Building your own interface/cable

I have one of these and am very happy with it. However, it doesn't work with v4 of VAG-COM if that's important to you :)

According to his website, he usually desptaches them the Monday after receiving your order...
I emailed after placing my order, and got a prompt reply & delivery too.

Have just ordered the rest of the bits from Maplin, couldn't find enough bits to nick at work :rolleyes:

UPDATE: Just built mine this weekend - and it worked first time.

I'd forgotten which way round LEDs fit - it was 50/50 whether I got them the right way round, but they worked. Shorter leg is the negative side....I think !

Granted, it doesn't look overly pretty, mainly because of my blobby soldering and absence of a case, but it seems to do the job.
Also I had to remove the backshell from the PC-end D-Type, as the one I bought was quite bulky and stopped the connector mating properly to my laptop.

I just need to get the full version of VAG-COM now, the shareware version is a bit limited...

Another update:

After having trouble opening the ABS controller, Uwe from Rosstech notes that some Bosch ABS controllers won't work with v3xx of VAGCOM. They will work with v404.0, but you need a better interface - the self built opto-isolator jobby from Andy Whittaker won't do it.
Seems to open everything else though.

Uwe's response to my ABS query

I don't think you can - read the notes on RossTech's vagcom pages, I'm sure it's discussed there somewhere.
Got a feeling you have to use PCMCIA ?

Maybe it will work, I was just quoting from this page on RossTech's site:
If you have a newer laptop which doesn't have a Serial Port, then you must get a USB interface. Add-on USB<->Serial Converters are not supported! USB interfaces require Windows 98, ME, 2000 or XP. They will not work with Windows 95 or NT4! USB interfaces work best with Windows XP.

Hi Mexicupra
Perhaps you could ask this in a new thread, this thread is to discuss interfaces & cables...(but maybe you should check out the Rosstech site first to see what vag-com is ;) )

Ok, sorry if this has been asked already but I couldnt find the answer. Can I use my SPS1 dongle with VAG COM? As you know the SPS1 switch has a round female conector on the back of it. Can I use an ordinary serial cable and cut the "big" side off and connect it to a male conector so it fits the SPS1 switch??? If yes, which pins do I connect?

I hope I am making sense...
