Welcome to the new look VWWatercooled

After much work and little sleep there is a new version of the forums running on more powerful and recent hardware as well as an upgraded software platform.

Things are mostly the same, but some things are a little different. We will be learning together, so please post questions (and answers if you've worked things out) in the help thread.

The new forum software is an upgraded version of what came before, it's mostly the same but also a little different. Hopefully easier to use and more stable than before. We are learning together here, so please be patient. If you have questions, please post them here. If you have worked something out and can provide an answer,

    So it was the ECU all along. Oh well, hopefully it will run forever now and you won't get any more mystery problems to solve on it. Sounds like you might have spent more time on it than the whole vehicle was worth

    Just curious, if you got another similar problem vehicle, how would you go about diagnosing this time around (assuming you didn't have a replacement ECU readily available) ?

        Some golf 3 have 1 window in the diz and some have 4, same goes for the Transporter. The 1 window is only a No1 reference point in conjunction with the Crank angle sensor. Great to hear its running, and yeah a good lesson for anyone trying a diz on their Golf 3 too as this is also the case. Some have G28( crank sensor ) and some dont.
        Anyway it does feel good when you crack it hey. Obviously all who have posted including myself assumed all the bits being tried were the same.
        Ah well it goes, thats the main thing, there is always one that will test ya and like you say its the favour ones that normally do!!!!!! Been there got the hat,pen teeshirt the lot hey LOL

          I`d be very careful about test units being exactly the same.

          I would use my trusty LED stuffed in the fuel rail connector to check whether the injectors were pulsing. With the dodgy ecu it does not pulse, but does dump fuel when you stop cranking

          I reckon checking and rechecking the basic is the key to most problems.
          And hey every day is a learning curve, its good to learn things.

            Yes, that was rather misleading, wasn't it
