No fault code found.

Could it be that the voltage is too low, and that is causing misfires? I can't fathom what else it could be; I changed out all four coilpacks about 2,000-2,500mi ago, and new plugs about 1,500mi ago (NGK BKR7Es). Changed the ground cable on the battery and that seemed to help for a while, now it's bitchin' again. I'm am thinkin' I need to check the rest of the grounds as well (the battery isn't 3mos old).

By the way, engine is ATC code from a 2000 Audi TTQ 180 and is chipped with APR software.

Thanks in advance.

That would be the first thing I would do.

No Im j/k, Start by clearing all the codes as has been mentioned and from there see which come back first. This will make it less overwhelming.

I didnt read who this was, SAVE THE MARSHMALLOW!!!!!

lol how do u have a VRT and only 58 posts, that is awsome btw

How do you have spongebob squarepants ants in the pants and I cant buy a chessboard. - Me in Walmart

keep fighting the good fight alex. SAVE MARSHMALLOW!

Yes, I have no idea about them, point and laugh if you must. I have a bentley so I know where they are, I just need to take some time to dig in there and figure out what is what. I probably need a multimeter to check them as well right?

Marshmallow can closely be translated to = pain in the ***

This leads me to believe that it's been the relay causing me voltage issues (i need to check the rest of my grounds as well though). I think the O2 sensors are a result of the misfires (exhaust reeked of unburnt gas). Hopefully she just needs a few more ground points...

don't worry about the misfire codes

sounds like your wideband (Front) 02 sensor is shot (is it new?)

you have 2 knock sensors (did you install these?) they might just be too tight?

all the throttle/boost sensor/electrical issues are usually from a bad battery...the manual specifies 11.5V or higher and they aren't joking I am not counting out that it can be the main relay, but I will guess that it's the battery...

Ask me how I know that you get all kinds of codes when one of them isn't connected or is connect intermittently.

If it's actually running ok, then that probably isn't the problem.

My next guess would be the fuel pump relay. Yes it can go bad and throw a TON of codes. Or the main power relay. They aren't terribly expensive. I think I have a good extra one sitting here, but you probably wouldn't want to wait for it to get there.

Yep, cleaned the terminals not 2 weeks ago when I plugged stuff back in.

I noticed that the battery ground was pretty corroded, so I took a wire brush to it and some petrolum jelly and installed my new battery cable and that seemed to help (it had cold start issues (engine would sputter forever until it was fully warmed up)). New programming seems to have helped that a bit though.

I will go check the grounds first, then climb under the dash to get to the relays. Thanks for all the help you folks have offered so far.

Battery isn't more than a month old, which is why I am starting to lean towards the relay.

Checked the grounds near the ECU: There's only one... Only post with anything bolted to it was the one right in front of the ECU; it had three ground wires bolted to it and was fine. The second had nothing bolted to it, as well as no apparent cables that needed to be grounded.

So I move on to getting to the relays. Then I find this...

These are after only removing the windshield wiper relay and the fuel pump relay to get a better view.

Am I wrong, or am I missing like 8 relays?

Also, what are relays that are in the engine bay to? Bentley doesn't tell me apparently...

-Rear lid Remote unlock motor relay (79, position 2)
and
-Power supply (terminal 30b, B+) (109, position 12)

^that's the one I am really wondering about; think it could cause low voltage?

So, is the "main" relay under the hood in the little box next to the brake booster? I opened it up and it had 3 relays it and 5 empty fuse slots.

yep what? Yes those are the main relays, or yes the missing relay could be causing my problem?

so.... so so true...

i also have misfire problems...wtf

Start he up after her wash; BAM!!! Starts sputtering again, white exhaust again (smells rich...again), and there is ZERO low end power and surging like you wouldn't believe; I mean I have my foot as still as a statue on the pedal and it will feels as though it gives giving boost, taking boost, giving boost, taking boost, etc.

These are the codes I just pulled up.

Any new ideas?!? I NEED to get this thing fixed it is my only set of wheels (and I am tired of bribing friends to drive me around).

I am thinking:

New 02 sensors

Also, does the CD version of the Bentley tell you how to solve the problems? My paper version does do **** when it comes to explaining how to fix codes...

I'd sure appreciate any help you folks can offer.

ughhhhhh i hate cars sometimes

I'll try and check to see if these sensors that are bugging out happen to branch off of something together and try and track it down that way.

Somebody up in the PNW, remind me to thank the guy that sold this to me...

at least oyu have obdII and it tells you which sensorts are not working correctly... it just seems like whatever is shorting outis taking a bunch of sensors with it so thta might not help at all...

here what i would do... even if you end up finding nothing at least you can clean some stuff up. remove your battery, start pulling plugs from different places and trace the wires back ot the harness and check them out. especially look on the ones on the front of the engine since they get covered with junk and start to dry rot and stuff... open up the plastic cover that runs down the firewall and down to the battery area. pull the harness out of there and just start studying the wires. you might as well go ahead and pull the plugs form the ECU itself and check them over and everything as well

its in there somewhere

Tell me about it; next person that tells me "you got such a good deal on it" is getting a punch to the face.

i thought i got a good deal as well, but along with that deal came a huge hole in the charge pipe... software that doesnt let me drive the car with the MAF plugged in, sport springs that destroyed the shocks in 5000 miles, and an electrical nightmare behind the cheap walmart pioneer headunit.

but rebuilding the engine made it all go away... looks like you didnt get as lucky though

Pretty sure those are copper connections, I didn't notice any rust there.

I also traced back the main relay to the other side of the harness, and I am pretty sure that the O2 sensor is connected via that loom as well.

This confuses me, and I kinda wonder how both looms could fail simultanously; any ideas? Would low voltage cause a relay problem (I guess it could cause the 02 sensor not to heat-up or such).

What are the main solutions to a battery drain? I want to look into this as well, as when I went out to try and start it again it seemed as though there wasn't enough power to start the engine. Also, some corrosion has appeared on the positive terminal again, although I cleaned it but a few weeks ago. What could be the cause of this?

As always, your input is greatly appreciated.
