    Stage 2 Tune made my GTI 1.8T go bonkers! Please help

    Hello to all,

    I am really hoping someone out there might have some knowledge or ideas about what is happening to my car. I've already gotten some pretty decent advice from some 'car minds', but we've still not been able to fix the problem.

    MAIN PROBLEM: CAR RUNS ROUGH BUT DOES NOT TRIGGER AND FAULT CODES WITH STOCK SOFTWARE/ PROGRAM. 3 ATTEMPTS TO RUN 'STAGE 2 SOFTWARE' HAS RESULTED IN CONTINUED FAULT CODES AND LIMP MODE. (please see below)

    2002 VW GTI 1.8T AWP

    Chassis Type: 1J (1J - VW Golf/Bora IV (1998 > 2006))

    Modifications: Stage 2 Tune, cold air intake, 2 or 2.5" down pipe, high flow muffler (I'm sorry I can't remember what model or type), NGK Iridium IX spark plugs

    Both Auto-scan's are the same except for the second fault code in the "Engine" section.

    This is the third ECU/ ECM that we've installed in the last 10 months. The first ecu was a "06A 906 032 HS", the 2nd was "06A 906 032 LP" and the current ecu in the car is a new/ used "06A 906 032 HS" from a nearby auto wrecker.

    The current "06A 906 032 HS" ecu was working decently with an unmolested stock program/ settings. The adaptation went semi smoothly. It was running a little rough, quite a bit of vibrations when idling. None the less it worked for around 3 months without any fault codes or limp mode happening. I decided to be a little over exuberant and put the Stage 2 tune back in. After and hour or two of driving the car with the new stage 2 tune, the EPC & traction control cluster lights came back on and the car went into limp mode. I cleared all the codes and got about 4 days of driving out of it until the car went back into limp mode with the corresponding cluster lights. For some reason this car does not like tunes or the ecu to be tampered with. Is this acceptable or is there a solution to this problem?
    I bought this car with a stage 2 tune and wanted to go fast. Now its broken down
    The only conclusion I can come up with is that the stage 2 tune is running the engine harder/ hotter and in turn the wiring and circuits are heating up causing all sorts of problems.
    Also...before installing the second ECU/ ECM, we installed a new Accelerator Module as the fault code read;17579 - Angle Sensor 2 for Throttle Actuator (G188) Implausible Signal P1171 - 35-10 - - Intermittent. The new Accelerator Module is part# 6Q1 721 503 M. It seems with the new Accelerator Module installed; nothing has changed and the fault code keeps appearing. (keep in mind the above fault codes only appear after installing the stage 2 tune)

    Any help would be more then appreciated. This has been driving me crazy. I've been walking and taking the bus on and off for the last 10 or so months. lol....

    Thanks





    After reverting back to a Stock flash (July 27), 2 days later of driving the car the below fault codes came back. I was under the impression that if you save the stock flash file (which we did) and revert back to stock, that the car's ecu is wiped clean and the cars ecu is stock. Maybe not the case?

    thanks.

    Hey sorry was really having a hard time getting that ZPM installed to get back here.........

    Okay

    1 Fault Found:
    17579 - Angle Sensor 2 for Throttle Actuator (G188) Implausible Signal
    P1171 - 35-10 - - Intermittent
    Readiness: 0000 1001


    Lets define what this is in WD first G188 you have it right?

    If you unplug the OXS sensors does this error go away?

    Hi Jack,

    Thanks for finding my thread. I don't have WD, how can I get it? I will unplug the OXS when my mechanic is back from holidays. I don't have a hoist and I'm not positive I can get myself under the car. It's slammed with body kit. I will take pictures of the engine bay and post them tonight or tomorrow. Sorry I havn't gotten those up yet.

    Who me I never kid.............

    Have you changed the TV or cleaned it and lubricated it?

    The picture above should suffice.

    No worries on this low-rider.
    You can do all these tests or overlays under the hood/cal area.

    The tracks circled.......... are the ones you must go check.

    Learning notes:

    See current track Icon 186 in pic above? That is a star-gate in WD terms..... as I reference it.
    It brings you to that destination current track when clicking on it in the actual WD........if supported!
    When you get to the new world, it displays the origin current track at bottom of the page of the WD.......... not pictured here.

    Star-gates also existed in Buck Rodgers if you recall.
    The Orb ZPM also allowed for the travel to a far away land........... which the Princess and Commander Kane perused the new world with Buck aboard the destroyer.

    Hi Jack@European_Parts,

    Sorry about the delay.

    Best update I can supply: Mechanic with the shop is gone on holidays until the end of august, Mobile Mechanic is gone until August 07, Tuner friend is gone until August 06.

    It's just me and the car until then. I've been running the car since we flashed it back to stock. All the fault codes came back like I mentioned earlier, but I cleared all the DTC's a week ago and have been driving it. I know it's probably not the best to clear codes and keep driving. But I'm tired of not having use of this car. If anything all the same fault codes will come back in a week, maybe two. It's just a matter of time.

    When our tuner is back this week we will order another used stock ecu from the auto wrecker (3rd one in 1 year!), install it and adapt it to the car. START FRESH, then I will check and clean the TB & TV and lubricate them.

    We will then check, verify and conduct and output test on the wiring (G186, G188 and the rest of them), like you have suggested.

    Will also pull the battery out and check all the ground. (4 I believe there are)

    Wind shield wipers have been permanently off for the warmer months, ecu is easily accessible; I've gotten good at taking the cal off and replacing it hopefully this is the last ecu and time I have to do this. Although we were considering keeping the flashed ecu, re flashing it with stage 2 and having it as a back up for days when the car is mechanically fixed, running up to par and when you wanna go fast....

    Thanks again.

    Hi Jack@European_Parts,

    I have 5 pictures of the engine bay. I'm uncertain how to post url images. I have always just browsed and found them.
