I said wisecracks -- not butt cracks, sidewalk cracks, cracks in the head, or crack cocain and didn't elude to clevage or Maryland crab cakes, so all is OK -- I think! 
mmmmmm crab cakes on clevage

Just what I was thinking of --- Crab cakes on the rocks.
Cleavage = geology and minerals -- the splitting of minerals or rocks along natural planes of weakness determined by their internal crystal lattice. The angle of cleavage is one of the features used to identify minerals.

Are you familiar with the amazingness of the Maryland Crab cake?

Spent a week in the Inner Harbor area of Baltimore a few years back.
All I did was brink beer and eat crab cakes except the night we went to Harbor East and ate Itallian - I mean Italian food.
Good thing I was on an expense account.
dragging out the kids post - In some ways he deserved it -- Putting an E-Bay Performance Module in an Audi is like putting Jessica Simpson in a sack dress. Lots of room to get in trouble!

"Putting an E-Bay Performance Module in an Audi is like putting Jessica Simpson in a sack dress. Lots of room to get in trouble!" you my friend are full of em! That is outstanding!!
Inner Harbor is good times crab cakes and beer thats what maryland does!!!
Next time you make it down to Bal'more bring the Audi we'll do some driving and throw crabcakes at hookers!

Great idea, but my Audi dosen't like hooks of any kind.
Only the best flatbed around for it. (No comments about the flat-bed please.)

fine.... no comments about the flatbed....
we can take mine, the A6 is immune to hooker spit as i have purel dispensers in the car, the washer fluid was replaced with purel as well. No crabcakes though, can't eat crabcakes in the Audi they are meant for throwing... there will be time to eat later, the crab cakes not the hookers

allright got the cable in finally and whatnot, and i finally get it to recognize and everything and when i test engine it comes back as Cannot access controller or a message along those lines.. does that mean ECU?? i didnt know.. after that it would just shut down, no fault codes..
i didnt get the genuine rosstech cables so could that contribute?? i am just using a standard usb interface cable from my autostore that goes into my cars service port..

by the way i grew up in perryhall maryland all my life and we kept our boat on bear creek just off of the chesapeke bay.. we used to go to inner harbour all the time.. so i have had my fair share of blue crabs and crab cakes in my day..

The green MAF wire is surrounded by shielding which is grounded. Did you reconnect the green wire and short it to the shielding? The shielding is usually metal foil or wire braiding, which is grounded to the engine.
Were the sparkplugs you removed dirty, fouled with oil and carbon, or with the smell of fuel? Were the plug electrodes erroded? Did you check your ignition to see if you are getting a spark?
What is the mileage of you 1997 A6? You may have a high mileage engine with worn oil rings, valve stem seals, etc., which cause fouling of the plugs.
Take one of the new plugs out to see if it is fouled with oil and carbon. If it is, the plug can be cleaned off with a spray can of throttlebody cleaner and by scaping. A badly fouled engine is very hard to start in the winter. Don't forget to recharge the battery. If it starts, it must not be stopped until after the engine has heated up and been driven a certain distance.
I don't see how a diode could break the ecm, but if it did, then the dealers want about two thousand for a new ecm, not including labor. You should use the Vag-Com cable with a laptop to see if it gives any code for the MAF sensor. It may be coincidence.
You need to clean the leaves out of the plennum in front of the windshield, by removing the plastic cover. Under the cover there is a drain that gets plugged with leaves, and allows water to rise until it enters through the fresh air vent. Once inside, it goes into the electronic control box, where the ecm gets zapped, because it is under the rug.
I just ran a wire from the ecm to the egr temperature sensor on a 1996 A6 2.8L AFC OBDII US, so you could always have a wiring problem, where a wire broke or shorted out. I took a short piece of brake line with edge ground smooth and pushed it into the grommet on the heater and airconditioning cable on the right side of the car in the plennum. The wire was inserted through the tube, and feed inside to just above the ecm. The tube was retracted from the grommet, then taken to the other end of the wire. The other end passes through a grommeted hole in the plennum firewall into the engine compartment to the egr temp sensor.
This car also had a bad head gasket on the right side, with broken alignment pins. The wire broke when doing the head gaskets. The trunk lock was broken when I bought the car, as was almost everything. The radiator fans were even incorrectly rewired to the ignition switch, and not through the fan relays. The fan relay wires were burnt. Audi hides the radiator fan fuse.
They e-mailed you the wrong instructions. The MAF is not an IAT on your Audi. You don't have a Toyota!
Were are you located. Perhaps the AAA could help you locate a mechanic in your area who could work with you. Perhaps someone in the audiforum lives in your area.

Newest version of software won't work on non-ross cables. Go to ross-tech.com .
Which auto store?

i downloaded the older vversion of vag com and it communicated with the cable and i got results for auto tranny and ac and whatnot.. but when i try to test the engine it pops up as cant process or whatever.. this shielded wire, i understand what you are saying, but what can i do to fix that..
so where is the ecu on my car?? anything i can check on that?? i found a stock ecu for my a6 on ebay for 120.. and i figure i can do it myself.. save myself the 1800..
the plugs were very black, and smelled weird, not really gas but smelled bad.. they had some problems. ill check the new plugs when i get home tonight.. i think the smell was perhaps the burnt started fluid??.. i think the problem is with the fuel injectors, cause it trys to start when starter fluid is sprayed down the intake so that means its getting air and spark but not fuel.. with the engine running perfect before at only 118,000 miles i cant see how all of the sudden it would jsut stop running at all all of the sudden.. ill heck spark again when i get home but im pretty sure its still getting spark..
i live in bradenton florida..

Free Ross-tech software 311.2 is for opto coupled interfaces and 409 for new serial and usb connections.
Make sure you have the correct one.

Go to www.ross-tech.com Click on "Products", then on "VAG-COM", then on "Product Information". Then click on each of the following: "Function Chart", "Interfaces", and "Problems/Issues".
You need to borrow an OBDII scanner from one of your friends, as the shareware is very limited.
The black stuff on the sparkplug insulator conducts, thus causing poor ignition. A high mileage engine may get a lot of oil past the worn oil rings, etc. Add too much fuel and the engine won't start. Just clean the carbon off the insulator by scraping and flushing with a can of throttlebody cleaner for all plugs. Check that the fuel pump can be heard for about one second when turning ignition switch on, but not in the start position. Check for a spark by clamping a sparkplug to a metal part of the engine, which is visible from inside the car. You should see a spark every two revolutions of the crankshaft. You may have to repeat the plug cleaning after each failure to start within one minute. You may get better results with a fully charged battery, and by waiting about a day between each attempt for the fuel to dissipate.
If this doesn't work after three tries, then check the resistance on the sparkplugwires and ignition coil windings with an ohm meter.
Also, try to do the cheapest solutions, before the expensive ones, such as the ecm. Always test a component when possible. Always test the wiring between the ecm and the sensor.

allright, sounds like some good stuff up there.. i get everything besides the last part, as for checking the wiring, what am i checking for?? voltage?? if so which wire do i wanna test??
also may be a dumb question, i couldnt seem to get a clear answer on where the ecm is on the car??

i dont really have any friends at the moment that i can borrow an OBDII scanner from.. Im not sure how much more i can take of waiting for this, i need to get this car running probably within the next week if possible.. Should i just order a new ECM and see if that does it?? ive gone over all the wiring from the mass air flow sensor and it seems to be fine.. i know that its not getting fuel, all i get is some funky smell off of the new sparkplugs and out of the exhaust, along with a little smoke out of the exhaust, which im guessing is oil but who knows?? i really dont understand, when i was testing the module to see if it worked or not i just did a twistt the wires together thing and for some reason i decided to cut all three... after the test run and no change in performance the red with brown and the green with black were awfully close when i got back and could have possibly touched.. would this short something out?? i tried to follow all the wires but they just go into a mass wire cover tube thing (wow lol) and go into the firewall..
I think i need to get a wiring diagram for this thing and just see where all these wires connect.. all my fuses and relays are good so i dont see any of that being a problem..
im gonna try to reset the ecm again over night and try it again tomrrow when i get home..
im at the point now where i will just order whatever i have to.. im pretty much tired of waiting.. id rather try to borrow an obdII or just find out the problem another way rather than pay upwards of 250 just to diagnose it.. thats not really worth it for me..
any ideas let me know

- 2111 (Blink Fault Code), 00513 VAG1551/2 Fault Code Number
RPM sensor (G28)
Open or short circuit, sensor malfunction
Defective sensor & cables, metal fragments on flywheel teeth
Symptom: Engine will not start, misfires, may stop running
NOTE: I have seen this fault code occur after cranking the engine during a no start condition
in a few rare cases where there was nothing wrong with the RPM sensor
- 2112 (Blink Fault Code), 00514 VAG1551/2 Fault Code Number
Timing reference sensor, (G4) (located 62 degrees BTDC)
Sensor malfunction, Flywheel pin damaged/missing, Mis-located Sensor,
distance to flywheel pin greater than 1.2mm (3/64 inch), wiring shielding problem for G4,
hall sensor out of adjustment (3B and early AAN engines only)
Symptom: Engine will not start, possible low power
NOTE: I have seen this fault code occur after cranking the engine during a no start condition
in a few rare cases where there was nothing wrong with the Reference sensor or flywheel pin
found those online.. both sound like possibilities??
i dont know lol.. im just gonna be looking for a while and see what i come up with.. so i will probably have a bunch of little things on here that i will post as i find them..

while that is a mustang, it seems exactly to be my situation.. and the last conclusion is burned ecm..
ill do whatever it takes to fix it myself but let me know if that seems on track or not?? ^^

Audi put the ecm under the rug, were it is impossible to access! You will need to have a dealer parts department look up your ecm number from your VIN number, or use VAG-COM to get it. However, if you had VAG-COM, then you might find it wasn't the ecm! There are hidden screws under the door sill and on the floorwell cover. You will probably need the Bentley CD manual and the VAG-COM to install the ecm, inside the electronic control box.
This may take a very long time, as you may buy the wrong ecm or something else will break. The ecm number is on its cover. How will you know which box is the ecm? There is also another box in the electronic control box. The electronic control box has a two piece cover held by two screws. One of these screws is under the carpet, were a 1/4 inch socket wrench won't fit. Only a ratchet wrench will sometimes work. It depends on the shape and size of the wrench.
Loosely wound connections will cause trouble. You should use crimped connectors with watertight insulation.
How much did the car cost? You need to find somebody near by with VAG-COM, so they can show you how you need it for an Audi, as you also need the repair manual.
Also, you have an AFC engine, not an AAN. The Mustang is Ford. The Rodeo is Isuzu. Each company has different systems. Different Audi's have different ecms.
I am somewhere in Missouri, werever that is. It was in the 70s today again. Maybe it will change its mind and move again to somewhere colder with a foot of snow. What do you use an Audi for in Florida? Now an amphibious Audi would be perfect, so you could go to an island. Of course it would spend most of its time broken with salt water in its ecm.

well the car was 3000, and ive put in a new stereo with subs and kenwood speakers then 18" wheels and now the performance upgrades.. i realize the ford and isuzu are different operating systems but the situation is the same and i would think the outcome would be similar?? with same symptoms and everything i would assume it would be similar and then the fact that the mass air flow sensor goes into the ecm and if the wires shorted out i could have eaily burned something out in it.. im not really worried about getting to the ecm, i realize its alot of work, but i dont think i will have a problem doing it.. i took all that apart when i installed my new radio anyway, i didnt really need too but i did anyway lol. I just didnt know the electronic control box was there.. this is the first problem ive had with the audi and it was at my own fault.. ill do a bit more research but i believe that the ecm is the problem here..

The resistance of the ignition coils is measured to determine whether or not the coil windings are within specification. You need a digital ohm meter. This may also be done on each sparkplug wire. Most digital volt meters are also ohm meters. Weak coils and sparkplug wire will be usually out of specification. Also, these components are easy to test on the 2.8L AFC engine. You can also test the wiring with the ohm meter by putting a probe at each end of the wire. Radio Shack has a lot of items that help connecting the ohm meter probes to a small needle in the end of the ecm cable terminal, A12, for the MAF green wire. The brown red MAF wire should ground to the engine. The black green wire goes to diagram location 39 on the wiring diagram. The symbol is a rectangle with the number 39 inside, connected to the black green wire. so, the black green wire goes to a fuse, S103, which is 15amp, which connects to the main terminal 15. The main terminal is located below the steering wheel, and has studs with nuts. So, you need to locate this fuse, S103.
