    Hi all
    So I have recently changed the injectors in my 04 viano due to it not starting, black death on injector 3. All went well I thought however the replacement second hand injectors although seemed to work the van was kicking out lots of black smoke and running poorly. Do injectors need to be programmed?
    Next I have noticed a lot of water outside on the floor left side if you were sitting in the van, and also passenger side foot well (uk). The water feels slick like not just plain water too. I've heard horror stories of piercing the water jacket, would this cause water to leak like this, inside and outside the van.
    Now assuming it is a pierced water jacket is there a way to repair it in situ, I have read about jb weld, can someone explain exactly what to do.
    This van isn't worth spending the money on so sending to a MB garage is not really a option.

    I can answer your first question. Yes injectors do need programming into the onboard controller.
    Unless there is an automatic way they can be programmed.

    Not sure on an 04vito. Early cdi don't need to be programmed. Later ones have a number in a circle that needs to be programmed.

    It then gets more complicated from then. Take a picture of the injector and we can tell.

    Talking from torment at start of year from injectors on my vito, wether they need programmed or not they should still be running black smoke free, just lumpy I found in mine if they need coded. Probably best to get codes read and if nothing points there leave the injectors in to get tested if they are not reconditioned ones. That will probably cost 60- 80 quid for the proper test but some diesel specialists do a quick test for a lot less. I got a faulty injector in a recon set I put in mine.

    Alexander will keep you right as him and other guys on forum here pulled me out of manys a hole :)
