I got pretty deep in to the car and didn't find any iPod I'm afraid. Here's some pics to give you an idea. I've done this sort of thing before but I couldn't believe how many sensors and connectors there are in a modern car! Plus those seats weigh a ton! The leak is proving really difficult to find. For now I have put everything back except for the carpet so I can still drive it. It's coming in to the driver footwell somewhere though I know it is not the door window. From reading up online it looks like it is either a sunroof drain or the windscreen seal. I'll be pulling the dash apart soon when I get the chance, I just hope it's not too difficult to find and seal up. It's a real shame! Here's a pic of what I found in the footwell, at least there is a handy well for the water to collect in! I've actually had to use the spare wheel after I got a nail in a tyre. And yes it's certainly a quality spare though a bit scary when it's on the back, had to be really light footed on that journey! If I'm ever up that way I'll definitely give you a shout.

Yes it's strange seeing my car pop up in a forum! I picked it up at an independent garage in Derby, part exchanged a 2010 350Z HR for it. I loved that car but a dodgy knee meant I wanted to go auto. Nearly went for a 370Z but ended up with the G. I get the same questions from people even now and I've still yet to see another G37/Q60 around here. I was lucky that an Infiniti dealer opened just down the road from my house and the car has been faultless. Unfortunately now though it has sprung a leak (of the rain variety) so I've had to remove the carpet. I'm still trying to locate it. But I found a cute little sailing boat under the rear seat - I'm guessing your daughter is too old for that now!

Hey Stan, I don't come on here often but I've just realised from the reg in this picture that I bought this car after you. I thought you might like to know that it's still going strong!

Another G37S here. I too came from a 350Z HR but a bad knee meant I needed an auto and was looking at 370Z's for a while. But then the G37 luxury appealed to me, I guess I'm getting old! My car is exactly the same as Stanski's. In fact maybe it IS Stanski's, I bought it from a dealer in Derby last October. It has been fantastic btw, smooth and wafty in the traffic and then very reminiscent of the Zed when you want it to be! If you've got any questions just let me know.

Next time you hear the squeak try moving the seat belt socket (the bit attached to the side of the seat) forwards or backwards on its pivot. I had a squeak which took me ages to find but it turned out to be the seat belt socket joint!

When mine went wrong I spent hours reading so many stories of people with this and idle problems all over the world. Nissan garages don't have a clue and many people have replaced the throttle body(ies) and ECU only to find it hasn't fixed it. One guy bought three different throttle bodies, ECU re-flashed, new ECU, then just happened to try his old throttle body while waiting for a forth, Suddenly the idle air volume learn just worked and he was back to normal! I guess what I'm trying to say is - hang in there and hopefully NDS will help you sort it. At least you can run it multiple times easily rather than pressing pedals all day. I've come to the conclusion that the Nissan "idle air volume learn" is, for want of a better word, @*!#! They use it on a whole range of their cars and you'll find the Internet full of horror stories. It might work when the car is in the factory but once the engine ages it doesn't seem fit for purpose. Unless you have an actual error code relating to the throttle body then I don't think they are ever at fault, and I also believe it's nearly impossible to damage them by cleaning them. Nissan stealers seem happy to throw new bodies and ECUs at the problem though but Nissan themselves must know the nature of the problem by now? Either the garages aren't informed or they are aware but would rather sell you parts (£££) than do a proper diagnosis. Rant over hehe! Good luck with it though mate, I know how frustrating it can be.

If you are in the south west I'd recommend these guys http://www.gocool.co.uk they've repaired leaks for me before and are mobile so it can be done at your home or work place.

The reason I ask about the ODB is that there's an Android app available which will perform the idle air volume learn at the touch of a button. Much easier and it was the only method which got my idle to normal. Search the forum for Nissan Data Scan or NDS. I think you're right about the 350GT, engine wise it's the same as early Zeds albeit the JDM version.

Aww annoying. At the point when you start the car during the idle air volume learn do the revs drop down to usual idle speed for about 10 seconds, then "give up" and return to surging? If so it could be the learn is being rejected. A few more things you must satisfy: Engine should be at normal running temperature. Steering wheel should be perfectly centred. Also, do you have access to an ODB interface? A cheap Bluetooth one will do.

Just disconnecting the nagative terminal will do. When I had this problem the silly revving only occurred once the engine was warm but didn't happen after the battery disconnect and idle to warm. Hopefully you'll get the same.

I had exactly the same problem on my Zed after cleaning the throttle bodies. The idle air volume learn is impossible when this is happening. Bit of a brown trousers moment but I managed to resolve it by doing the following: Disconnect the battery for a long time (2+ hours) and ensure the engine is completely cold Re-connect the battery and turn everything off (fans, lights, radio etc) Start the engine and let it idle for a long time (20+ minutes) until the engine gets up to temperature, don't rev it or touch anything At this point hopefully you'll have a stable albeit high idle Perform the three learning functions listed earlier in this thread (idle air volume may need multiple attempts) Hope you get it sorted!

NDS III is for 2007 onwards I've got this and can't get it to connect? What Bluetooth ODB interface are you using?

Btw it seems the Lite versions have the same functionality but they have advertising on them.

Did the procedure report a failure or did the timer just keep counting forever? Did you make sure all of the required conditions were met? So, fan, radio, all lights etc switched off, doors closed and steering wheel set dead centre? If so, I would try running the Clear Self Learn function. I'd recommend getting the engine nice and hot, have the ignition fully on but engine not running, then run the clear function. Then start the car and try running the Idle Air Volume Learn again. If it reports a failure then try a few more times, it might not work the first time. If it still fails then try checking the following in the data monitor before you run the learn: Heater Fan Switch: Off Park/Neutral Switch: On Power Steering Switch: Off Electrical Load Signal: Off If any of those registers show differently then I think it will cancel the learn. I've read of a few people having problems because of a faulty power steering pressure switch for example. Good luck, hope it works for you!

A list of all of the parameters I can see in the app with my car is below. I can't see oil pressure, though there is oil temperature but as far as I know there isn't a sensor for that on the 350Z. Maybe it has been misnamed?
