it'd be the same cyl, but now cyl4 showed up as a misfire. The coils/plugs are still from factory so I'm assuming they're to...

  20. Where is my o2 sensor? Why does this bms have a different position to mine?

    BMW 3 Series Forum - Technical Talk on the BMW E46
    Hi guys, First question is what is the brown metal pipework doing in the centre of the picture attached labeled dsc_0376 ? Is this there because the EGR valve was removed? Or was it put there as part of lpg system? It doesn't appear in the video I found on youyube below where I was looking for...
