I'm looking for the pointout of the AMI connection, so I can make sure a BT adapter there is hooked up to ACC power and not constant battery power. All I find on the web are the iPod connections form adapters, nothing on the AMI pinout itself, nothing to tell me if there even is an ACC power connection rather than BAT.

Anyone able to help with the pinout for the AMI connection itself?

Warhead

Not sure if this is what your looking for. I happen to come across the in my search.

Redd

Thanks, Warhead. That's a good start, but it doesn't get specific enough, i.e. which leads are battery positive, accessory positive, AMI-controlled, AMI-sense, etc. I need to know which pins on the AMI socket itself, are connected to which power (and signal) lines.

Anything else that perhaps was following that diagram? Or a source?

And then I'll just need to explore how that socket comes out of the glove box. (Any idea?)

@redd. the connector pin numbers are listed above the R199 connector
all the digrams are in the erwin files. I paid for one day access and d/l all files i need

Redd

Thanks, Wani. My main problem with Erwin is that I usually can't figure out where they'd hidden things. I think I was out sick, that week in grade school when they were teaching everyone to use telepathic German indexing conventions.(G)

Warhead

lol, yeah I downloaded it as well, but it isn't very clear on what signal is at what wire. sadly this is far as I got with the Erwin stuff.

Redd

I'm convinced that Erwin is a marketing exercise, designed to make non-Audi shops say "We charge extra for foreign cars."

I've seen and used CAD systems. And publishing systems. And Erwin? Smacks of the 1980's. I'll have to go spend some quality time trying to coax the AMI socket out of the glove box, to see if I can access the wiring behind it. Or maybe just attack the iPod adapter that came with the car, to see what power leads I can find in that side. Folks who stonewall just motivate me.(G)

First, you need to use the correct DIN release keys (see the little slots on the bottom corners of the AMI unit). The keys are a certain configuration. You can try a piece of stiff wire instead of the keys but you could damage the AMI release pins to where you will never remove the AMI unit.

Second, the ERWIN wiring system is very easy to use if you know how. I have been reading these wiring diagrams since I owned my 1987 VW Golf, they really don't look any different in 2017.

Also you need the VAG VAS 5054A tester, this has on screen step by step troubleshooting which includes telling you what to expect to see at each connector pin.

Thus for some of us hard core DIY Audi owners you need to own your own set of Ross-Tech VCDS, VAG VAS 5054A system and VAG ERWIN (ElsaWin 5.2/5.3).

If I have time later tonight I will look at the AMI wiring diagrams.

EDIT...........


Took about 10 -15 seconds to find it on ERWIN........

Outstanding, Bob!

I did see those slots and the DIN bars came to mind. What are these special tools shaped like? Hooked ends? Or just tabs? If they're like radio removal tools, I can cut those from an old credit card.

The pinouts don't seem to mention anything as simple as BAT and ACC voltage, it looks like the AMI system makes power decisions based on how the device identifies itself, i.e. from the drop resistor used for the purpose?

What does "CVBS" mean??

Posted elsewhere: I found they had given me a BT adapter, not just an "iPod cable" with the car. Sadly, an unbranded $10 "I-Link" adapter that needs an I-thing 4, not later, apparently since my AMI system won't initialize it.

You get karma points for this one! Erwin and I, we just speak different languages.

Bob Petruska

CVBS means either - "Central Valley Birding Symposium" or Colour Video Blanking Sync, Colour Video Blanking Syncs, Composite Video Broadcast Signal

On the keys........I own these and I believe that is the narrow pointed one on the right works for the AMI.

The easiest way to find your voltage answer is to pull the 12 pin connector and measure each pin, just a warning to be very careful as some of these pins are connected to the fragile CAN BUS, you don't want to short any of those pins to ground or you can fry some expensive module(s).

What are you trying to do????
