    Hi all,

    I have been a bmw owner for many years, and have been working on cars for more years than I care to remember, and I work in IT and have done for a long time. However, I have not yet combined work and play and joined my car with my computer !

    I have an e39 520iSE Auto, and it has developed a fault of being very sluggish, not pulling etc. I have got the codes from the Instrument Cluster, which show a couple of things, but not very specific. So I thought I would try hooking a pc to the car and see what that can tell me.

    Looking around there seems to be 3 'ways' to go:

    1) Peake tool, or all-in-one specific code reader/resetter - around £100+
    2) INPA EDIABAS BMW Specific (or VAGCOM) cable - around £45+
    3) Generic OBD-II Cable with BMW Adaptor and free/bought software - around £15+

    I like the sound of number 3, mainly because the cable can be used with other (or maybe the same) software on other cars, for example I have a ford mondeo, my dad has a saab 93 etc.

    Where I am finding a problem is the sheer number of people selling cables and software, all with slightly different descriptions, some using different protocols etc.

    I have a copy of INPA, TIS, ETK, CarSoft, and will be looking to get ProScan, and maybe a couple of freeware ones.

    Can anyone please post some active ebay links, or advice on the cable to go for, which will allow me to start in getting some info out of my cars computer?

    Many Thanks

    Andy

    Thankyou for your response, I have looked at the 2 main idiots guides on here, but they both talk about INPA, I was really hoping to go with option 3, or will the cable still work with other cars? This is the problem really, I am unsure of the right cables?

    Knock a 4 of the beginning of the VAGCOM lead price and you are getting somewhere.

    BMW and INPA success E39/E46 onwards

    I see what you mean, not sure where I got that price from !!

    So would I be ok to get this:

    hxxp://www.ebay.co.uk/itm/VAG-COM-USB-KKL-OBD-2-Cable-AUDI-VW-Skoda-Seat-VAG-COM-Diagnostic-tool-/280829757179?pt=UK_Diagnostic_Tools_Equipment&hash =item4162c206fb

    With an adaptor like this:

    hxxp://www.ebay.co.uk/itm/BMW-E30-E34-E36-E39-Z3-X5-20-PIN-OBD-ODB2-16-PIN-DIAGNOSTICS-ADAPTER-CABLE-/290668261628?pt=UK_Diagnostic_Tools_Equipment&hash =item43ad2db0fc

    Or would this be better:

    hxxp://www.ebay.co.uk/itm/Ediabas-INPA-OBDII-Interface-Cable-BMW-E65-E66-E87-/250980774654?pt=UK_Diagnostic_Tools_Equipment&hash =item3a6f9eb2fe

    Definitely the first two. Before you commit to buy, do you have the 20 pin socket under the bonnet and is the L line (pin 15) fitted? How old is the car?

    The car is a 1996, so one of the first e39's. My wife is just out in the car at the minute, but I am expecting her back anytime, so I will have a look, I am sure I have the 20 pin connector, just not sure about pin 15 and if there is a 16 pin connector in the cabin or not.

    It's a 520i so should be the M52 6 pot and so should support single K Line for the DME like my 1998 M52 E36 on TxD2. You probably won't have a 16 pin socket. Don't worry about it, same signals, different shaped connector.

    Because it's an early E39, you can either play safe and get an ADS interface for about £55, which will require a factory fitted serial port on your laptop (IRQ and Hex address become important there), or be the guinea pig and start with the £11 USB + 16-20 pin jobby.

    ok, she is back, just had a look, and pin 15 is NOT wired up.

    Are the first 2 ebay links i posted likely to be the right choices? Id rather not spend £55 to then spend more fixing the problem etc etc

    To be fully clear, I have the following pins wired up:

    1, 4, 7, 12, 14, 16, 18, 19, 20.

    Well I'm learning here. No L Line on a 1996? ADS not needed. VAGCOM that thing and report back!
