    Question What diagnostics cable & software for BMW 2.5 TD 1995

    Hello all

    I'm looking to buy a diagnostic device to plug into the 20 pin socket under the bonnet.

    There is no OBD1 / 2 socket in the car as it it PRE 1996.

    However I can buy an adapter - 16 pin OBD2 to 20 pin BMW.

    1) Which would allow me to connect the OBD2 end to a OBD2 handheld device.

    2) Alternatively I could connect the OBD2 cable end to a VAG com type cable with the USB on it, so I could plug the usb into a laptop & the 20 pin end into the BMW.

    Or buy a kit as follows:

    I know the VAG com cable is for the volks/audi/seat groups, but if i linked it to the 20 pin bmw cable & had the right software I'm sure it would work.

    I presume its the diagnostic SOFTWARE on the disc that gets the cable working etc.

    I look forward to any replies.

    There's no 16-pin socket because the car is pre-2004.
    Diesels in Europe only had to comply to EOBD starting at 1st. January 2004.
    You'll need something like Carsoft for this one.

    I already know there's no 16 pin plug in the car as my opening thread post states.

    Please read the post properly.

    Unfortunately the ONLY thing that will work with 100% sertanty on your car is a CarSoft 6.5 (or newer) kit. This is the same tool BMW mechanincs use.

    For a long time CarSoft only used serial connection, and where quite pickey on the USB->Serial adapters.

    Have you read my post? Especially the last word of the 1st sentence?
    Have you read the 3rd line? I know that's not what you want to hear, but that's how it is.

    You have had a similar answer on another forum. Now you can ask the question on 10 more forums, the answer is still the same.
    You need BMW-specific software. There's no cheap solution.

    ^^ As I said earlier... The only thing that will work for reading fault codes and resetting them is original software and equipment.

    Though. I do know of people that have been able to use "taiwan special" hardware, but the still needed to use CarSoft's software.

    Did somebody try revers protocol(s) on BMW ?
    Why there is no cheaper solution ? Is there some type of crypting ?

    What about BMW & MINI DIS (v57) SSS (v32) and BMW TIS (v8) someone suggested this would work or cover the car I want to use it on.

    I have heard of people buying the VAG cable (see pic in 1st post) then connecting it to the BMW cable (see pic 1st post) - so you have a USB connector one end & 20 pin socket the other.

    You connect the VAG OBDII cable male end to the BMW adaptor OBDII female socket.

    Basically you link the 2 cables together.

    Then via the above software DIS v57 or the carsoft 6.5 software you can access the car.

    Yes, I reversed engineered the BMW protocols for several manufacturers of aftermarket scanners. But that is an entirely different price class - a lot more expensive than Carsoft.
    You can buy Carsoft for a few hunderd euro. Professional aftermarket scanners are several thousand.

    Easiest and most cost-effective route is the FCX3 (http://www.ukobd.co.uk/shop/12-bmw-t...rch-fcx-3.html) which plugs straight into the port.
