    Cabin fan not working on 4

    I had the exact same issue occur on my old VN Executive, whereby the fan would work on speeds 1, 2 and 3, but then started working intermittently; then not at all on speed 4. Turned out to be a melted terminal on the fan relay base connector, which was making intermittent contact with the actual...

    Vz 05 wagon shuttering

    Obscure long shot here, but if the 'shuddering' is basically occurring under acceleration, then it might possibly be a tail-shaft centre bearing issue (deteriorated bearing housing rubber). Simply enough to check, to eliminate this issue.

    2004 vz misfiring

    I would agree with your explanation EXCEPT: the OP has indicated that at one stage, the problem appeared to have disappeared for a while, then re-appeared. If your theory was correct, then I would expect the fault should show up consistently and continuously (a missing/damaged reluctor tooth...

    2004 vz misfiring

    I hate to say this, but with all the fault-finding steps you have already taken, this is really smelling like a wiring issue in the ignition coil circuit or an issue in the ECU. :(

    Can I Put An Auto Motor In My Manual VZ?

    And while you are at it: with the engine out, give the thermostat a thorough inspection - perhaps even just replacing it on spec while the engine is out and everything is accessible.

    Vz misfire and injector circuit issues.

    After 42 years as an aircraft and ground support equipment electrician, this statement is a new one for me, and goes against every electrical theory known to mankind. What would burn out/give drivers a hard time is excess current flow though them, which would occur with a short circuit to...

    Cloned tech 2 scan tool

    I would suggest an extra two '0s' on the end of the 50, if you are referring to a genuine Bosch Tech2 unit.

    Changeover VY engine blows smoke on start up had engine only 5 weeks

    A real long shot here: is it possible that any of the 'popping'/'backfiring' may have damaged the PCV? It might possibly explain some of the issues here. Like I said, a reallllllly long shot here.

    Rear light Fail

    If there are no obvious faults, it may just require the rear light failure system 're-learn' procedure to be carried out in the first instance.

    VZ Executive Factory Gas converter replacement?

    I had a similar issue with my LPG installation. Long story short, it turned out to be a faulty temperature sensor that is fitted into the LPG reducer (converter) assembly. The replacement cost around $60-70. I did get a quote for a new reducer assembly, and it was in the order of around $500...

    How does VZ fare in overall reliability?

    I know. Just keeping up with it myself. :)

    How does VZ fare in overall reliability?

    To reply directly to you: Replacement engine is still working, however I don't know how long it will last, as I am running factory LPG - and I believe my replacement engine may not be totally LPG compatible. Hence, I'm looking at 'moving' this vehicle on, before I have any more Alloytec dramas.

    How does VZ fare in overall reliability?

    1. OP (long gone by now) asked if there were any issues with the VZ - specifically the Alloytec V6. 2. I replied that there had been numerous issues (threads) reported with overheating issues with the Alloytec. 3. I added that I have experienced these overheating issues with my VZ...

    Actually that is one thing we do agree on. LOL I wonder if they did actually buy a VZ?

    How does VZ fare in overall reliability?

    Yes at all. I stated that there is a regular recurring theme of overheating/cooling system issues, and the number of threads seem to confirm this. Just count them yourself to be sure. As for my engine - no-one could solve the overheating issues I had, even after a thermostat replacement, by a...

    So, where did I say it was common? And where did I say I cooked my engine? Making up a bit of stuff there.

    How does VZ fare in overall reliability?

    The sad part is, the vehicle itself was great - I've had two Commodore wagons in a row (VN & VZ), and they are brilliant as far a driving them is concerned. As far as my old VN was concerned, well for me it lasted until around 350000km, with everything worn out, but still going OK (in fact the...

    How does VZ fare in overall reliability?

    On my Alloytec, it was a major issue - %100 so. When an engine basically fails with overheating/cooling system issues at less than 130000km, then it is an issue - especially reinforced by dollars spent trying to solve the issue. Say what you like pal, at the end of the day, it was the issue for...

    How does VZ fare in overall reliability?

    Alloytec cooling systems failures appear to be a recurring issue. Having personally experienced it myself, it is a major failing, and one that should never have arisen as frequently as folk seem to be experiencing (check out the number of forum threads about this issue). I'm sure that there...

    Dual Fuel won't run on gas?

    Hi mate. I just had a more in depth look at the breakdown of the reducer and it appears that, as the sensor has an O-ring to seal it into the reducer body, it may in fact break into the low pressure outlet side of the LPG system. BTW, that sensor you refer to in your post is not the LPG sensor...

    Dual Fuel won't run on gas?

    I had the exact same issue with my 2005 dual fuel VZ V6. It was a bastard to track down the fault, which eventually turned out to be a faulty LPG reducer temperature sensor - this sensor detects the coolant temperature and lets the LPG ECU know when the coolant temperature is high enough to...

    Diff oil myth

    Why? If the vehicle is traveling normally without a lot of hard turns, then the actual 'differential' action will be minimal. I don't see how this would require extra hp or affect fuel economy much, as the 'spider' (side) gears would be carrying out a minimum of differential action. You could...

    vz commodore cranks and almost starts, then dies

    If the VZ ECU has an 'unloader' function similar to the VN ECU, starting a flooded engine can be achieved by holding the accelerator fully open. This should command the ECU to enter a 'clear flood' mode, by deactivating the fuel injectors, allowing excess fuel to be cleared more quickly during...

    Keyfob airal or nob thing

    Unfortunately, the site you are looking at quotes P/No: LR2032 (an Alkaline cell), whereas the description and the actual picture of the item shows P/No: LIR2032 - which is the rechargeable Lithium type cell. Granted I can see how you are confused, as either the site title part number is...

    Keyfob airal or nob thing

    Mate, this is where you are getting confused and completely unraveled. Part Number LR2032 is NOT the same as LIR2032. Prefix LR is for an alkaline cell, whereas LIR is for a rechargeable Lithium type cell. After being in technical procurement and purchasing for over 20 years, the ONLY part...

    Yes, your original statement is completely wrong.

    Keyfob airal or nob thing

    Have a look at part number on the item the website shows - it's not rocket science. Also your original quote quote that 'LR' indicates a rechargeable cell and 'CR' indicates a non-rechargeable cell is completely wrong. End of story sunshine.

    How to Remove VZ Driver's Seatbelt

    So, if it has been involved in a major accident and been stretched by extraordinary forces due to restraining an adult body, you would be quite happy to use this belt again? Or what about if the belt has ever been exposed to any chemicals or harmful substances at all (eg cleaning chemicals)...

    Keyfob airal or nob thing

    Not quite: The 'LR2032' you quoted is actually a 'LIR2032' - a completely different thing altogether. It is even described in the downloadable datasheet on the site you linked to. As per what I stated before: the 'L' designation in the 'LR' series of cells is for the alkaline chemistry...

    Keyfob airal or nob thing

    Where on earth did this come from, and can you provide a web-link, as it sounds extremely doubtful. As an example: an LR44 battery is an alkaline type cell which is certainly not generally rechargeable - ie is regarded as a primary cell. Attempting to recharge one could lead to some rather...
