    All, the bulk of the problems are solved. The driver's side high pressure fuel pump was the root of blowing the fuse and driveability issues. One new fuel pump and one new fuse and much has been...

    I was searching for descriptions for N112, N320, etc as detailed above, to hunt them down for inspection.

    On searching one of them, I ran across an old post from this forum where a Q7 owner was...

    Jeff,

    Here's one for ya....I have not one but two brake bulb test lights that I've been using for 30+ years. Ha! Mine have alligator clips on them, I'll just clip them to crimp-on spade...

    Fuse S13 was blown. Replacement fuse blew immediately on startup. Clearly we have an issue on this circuit.

    The first consumer to act up was the TPMS, then Side Assist. Where are those modules...
  5. 07 Q7 idle and throttle up feels like traction control

    Hello All,

    Q7 shows EPC and 'fishtail' on dash, feels like traction control at idle. The engine won't die at idle, but idles very roughly around 400rpm.....feels like half the engine is disabled....

    Ok, so this gets odder and odder. I stop by the wrecking yard today and pick up an A4 cluster. I don't care about part number, I just wanted a Gen 3 immobilizer I could communicate with. Figured I...

    Martin,

    The car came to me with a dead battery. I drove it for approximately two hours and everything was fine. I'd have to say the VCDS scan represents a clear view of the current condition. ...

    Copy that. Yeah, I went battery disconnected for more than a hour. No change. This car sat outside broken for two years so anything's possible. Cluster repair.

    So if I were to push start this car (it is a stick), would the ECM know to ask the immobilizer to audit the key? Or if I test-wire commanded the starter to run? I'm looking for a way to segregate...

    Jack,

    This car is a touch north of 180k miles.

    Just some further checking:

    Three metal-bodied fuses on CCM check good. Replaced fuses, no change.
    Removed and reseated three connectors on...

    Uwe,

    I have checked fuses and removed and reseated the two instrument cluster connectors to no avail. The cluster failed while driving, and the car ran another 15 minutes without issue. Does the...
  12. 2005 A4 B6 6speed quattro No Dash No Start

    All,

    Just wrapped up a bent valve / stripped timing belt repair on a 1.8t A4 B6 6speed quattro car. Ran fantastic for about two hours, 40mpg on cruise at 60, good power, etc.

    Two things...

    Jack,

    Well, I found what I didn't want to find. The wump-wump I was hearing was half a 1.8 trying to run. All four plugs are sparking. Cylinder compression is #1 100psi, #2 0psi, #3 0psi, #4...
  14. Jack, I have not pulled compression numbers...

    Jack,

    I have not pulled compression numbers yet. In my experience, a tapped valve engine spins over fast and smooth (as it should since it can't make compression). This engine gives a...
  15. A4 B6 2005 Cranks, Good Fuel Pressure, No Start

    I don't know to look at a bad ignition tumbler, chase a wiring issue or replace a bad ECM. Car is a 2005 A4 1.8t quattro 6 speed manual. Cam timing is off one tooth, the guy I got it from thought...

    This car does have a lot of issues, doesn't it?! I'm a retired IMSA/CART/F1 engineer, so none of it intimidates me, just takes time. How does one eat an elephant?.....

    Agreed. Since I've last reached out, I've disconnected the rear air lines from the valve block and the rear stays high. I've attempted to use the rear lower-to-load feature. I believe one or both...

    Frank,

    Let's cross off an obvious thing that frustrated me when first driving my Q7. The car cuts power when the brake pedal is depressed, even ever so slightly. I am a two-foot driver, and this...

    When I hover above, I get no hints pop up. I have a rear ride height issue; I believe the residual pressure valve(s) are not allowing air to escape the rear air springs. When I go in with VCDS to...

    Security Codes

    I'm having trouble getting any diagnostic work done as I can't get past the security code for different modules. Where do I get the security codes for a '07 Q7 4.2?
