16-pin OBD plug for S2/RS2

[Mr G]

Hi Paul - if you by any chance find a 12th somewhere in your stash, can you I please have it. Else if there are any cancellations please put me in the queue after Henkjan

This one from China for example - Item #: 271081807862

Meantime I shall make up a cable today for a guinea pig to try out before I shoot PMs asking folk for payment.

Thanks

I don't want to split hairs about OBD vs official OBD2 compliance on such early cars as ours but yes the 4-way pinout shown in the 12V link is correct here.

I'm trying to figure out the extent to which the ODB output from our ECU is compliant with the OBDII standard (and therefore what basic information I could hope to be able to retrieve from my 1995 S6 using an OBDII scanner).

I noticed that the pin-out for the ODBII connector (SAE J1962) defines the K and L lines as:

7. K line of ISO 9141-2 and ISO 14230-4
15. L line of ISO 9141-2 and ISO 14230-4

So I suppose the question is, to what extent is our Motronic ECU compatible with those ISO standards? I found a bit more detail on what those standards mean in this pdf:

As an aside, I found a thread which shows that the 1995 A6 2.8 V6 was certified as OBDII compliant (although presumably irrelevant to this topic due to it having a completely different ECU).

The S2 OBD is a subset / precursor to formal OBD2 comms. There are lots of OBD scanners that talk to older VW/Audi machines like ours but they have to support the correct protocols. Some code readers do not support all of the available protocols across the umpteen manufacturers. Try VCDS Lite on your 16-pin plug to make sure you lashed it up right.

The plug itself is pretty simple - K - L, 12V and 0V

They went like hot cakes then

That's them all accounted for… pretty sure I have that 11th but thats the lot - I have a couple more saved specially for project vehicles (sshhh).

Was looking forward to this but as of yet have not been asked for paypal payment or heard anything.Have you completed these?

I have ten female OBD plugs that are surplus to requirements. They have chassis / panel mounting points which make them perfect for the footwell location but you could also install in around glovebox or ashtray area as you wish.

The main advantage of these over the factory 2x2 plugs should be obvious for anyone who has ever needed to plug Vcds or a code reader into their car.

I am happy to sell them for what I paid plus cable and a token amount for wiring them up - they need a special crimp tool that most folk won't have. The raw kits can be found individually on fleabay for 3-4 quid but I am providing a made up cable that just needs wired up to factory loom positions. I will post "how to" instructions here of course. I expect something like 50cm cable length will suffice - anyone can shorten or extend from that.

I expect price to be in region of 8-10 quid including uk delivery but i need to confirm that.

Two of the ten are claimed already as follows -

02 - newsh

Please add your name if interested and they will be allocated on 1st come 1st served basis. I will follow up with PMs for paypal and shipping address etc

I didn't get mine but did any of the above names get their 16-pin OBD plug for S2/RS2 ?????

[S2central.net]

Another thread revival. Sorry I dropped the ball on these. All the parts are still here and nobody is out of pocket.

I will start making them up over course of next week or so and start working thru the list of names who expressed interest. 10 quid each I reckon.

[Henkjan]

if by any chance you make more (or if people drom from the list), I would be happy to buy one

[S2central.net]

I may have a few extras - watch this space I guess !

[dhali7376]

Totally forgot about this .
Still interested when your ready.

I have the first four made today - 10 quid each including UK postage... I have kept the wire tails quite short so everyone can custom fit as they like - no point in me wasting metres of precious cable !

[StickyWickett]

I'd love one of these if you happen to have any left over when you're done.
