apr chipped b7 won't start--in SoCal--need help/vagcom

[gsxtasee]

don't know why.. I was in TX for a week and my buddy used teh car.. called me mid week and said it wouldn't start.. then called back and it was fine. I'm home now and go to leave the house but car won't start.. will chug-a-lug but no start.. like no spark or no fuel or something. I would call Audi Roadside assistance butI don't want to take it in while in chipped mode. how can I unlock the program and turn on teh stock mode (have security lockout and stock and chipped programs).

Any ideas why it won't start, things to try or how to put in stock mode so I can call audi to get the car?

i'm not sure, but you should be able to reflash or reset with key on only? Someone please correct me if i am wrong. You just need power to the ECU, correct?

Have you tried disconnecting the battery for 30s + to reset the system? If not, you might want to give that a try first... Also, when you key-on do you hear the fuel pump prime (you should hear it near the drivers side door) if not, check the fuse...sorry not sure which fuse number it is.

Goodluck homey!

I don't see why they would testdrive your car or anything to see if you're chipped. Can it be the spark plugs? Just read today if all of them go out that your car won't start. It never happened to me yet so I wouldn't know for sure. *knocks on wood

If you switch programs and dont follow the EXACT instructions, your car wont start. It will crank but you'll see some warning lights flash rapidly as its doing so. Did you wait 10 seconds w/ the key in the off position after you changed programs? I recommend you read the manual and make sure you're doing everything exactly as it says.

Can it be the spark plugs?

No, it can't.

The chances of all your plugs shitting the bed simultaneously (let alone on a car that is a 2005.5 or newer) are pretty much zero.

no fuel pump noise and no go after battery unplugged... thanks.. next?

manual? whaat manual? didn't get no manual with APR chip... tried to remember how to change program and figured it out (kinda) but it won't stay in the new mode and I can't remember how to put in the lock out code to unlock it... I remember code but not how to input it.

could someone go over the precess step by step how t ounlock APR chip and then how t ochange modes? maybe the guy who borrowed teh car accidentally fugged with teh cruise control stalk and pissed off the car???

Oh the things you can find on the interweb

Hope this helps!

No fuel pump noise? You should hear a noise when you open the door. I believe on every door open, the fuel pump primes pressure. Try checking the fuel pump fuse? Should probably be a 15 or 20A fuse.

yes and no.. I think my car hates me. I did try searching google for "how to switch APr programs" and stuff like that butnothing good came up.. this is a cool manual (thanks). but I still don't think I did it right.

I put key in and turned on but didn't try to start... had cruise control in on position and entered the number code by pushing up the number of times.. then down to set.. repeat for 4 numbers.. nothing happened.. no EPC blinking.. nothing... hold in set button and check engine light starts blinking 1 and then starts blinking 2 times.. I let of of set button and that's it... turn off car, wait 10=/- seconds.. try to start.. nothing.. no fuel pump sound, nothing but chug-a-lug :(

checked and even switched fuel pump fuse.. nothing wrong with it and nothing changed in car.. still no go..

anybody local to torrance got vagcom?? would rather get this bitch running than wait to call Eurocode in morning then have Audi come get the crappy-piece-o-crap... (j/k, obviously)

[rnp614]

did you press down on the stalk before you started entering the numbers?

[gsxtasee]

did you press down on the stalk before you started entering the numbers?

nope.. should i?

[rnp614]

yes. I think thats what you do before you start inputting the code. Turn Stalk to "on" then one down before you start entering.

[gsxtasee]

tried it and still no go. I don't even think it's locked since I can hold set button and check engine light blinks to go to the progams.. it's not supposed to do that if it's locked.. I seriously think the fuel pump is dead... I will be pissed if that's the case as the car has barely been chipped a little over a month, not driven half that time and only driven "kinda hard' 2-3 times and not all that hard even then... certainly no reason to be killing shit this early on.

I will withold any trash talking, or assumption making until I talk to the shop tomorrow and get their input.. not even going to mention shop name until I get to see what support we have going on, ensure it's not just me being a retarded idiot, or some other such thing... will keep you all posted on the outcome. Not saying it's the shops fault, just saying IF the pump died so quickly, someone should have mentioned the probability of its demise somewhere in the process so I could have avoided the problem by getting pump upgraded if that's what it needs... Either APR or their resellers whould be aware of likely/potential problems wit htheir product and help customers make informed decisions.

this is all presumption until I get more info.. nothing I have said makes any sense, is intelligible in the least, or means anything until I talk to the shop/APR/whomever to get to teh bottom of this!

If your fuel pump is dead, I seriously doubt APR had anything to do with it. Your fuel pump works just as hard with our without the chip.

that's kinda what I was thinking but then after the fact I was pulling fuel pressure codes and THEN was told.. ohh, you prolly need a fuel pump 'cuz the stock unit can't keep up with the chipped boost level fuel requirements if you get on it suddenly without letting it ramp up pressure first.." or something like that...

so, either way like I said---> gonna call shop and see what to do, then take it to Audi and see what to do.. then be really mad at everybody but myself for my modded car breaking down.. it's the American way; isn't it :p

i doubt the chip has anything to do with it, prob something else go to the dealership and call ahead to see if they would be mod friendly. There are a ton of people on this board from socal and im sure they know of good dealerships to go to.

I'm pretty sure your not attempting to set your chip flash correctly, you put the car to the acc position and wait for the check engine light to go out then hold the set button until the correct tune is flashing. It will start off with 1 flash then about a 2 second pause and repeat this a couple of times until it goes into the 2 flashes and a 2 second pause for tune 2. It sounds a lot like you are holding it until the first flash then letting go and trying to push the set button the number of times until the correct flash is highlighted which is not how the system works. Once your in the right tune let off the set button and the check engine will stop flashing then turn the car back to off then back to acc, leave it there about 10 seconds and it should start. There is a chance if you got a full load of programs that your car is on the engine kill chip which is one of the options on the full suite.

[redhott06]

do you have a boost gauge? is it reading 0? my vaccuum hose flew off the other week when i was beating on it and the car wouldnt start with out any vacuum pressure. otherwise...i have no idea..i ziptied that shit back together until i could get a hose clamp! look by your intake manifold and see if there are any lines hanging around..

[yload]

Yeah I had the exact same issue freaked me out, I was 400 miles away from home and was just trying out the chip luckily, I kinda knew how the firmware system worked. But once I got it back to stock I waited to try again. KEY is YOU HAVE TO WAIT 10 seconds in ACC mode prior to starting car no lights should be flashing before you start with new program. Exactly as pakratt99 stated above.

[gsxtasee]

well, the problem is I had a CE light anyway so it would never go off.. got it towed t oPacific Audi (hat that place) and took them a day and a half to pull the codes, they then said there were "too many codes and it overran the OBD tool and they lost all the codes"... they then re-ran it and only found one fault code for teh fuel pressure switch. they R&R'ed teh switch and it seems to be fine now. I am concerned that teh code for low fuel pressure was present and that calls for a TSB t ocheck teh cam wear and the mechanic and service writer were kinda evasive about whteher or not they checked that isue per teh TSB called by the error code I threw... finally teh tech said he checked it so I wrote it down on my paperwork in front of the service writier and went on my merry way. I went back to shop, put it back in chipped mode and will be driving around some tomorrow and will beat on it some to see if it throws more codes but if I'm lucky, it really was just a pressure switch :) we'll see.

thanks for all your help guys. BTWm I only have 91, stock, and security lockout on this car.. it's the wifes car so no 100 octane or crap like that.

I had the same problem. Once you have the desired program flash (1flesh, 2flashes...) let off the set button, turn key to off, with 10 seconds, turn key to acc, wait 10 seconds, turn key to off, wait 10 seconds, crank engine.
