Well i should have known not to mess with this but i ordered one of those 30dollar modules off ebay to see if it actually worked, i firgured id give it a shot and it arrived within a couple of days.. so i grabbed the instructions and put it in as they said. The car ran for a little bit but didnt do anything, i reverse the setup cause they said if it didnt work to reverse it and reset it.. i turn the key and its just turning over.. i just get rid of the module completely, bringing it back tot he stock setup and same thing.. every once in a while it tries to start.. and if i pull the intake tube off of the little black piece on the engine that it connects too and spray starting fluid in there it sputters a little.. so i know im getting spark. i checked my fuel line and its plenty of pressure and gas and whatnot.. so im thinking one of my air valves isnt working.. but then why is it trying and sputtering a little bit with starting fluid or if i try it a bunch every once in a while it sputters a little but no starting.. its a 2.8L BTW.. I have been working with cars for a while but im kinda stumped on this one.. I read somewhere the IAC valve might have something to do with it but i dont really know.. they looked pretty pricey as well..
Let me know if you have any ideas because i sure dont
and i dont really want to take it too a mechanic but if i have too i guess i will.. or get it towed there anyway
Thanks

UMM, you not giving any good information.
First off what module are you talking about?
Second, the very first thing you do when diagnosing a car is pull the fault codes, what are they?
and fault codes, im guessing thats the diagnostic machine or something?? i dont have or know how to get those..

Yeah f(ck that thing, don't go cheap on something as important as engine mangement.
For fault codes go to autozone and they will pull the codes for you for free, post what the code is here and we can tell you what you need to do. A code will look like this "P0320"
If you want to get your own scan tool down load the VAG COM software onto your laptop www.ross-tech.com (http://www.ross-tech.com) and buy a diagnostic cable so you can diagnose everything yourself.

Well since you said it kinda wants to start with starter fluid, the 2.8L engine suffers from carbon build up from using low grade gas all the time.
Take off the intake tube to the throttle body and empty a can of carb clean while somebody is trying to floor the motor and or cranking it.

02-28-2008, 08:54 PM
Sounds like a good plan.. this car was just purchased and im going over it doing some mods to get some more power, i have a K&N genuine cold air intake coming in for it and im getting the exhaust redone, it has always seemed like it has lacked in power for a 2.8L but maybe thats just because im used to my GTI.. but then again my 07xterra beat it in a race so who knows.. i figured it will help but i will check out that throttle body.. the diagnostic cable was ordered so i guess ill just do cleaning things and such for now until that gets here..
If there are any other common problems like that, let me know

I was saying that I once owned two High Performance Roller Skates.
One day I used one to help move a Turbocharged Audi motor across the garage and the roller shake and motor fell in love.
They took off down RT 95.I gave chase with my 200QT but could not keep up.
The last I saw them they were headed south at about 125 MPHand accelerating.
Later I heard rumors that theNY State Police had reported seeing a high speed object flash thru the toll booths at theGeorge Washington Bridgeand the MD State police went on alert because they were concerned about an unidentified high speed object approaching Washington DC.
After that I lost track of it, but believe one can hear it at Seebring lateat night. I thnk it is looking for it'sbrother -an R-10 TDI.

You know now that I think about it, when I was with the hooker, she was on top (of course) and I remember seeing a flash of light fly over her head. I thought it was headlights from an A6 out front. I guess I was sorely, sorely (itching burning and oozingly) mistaken, it was obviously your HPRS....

Google "Tweaked Motorsports" to get information about module altering IAT sensor signal to make engine run rich. However, if you have an 1997A6 2.7L AFC engine, then were is the IAT sensor? If you did't know, then you could have a bad installation. You need to check if it really was the Intake Air Temperature sensor. You may have fouled sparkplugs. You need the Audi shop manual from Bentley, if you damaged the electronics.
Also, expect internet advertisements to be too good to be true!

03-08-2008, 10:40 PM
The 1997 A6 2.8L AFC engine has a coolant temperature sensor and an erg temperature sensor. Therefore, you should try to identify the part you thought was the IAT sensor.

well i ran into that dilemma in installation, so i emailed them and they said the mass airflow sensor, so the metal cylinder on the intake tube.. that brown wire with the red stripe is the culperate with the bright green one.. so i dont know what that could have done??
maybe now that we know it was linked to the mass airflow sensor we can figure more out?? i didnt think to mention that..
haha and yeah after the can didnt run i was curious and opened up the casing and it was indeed just a little diode.. i was kinda pisseed.. they said i can get full refund if i desire so i might be heading that way

03-09-2008, 10:07 AM
For the 1997 A6 2.8L AFC OBDII US & Canada engine, at the MAF sensor the green wire goes to terminal A12 of the ECM, the brown red wire goes to ground at 46, and the black green wire may go to ground at 39. So, the green wire is for the MAF, and this green wire is shielded. The shielding goes to ground at 44. However, the Audi wiring diagrams on the Bentley CD are not always reliable. There may be omissions, small errors, etc.
You may have flooded the engine with fueland fouled the sparkplugs.

so basically i should just replace all the spark plugs?? Im fine with that if thats what you suggest, not expensive to do and they were probably due to be changed anyway..
ill pick some up this week sometime and hoepfully that will solve the problem..
after trying to start it so much then replacing the plugs, is there anything in particular i should do before i try starting it again with new plugs?? should i turn it over a few times with the plugs out to rid of any excess fluids in the cylinders or not??

I just re-read all the posts in this thread and I mentally blocked out the wise ass (AKA fun) posts to see if I could help with the problem. Assuming that the A6 ran OK before the addition and removal of the moduleI would do the simple things first. Remember life is simple - it is people that make it complicated.
1. Make sure the wires are attached correctly. Check the connections. Make sure you didn't mess up a connector.
2. Reinstall the module and see if that helps.
If those don't work , there is a good chance that you fried the ECU or messed up a sensor. Sorry to tell you that but if it was OK before, and bad after plugging and unplugging, and the wires are OK -- something else got messed up.
I don't know what to tell you after that other than invest in a VAGCom so you can diagnose the problemat home. It might not give you the answer but it is better than towing it to Autozone for a feebee scan or a dealer and spending a gazillion dollars or so.

The green MAF wire is surrounded by shielding which is grounded. Did you reconnect the green wire and short it to the shielding? The shieldingis usuallymetal 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., whichcause fouling ofthe plugs.
Take one of the new plugs out to see if it is fouled with oil and carbon. If it is, the plugcan 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 fora newecm, 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 throughthe 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.

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 runningperfect 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..

Go to www.ross-tech.com (http://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 oilpast the worn oil rings, etc. Add too much fuel and the engine won't start.Just clean the carbon off the insulatorby 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 ignitionswitch on, but not in the start position. Checkfor 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 startwithin one minute. You may get better results with a fully charged battery, and by waiting about a day between each attempt for the fuel todissipate.
If this doesn't work after three tries, then check the resistance on thesparkplugwires 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 wiringbetween 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 pinfound 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?? ^^
there we go, maybe when i noticed the chip didnt do anything i just pulled it off without disconnecting the battery.. so it seems like its pretty clear that the ecm is blown, but ill wait for you guys to respond before i order the new one..

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 onits 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 anamphibious 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 inthe 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.

well i was out messing around before i got that last message and i got to the ecm in about 15 minutes.. (i didnt see what was so hard?? it was like 4 screws total and a little wiggling and pulling, i discovered 4 fuses there and low and behold there was a 15 amp one that was fried, i put in a new fuse and wamm it starts up... i let it idle for aobut 15-20 minutes and it idled fine with no rough idling or anything then i took it out for a spin with the intake on it.. man did that k&n make a difference..
So i give a great thanks to all of you for all your time and effort.. and it seems a6hcw nailed it at the end there.. i just happened to find that fuse before i saw his message..
you have no idea how happy i am right now lol.. no costs to me other than the little fuse which i have a bunch of those in my garage anyway so im very satisfied.. took it out for a spin and is running great..
i cant believe that i didnt hear of those fuses until i saw them.. youd think theyd be online or in the manual or something??? but whatever im just happy it all worked out..
Thanks again

The 15amp fuse, S103, is for the three ignition coils and the MAF sensor, per the wiring diagram. This fuse may be in the electronic control box under the rug, or hidden somewere else. I had the same problem locating the hidden 60amp fuse for the radiator fans, on a 1996 A6. There are four fuses hidden in the electronic control box under the rug. These omissions in the Bentley CD and the owners manual of the physical location of certain fuses is interesting, as fuses sometimes fail.

yeah, i couldnt believe there were 4 fuses down there.. especially ones as vital as that..Oh well.. im just glad i found them..

The ecm is connected to the black green wire and fuse S103, so that is why the VAG-COM could not communicate with the ecm. Also, the ecm is coded using a VAG-COM, per the Bentley CD.The "Function Chart" on the ross-tech.com web site lists the differences between the shareware and the full registered version. The ballon with coding chart data will only appear on the coding screen, if the VAG-COM is registered and actvated. Click on the underlined "YES". Also, without the Bentley CD,it will be difficult to use the VAG-COM without making a few errors. You can get the CD at www.themotorbookstore.com (http://www.themotorbookstore.com)or from www.bentleypublishers.com (http://www.bentleypublishers.com).
