Default List of compatible cables (INPA)

Would it of benefit to keep this thread updated with links from ebay and such like?

Ive been looking through the coding section and the question has been asked a number of times but any of the links to ebay items are now dead...

Will any of these work?

Cable in the first link looks like vagcom cable. But costs 10 times as one.
Vagcom cables with ftdi ft232rl chipset are easily modified for bmw use.
Link
And they are cheap as hell.
So first is probably modified vagcom (it works, i know because i use vagcom cable myself).
Other 2 look like chinese knockoff inpa cables. I have no experience with these.

Cable 1 looks like VAGCOM as said, that'll work alright but you can get them cheaper.
Cable 2&3 are fine for INPA too and wont need to be modded.

I have a number of interfaces:
- CarSoft
- VAG COM
- INPA with serial port
- K+D CAN with USB (opaque colour casing)
- ADS/OBD interface

My current favourite is the K+D CAN USB. It works on all current models as well as everything for e46/e39 era. For older cars with the big round diagnostic connector under the bonnet you'll need:
- a proper serial port on your laptop
- a lead with the serial port type connector
USB to serial or PCMCIA will not work for some modules on older cars (fine for newer stuff)

The VAG-COM one you'll need to do some slight modifications for coding & programming but will work for fault code reading unmodified.

With the USB K+ D CAN type cables there are a few installation steps, drivers & a little app that you need to make them work properly. Once you have them they are great though. However a lot of sellers don't mention or probably don't even know what these are. It is a bit confusing trying to get it all to work. I'll try update over the weekend with instructions, pictures, etc. Also with these cables there are two subtle different versions, one with pin 8 enabled, one with it disabled. The one with it disabled is ideal for e90 newer than 03/07 & that era, these leads often come with a black adapter to re-enable the pin 8 (by just tying it to pin 9) so it will also be suitable for e46/e39/e63 etc. The ones with pin 8 active are just older versions of the cable. Worst cast scenario you just need to modify the cable & stuck a switch on it to toggle pin 8 on/off as needed.

The interface I want to get but it's over priced is the www.doitauto.de one, it's a German version of the K+D CAN cable (probably the one that all the Chinese opaque ones have ripped off the design from!). Do not confuse www.doitauto.de with www.doitauto.com they seem to be completely different companies selling completely different interfaces.

I should mention that while a CarSoft interface can be made to work with INPA it is not recommended. When I first got INPA, etc. going I was using my CarSoft interface, you have to run a CarSoft test to "initiate" the lead every time. What a PITA, stay away from this solution! Also not all serial cables will work on ADS cars like e36/e34/e38, the black serial cable below only works on OBD1 cars like pre 2001 e39.

So depending on what car you have that will determine the best choice for you. If it's going to be all newer than e46 then definitely get a K+D CAN one to future proof yourself.
I'll update when I can but I'm just in the middle of some crazy busy work at the moment!

I got one from a lad on bmw5.co.uk. He modifies and sells the cables so that they work with USB. Came with all the instructions and software. It is obd 2 but I was able to pick up a obd 2 - obd 1 cable form ebay for a couple of euro. Works perfectly on my e39, no e30 software though

OK, here are some pictures of the various cables that can be made to work. Just bear in mind folks that the install of all the software is not like buying Microsoft windows where you just throw the disc in the drive & click install.

INPA

INPA is the easiest to get up & running but there are a few things you need to consider when setting it up, there are different protocols for different era of cars, for example:

- ADS is used on e38, e36 & e34, the ones with the round OBC connector under the bonnet. If you set up INPA with the OBD interface set up then you'll have issues trying to diagnose an e36 for example
- OBD is used on e46 & later e39s along with any car of that generation & newer cars use OBD

The complications don't stop there if you plan on using Progman, you need to be worrying about EDIN, OPS & a few other things, but I won't go into that now!

GT-1/Progman

The reason for this is the software (DIS/Progman/NCS, etc.) is designed either for use in the BMW factory or in the BMW dealers, not a general release product. Two of the most basic issues (which have been over come) are:

- GT-1/DIS is designed to run on an IBM T-30 laptop running UNIX with a very specific hardware configuration. Using VMWare gets around a lot of those issues, you're effectively running it as a virtual UNIX machine within your Windows machine.
- GT-1/DIS, etc. is designed to run through a "diagnostic yellow head" (or could be orange too, I'm not going to pretend I know the infinite detail on this). These boxes are essentially a translator that turns (for the want of a better word) the BMW speak into regular computer speak. Some clever people have figured out how to simulate this "diaghead" by using an "emulator" set up. This emulator set up also relies on the virtual network capabilities of VMWare, the emulator can either be on the UNIX side (this is the "FISTER profile" that some of you may have read about on other forua), or it can be on the Windows side (this is the Diaghead emulator). These emulators are used in conjunction with the NetServer that is built into INPA (or more correctly that is built in to EDIABAS). Don't worry so much abotu understanding this, all that you need to know is for running DIS/Progman you need to run IFHSRV32.exe in order for it to work!

OK, on to the cables, there are a couple of protocols that are used on BMWs K & D CAN (there may be L as well but not sure), most of the cables can do the K CAN. K CAN is fine if you have a car built before September 2006, after that you need to look at the list below:

Models that require D-CAN:

- E60, E61 after 3/2007
- E83 after 9/2006
- E81, E87 after 3/2007
- E90, E91, E92, E93 after 3/2007
- E70 (New X5)
- R56 (New Mini)
- And others...

USB v Serial Port
Why would I buy a cable with a serial connector I hear you say? Well if you have an e36 (or early e39 or e38) you will need to use "ADS". ADS only works properly with a real serial port. If you are using a USB to Serial adapter this may not work for all modules in an ADS car. Just be weary of that. So if you have an e36 you're better off with an old laptop with a real Serial port using a serial port cable like this:

Serial Port Cables

1. ADS
As mentioned previously the ADS interface is a different protocol, if you don't have an ADS interface with an e36 then what you'll be able to read with a regular OBD cable is limited. Unfortunately the ADS interface seems to be the hardest to get & most expensive of all the interfaces. Here's a picture of my ADS interface, Do It Auto also do a version of this interface. It works fine on the e36, e39 & e63 (note my e63 is pre-March 2007)from my personal experience.

Suitable for e36, e34, e30



2. Non-ADS Serial port interface
This is a cheap interface & is readily available plus requires no modification. It works just fine on e46/e39 with either the round 20 pin connector under the bonnet or the OBD2 port in the drover's footwell. Set up of this cable is straight forward, no drivers required.



Suitable for: e39 (all), e46 (all), e38, e53.

VAG-Com Cable (modified)
So your laptop doesn't have a serial port & you have a car that was registered between 03/2001 - 09/2006 (give or take), you could go down the route of buying a VAG-COM cable & modifying it slightly. It is not the route I would recommend (I experimented with my own cable & it worked), for a few extra quid you could avoid the hassle. If you are buying one of these cables make sure it has the FT232RL chip in it. There are different chips that work in these VAG-COM cables but for BMW purposes they must have the FL232RL chip in it. You can ask the seller & it will be visible through the blue transparent casing on the connector.
Here's the modification needed to get the VAG-COM cable up & running:

http://forums.bimmerforums.com/forum...t=vag+com+chip

Here's an image of the OBD II Diagnostic USB Cable KKL409.1:



This cable has a built is USB to serial adapter so the disc you get with the cable is usually just the drivers for this adapter. These will have to be installed no matter what car you're planning on diagnosing. Do some further research on the settings required for this cable, you might have to tweak a setting or two.

Here's an image of the wiring modification to get it BMW compatible, circuit diagrams are available in the thread linked above:



Suitable for: 2001-on e39/e46/e53

K+D CAN Interface

OK, this is my current favourite in my cable chest! This does 2001-on cars right up to & including 2011 cars (may be limited by the hookie software for cars after June 2008 on a diminishing basis as the car gets newer). This cable is a USB enabled device, again you will need to install the USB to serial drivers. However you will also need to install the K+D CAN utility, this allows you the ability to switch it from a K CAN device for pre-2007 cars (see list above) to a D CAN cable. There are two versions of this utility, a fancy GUI & a MS DOS one. I find that the MS DOS one works best.

Hera's an image of what this cable looks like:



I mentioned in an earlier post that there is an adapter that is required with this cable if you want to use it on a K CAN car. It re-enables pin 8. The reason they eliminated connectivity to pin 8 in the D CAN is something to do with stability of the Ethernet connection for D CAN. Anyway, the short story is you need one of these adapters:



Some sellers include them in the sale, some don't if you cannot find a seller that includes it you can either buy it separately or simply modify the cable you get with a little switch. What you'll need to do is put a switch between pin 7 & pin 8 of the connector to re-enable pin 8. In the older cables that is all that is done anyway. It might be worth mentioning now that you could be supplied with an old cable (pin 7 & 8 joined together) or the new cable (with nothing connected to pin 8). So common sense tells you that for an older cable you need to break the connection between pin 8 & 9 & put a switch in too.
So pin 8 enabled for 09/2001 - 09/2006 cars, disabled for newer cars, whether you use a switch or an adapter is up to you.

Here is all the installation drivers & information you will need:


Cable installation manual:
http://www.osefactory.com/tools/k+dc...ion_Manual.pdf
And this one is also useful:

http://www.osefactory.com/tools/k+dc...patibility.pdf

The most important bit:

Download the dcan tools.rar file from here:

http://osefactory.com/tools/k+dcan/

This is the K+DCan utility that allows you to toggle between K line & DCAN. Failure to run this correctly will mean that you will not be able to use your cable. Note: you should only have to set this up once for your car & it will remember the setting.
Here is a screen shot of the utility:



There is also a DOS version of the tool above that works equally well.

Interface suitable for: 09/2001 - onwards.

Do it auto Interface

This is identical in operation to the cable above but is appears to be dearer but probably manufactured to a better standard. K + D CAN capable.



Source: http://www.doitauto.de/index.php?lan..._id=179&cat=31

I have no first hand experience with this cable, it just hard to justify with all the other cables I have!
Interface suitable for: 09/2001 - onwards.

Carsoft Interface

This will work for all K CAN (e36, e39, e46, e53, e63), but for God's sake just don't bother!!



Finally here are some helpful websites that will get you on the road to getting set up:

I'm no expert but I have picked up a lot of information in the past while.

Here is a chart that will help understand which connector is needed for what car. Including whether pin 8 needs to be enabled or not.
