How do you check fault codes?

[Kodiak]

This must've been asked before, but I can't find the answer by searching. Sorry if it's an old issue.

So, how do you do it?

Thanks, but I should've mentioned that I have a '96 S6, which I know makes it a bit different. My car has MIL features that aren't implemented on the S2, but that's all I know.

Anyone know the procedure for getting fault codes from and S6 like mine?

Thanks.

You will probably need someone with VAGCOM Diagnostic Software or similar or................go to the Main Stealer who will plug you in and take great delight in charging you a fortune!

Are you in the UK?

The MIL stuff should be there jujst the same sir. S6 or S2 - UK or CA
Aren't the black, white/brown and blue connectors in your fusebox on the S6.

Check sjmautotechnik for any N.Am S6 oddball I'm unaware of. The actual fault codes on the AAN engine are pretty much identical to ABY and ADU...

Okay, thanks. I will give it a go. It's a bit beyond my understanding, but I think I can manage it, once I get my hands on one of those 12v LED dealies.

Time for me to find a non-dealer Quattro specialist in the Toronto area.

Paul, I've just tried to pull the fault codes from my AAN S4 and there is no blue connector, just black and white. Any idea where to connect the -ve of the lamp to?

I've just checked the SJM site and it says the S4/6 AAN uses the engine check warning light to blink out the codes. As usual it's not fitted to UK cars.

Hey, that helps me a bit!

Seems I have to create a short between a couple of terminals under the bonnet to get the dashboard light to blink out the codes. I even have the Audi jumper plug. But what do I do with it exactly? I think I plug it into those terminals under the bonnet for four seconds, then remove it and watch the blinking check engine light. Is that right?

And I do this with the engine running, right?

Will a boost leak produce a code? How 'bout an MAF problem?

[S2central.net]

Kodiak - what you describe sounds right. You do this with the ignition ON. Engine running or not - it doesn't matter. As long as the ECU is powered up it will report fault codes. If no faults found it blinks a special code sequence. With the engine not running you will get a false alarm for the camshaft position sensor (CMP G40) but don't worry about that as long as it goes away with the engine running.

Unfortunately you don't always get fault codes with boost leaks and MAF problems.

JPL - let me look into the 2x2 diagnostic options again. I used to have that on S2 central but removed it as I never encountered an S2 with such an OBD setup - they all have 3x2.....

Gary Bray has a BTDT on the MIL light function.

Click on the S4 piccy and then "Error Codes on Demand"

Thanks, but I figured it out on my own and pulled code 2413 -- mixture adjustment. That seems to confirm my suspicion that I have a boost leak or a dirty/faulty MAF. I hope that's the case, anyway. A quick search on the forum for 2413 revealed a lot of people with my high-load stuttering problem, many of them unable to find solutions.

Thanks Dave, I'd forgotten about the Unicom site.

Cheers,

Why is it that this does not work on my car?

When I put a 12V lamp on the connectors and set the ignition to on, the lamp will light up for 4-5 seconds and then die out. It doesn't even light up very bright, not like 12V bright anyway. The lamp will not light up if I try again, I have to wait for like 5 minutes before I can repeat the 5-seconds-of-barely-light.

The lamp works just fine on other 12V sources, so I don't think it's the problem..

Nothing happens when I try to short the connectors used for activating the fault-reading.

My car is a 1994 RS2 with MTM-chip, it runs like **** and needs to be sorted out

Help anyone??

S6 (at least 96') ECU connector wiring has no blink codes pin.

So the only way (if you are not familiar with soldering iron and ECU wiring) is to use VAG-COM or another diagnostics software which uses K-Line.

How you managed to pull out codes ?

Never mind my problem, looks like i managed to pull the codes.
Problem is.. It was the 4444 code, that means no faults stored right?

That just makes my problems worse..
