    Did this today on the 1 series. Thank you for the video and everyone for the comments! Definitely having long enough tools helps and lots of patience. Hoping ebay part lasts more than a few months don’t fancy doing it again😬

    Dan’s tip. I taped the sensor to a hacksaw blade which allowed me to position the new sensor over the socket easily. Was frustrating using screwdrivers and the wire. Pushes in easily if you use some silicon spray first.

    Hey, thanks for posting this, exactly the same fault as I have with no start/stop either. What plug in diagnostics are you using for you laptop ?

      Hey, no problem! I hope you get yours sorted easily 👍
      The diagnostics program is called ISTA/D.

    Hi, great video, can you please put a link to a working free version of the software to download. Also a link to the hardware connector you have used would be very useful. Thanks

      It's been years since I was able to get a copy of the software, I'm sure bmw forums may be able to point you in the right direction. I bought a used genuine item from eBay 👍

      Hi. Unfortunately not no.. it looks easy enough to do but will need to drop the oil so I'll wait until the next service 👍

    Hey I have the error codes 3702 brake vacuum plausibility with the yellow brake warning light and the red stop engine light. Bought 2nd hand sensor from local mini specialist and fitted it in. Warning lights still coming up but i havent cleared the codes via diagnostic tool or will it just reset itself whilst driving. Not sure if the part i installed was faulty or working but initial part that was already on the car had plenty of vacuum pressure in there before i uninstalled it. Any help i would appreciate

      hi what did you end up doing? I have the same fault, did you end up just clearing the codes? thanks

    • @user-pd1je3cp7u
      @user-pd1je3cp7u 9 หลายเดือนก่อน

      @NeroPiXL Hi I ended up replacing the brake Vaccum sensor underneath the brake fluid reservoir, and then cleared the codes using a diagnostic tool, and the problem was solved. Just make sure u get a good quality sensor as i purchased a 2nd hand one initially but failed to work. Luckily, the part had a 30-day warranty so I swapped it for another 2nd hand one, and that one did work 😂😅

    Hi
    Can you please let me know what do you use to read the fault, as I have bought three different code reader for my 320d bmw but none has worked. They only read the engine and chassis data but when I had fault it did not reas. Had to take it to garage to read the fault and fix it.

    Can your car not start because you need steering wheel fluid I have a bmw 328i

    • @Mike_M3
      @Mike_M3  ปีที่แล้ว

      I wouldn't have thought low steering fluid would prevent your car from starting

    Did you have to code this part to your car?

    • @Mike_M3
      @Mike_M3  8 หลายเดือนก่อน +1

      No, just plugged it in and that was it 👍

      @Mike_M3  6 หลายเดือนก่อน

      That's probably the best way to do it... I just didn't want to spend the money 😂
