    Hey Guys,

    Whats the best diagnostic software to get at a reasonable price?

    (not £800! thats pretty unreasonable, I can get a car for that!)

    I was looking at the PASoft 1.3 off ebay for £25 with OBD wires from China

    Is this legit? Does it work? Is it easy to use?

    Any advice would be greatly appreciated.

    It's works and is very powerful and good for coding but the diagnostic results are given in hex or decimals which are a PITA to look up.

    I'd look at Inpa. It works over USB with a vagcom lead and you'll be able to connect to most modules on the E39. I have connected to the DME and ABS modules on a E39 with an unmodified lead. You may need a ADS interface to connect to the instrument cluster. For £20 (£10 for the lead and £10 for the BMW 20 pin adapter) it's got to be a good option.

    There should be plenty of information available with a search.

    Thanks for the info!

    I just got the PASoft (ebay 30 mins ago!) but will look at the INPA as well .. I may need it as I have a somewhat complex odometer issue to try and sort out! for £30 all in, I have no worries paying that! ;o)

    Heres what I got:

    NEW BMW Scanner 1.36 1.3.6 OBD2 Diagnostic Tool+PA Soft

    Guys,

    I've been fighting to get PASoft 1.3.6 to work for 2 nights now! ;o|

    I have used 2 laptops one with serial the other with a usb serial, no joy.

    Anyone know if the port baudrate would need to be changed?

    And the error messages device not ready or module not found? what do they mean?

    Anyway if you got this working or can suggest something to assist that would be great!

    PASoft should be better for a IC issue.

    I don't mean to be patronising but are trying to diagnose with the ignititon on?

    I've not used PASoft but I have never had to adjust the baud rate.

    Cheers

    Guys,

    Yes I have Googled and tried all the usual stuff ..

    And turned the ignition on! ;o)

    I suspect it may be my serial to usb jobbie .. apparantly the baud rate has to be close to the 10.4 khz that the car runs on.

    From what I understand, COM ports dafault to 9.6 (9600 baud) and the older ones can be 'adjusted/tuned' by the PASoft software to get to within 1% of the necessary 10.4, but the newer COM ports (usb jobbies!) cant be tuned this way as they dont have the full instruction set.

    Just wondering if a tech wizz has the answer here and will say 'oh yes you can fix it by ...'

    Also, theres a piece of software out there that can test your COM port to see if it can work (presumably at the desired 10.4 rate) .. anyone know where this is.

    I'll have a look later to see what I can dig out. You mentioned that you tried using a real serial port as well?

    I have always used a USB to serial convertor which uses the FTDI chipset. You can use Mprog to fiddle with the settings.

    Ian,

    I have done a lot of research and it 'seems' that the (prolific chip) USB to serial jobbie (bought from Maplin) that I have is somewhat an 'inferior' brand ;o) .. typical really.

    It looks like this
    http://www.mcternan.me.uk/UsbCable/

    The information is sometimes conflicting, but generally the Internet seems to indicate that the prolific chipset only uses the 'standard' baud rates and that the FTDI USB to serial converters can be 'programmed' to almost any baud rate, and that they are, simply, more versatile in general.

    I have seen posts that indicate the prolific USB to serial converter also has issues with other serial devices.

    So .. I'm going to get me a FTDI USB to serial converter and try again! hopefully with better results!

    Thanks for the info and I'll let this post know in as much detail as possible how I do, as this is sure to help someone else out!

    (Oh, the 'real' serial port I tried is from a fairly modern laptop I'm borrowing from work, a Compaq NC6320 with Windows 7 installed. I got a different error message with this laptop, something like module not found or module not responding, actually I think I was closer to cracking the issue with this laptop. While my FTDI converter arrives I will try this laptop again in the next few days to see if it will work)

    Guys,

    I have still had no luck .. but am a persistent fellow!

    I once again played with the Compaq with the built in COM port, it has Windows 7 installed and so I played with all of the compatability modes, to no avail .. it refuses to 'communicate'. The next step would be to install XP on it I suppose.

    Also, the FTDI usb to serial converter arrived. Tried this and now have the doomed 'communication' problem .. this is better than the previous message, the 'hardware not ready' error, I have a few tricks up my sleeve now as this FTDI interface has some advanced COM port features that I am yet to try. Also you can manually set the rate to non-standard rates, so i'm going to try and get it to close to the 10400 bps as I can and see if that helps.

    You know what they say: Persistence lowers the resistence. And I am a firm believer!

    Doing a search for 'FTDI 10400' just gave me a huge boost of confidence. This guy seems to know all about this error and has got it to work. A very interesting read.

    http://www-stud.uni-due.de/~sgchhaus/vagcomen.php

    I will report back.
