    Ok, so now that I have my French degree and have nothing to do but work and pay off debt, I'm going to give my beloved Audi TT some much needed attention.

    I replaced the head gasket last year and drove it about 500 miles before another coolant hose burst last fall, so I really haven't driven it since then.

    Turns out my radiator was clogged, so I replaced that and got a new hose to replace the one that failed.

    It currently starts and runs and holds oil and coolant fine with no leaks in either system.

    The heater core is still bypassed, but I have a new one and plan to replace it over the next couple weeks, provided I can find a way to safely discharge the A/C (car is currently off the road).

    My biggest concern right now is getting the thing to pass inspection, so I've provided an Auto-Scan from VAG-COM below.

    You'll see that one of my ABS sensors is out, my hood was open while doing the scan (as well as the driver's door for the most part).

    The thermostat has been removed to provide proper flushing of all the old coolant/oil that was in the system before, but I have a new one ready to go in and a gallon of fresh G12 along with it.

    I don't have a digital camera, but it's black (raven black?) with a grey leather (torn) interior.

    I bought the car off my cousin Andy in 2009 for $6500, and it'll be paid off next month, so I basically owe nothing on it now. He had it in Florida for a few years with no carport, so my hood is bleached grey (mostly above the motor), and he got into an accident with it and never got it fixed (because he didn't have insurance), so I discovered:


    a broken radiator support:

    a broken bumper cover:

    a few broken wires (probably going to the outside air temp sensor), one of my fat fives is bent (currently riding on straight fat fives, but they need work to look good), and the front right fender is bent up pretty badly:

    [​IMG]


    If you want to see something, let me know and I'll take a pic with my cell phone (only camera I have right now). She's not much to look at from the front.

    Edit: Let me figure out how to post the scan without it all being formatted into one block of text...

    Edit2: Pic or torn leather (not a big deal, I know, but I eventually want to get this fixed or replace the seat). The lever that raises and lowers the seat is also broken.

    Way to go Lite! Looking forward to seeing some pics. LMK when you are doing that Rack...

    lite1979 Printing Shit!

    The 02 heater circuit is likely related to when I replaced the crush washers on the turbo feed and return lines. I somehow managed to stretch the wires going to the front 02 sensor when I was putting everything back together, so I probably stretched the wires too far, opening the circuit. Hopefully it's something I can fix easily without replacing the entire 02 or part of the harness.

    When I did those crush washers, I had to remove the three bolts that hold the turbo to the manifold and the three nuts that connect the turbo to the downpipe, but I re-used them to make it to my Dad's car show in Syracuse last year. I have new turbo-to-manifold bolts and a new gasket to go between them as well as three new nuts and a new gasket for the turbo-to-downpipe interface. Should I just try fixing the circuit for now and worry about possible exhaust leaks later?

    Thanks! To share with everybody, now: the steering rack leaks about a pint of fluid every six months from the passenger's side (boot was torn, probably got the rack contaminated with salt and dirt, etc). I have a new rack ready to go in sitting in my Dad's barn (along with the bent set of fat fives).


    I also think a lot of the scan's codes are related to having a low battery, which I will replace once I can put her on the road again and drive her every day. I'm thinking the after-run coolant pump is a large part of the drain, but anyone with prior experience can feel free to chime in there.

    airbags been replaced after the accident?

    lite1979 Printing Shit!

    Nothing was replaced after the accident (sad face). The airbag code didn't show up until after owning it and driving it for six months, though. I've always though it was due to something being stuck under the seat and pulling on the yellow wire, making resistance too high on that circuit.

    A bit off topic but why were you taking a physics lab if you were getting a French degree?

    He was going for engineering at one point I believe. He was in my linear algebra class, another thing that has little to do with french.

    lite1979 Printing Shit!

    UB basically told me that I'd never be an engineer after my first semester back (I wish they had told me that during the re-admission process), so I made the most of it and got a French degree. I took Linear Algebra to replace on of the Fs I got back in 2002, but I didn't have enough math for a minor and it didn't help my French degree at all, so I stopped doing the homework. It sucks being punished for grades you got ten years ago, but that's all I'll tell of my sob story. I'd still like to get an engineering degree, since the math and science weren't that hard, but next time around I'll make sure not to be cooking 30 hours a week (it also didn't help that UB discontinued my financial aid). On a bright note, the Romance Language department's advising staff were more helpful in the first five minutes than the engineering advisors were in five years.


    Back on topic: my damn headliner has decided to sag like a pair of eighty-year-old mammaries. How do I fix this on the TT? It's bad enough that it's 100 degrees in there with the windows down, but having that thing in face when I'm trying to scan codes just adds insult to injury.

    THAT is AN ABSOLUTE NIGHTMARE lol good luck with this bro. I would start with the power supply though.

    Thanks, I'll need it. Small step today: let her warm up to 190-215 whatever marks the "middle" of the temp gauge, and the main fan did in fact turn on, keeping her right at the middle. I still haven't put the t-stat in, so it took about 15-20 minutes to get to temp...

    They sure do! Added a pic to the first post; more to come tomorrow, and I'll be putting in the new thermostat along with some G12/distilled h20. Anyone know how to make the headliner stick back to the top? It decided to fall down over the past few weeks, and it's really annoying sitting in the car with it laying on my head while playing with VAG-COM on my shitty laptop.

    Did the fabric separate from the board or did the entire headliner come down?

    If the fabric separated, you're going to have to reapply it. A light coat of spray adhesive would probably work. For a temp fix, just use some pins.

    If it's the entire piece, I would take it out and reinforce the top side with something. That curved roof is going to make it difficult though.

    The fabric separated. It's still held up around the perimeter, and while I was sitting in it letting the motor idle, I managed to press it and get it to stick for a minute or so, then it dropped back down.

    Sounds like the adhesive is shot. You'll need to take it out to fix it. You'll probably break some trim pieces along the way too.

    Fuck that shit. I'm not pulling it if I can avoid it. There's an aperture where the little tweeters in the roof go that gives me access to the inside of the headliner that should allow me to spray enough adhesive in there not to break anything. I hate having to break stuff in order to fix it.

    Got the new thermostat in with some fresh G12 and distilled water last night. Warmed her up today and she held fine right at temp, them the system burped a little and I got a low coolant warming. Waiting for her to cool down before I add more coolant/h20.

    The battery was dead enough to make the CEL go away, but I was expecting that, as the open circuit 02 sensor heater code doesn't show up until after the car has warmed up once. I imagine it'll come back after I add coolant and she cools down, though. I disconnected and re-connected the harness, but it's somewhat broken, and two of the contacts looked a little rusty, so maybe I got lucky and that's all she needed. That wouldn't be my luck, though. Hopefully I can get a multimeter to troubleshoot which wire is bad or if I have to replace the whole sensor. I must have two or three at my Dad's house, but that's $100 in gas away right now. Any suggestions for a cheap local multimeter purchase?

    Edit: Filled the reservoir with coolant (didn't take much). Started her up, and the CEL is back. Looks like it's not recognizing the front 02 at all:


    From last scan (nothing's changed, really, though I thought the mapped cooling system error would go away. Maybe it's just there from before?
