    ok looking on google iv got that cylinder 1 is maxed out and cyl 2 could be low cos its trying to compensate,just need to figure out what would cause that,google searching i have figured

    worn cam
    low compression
    faulty injector loom
    pourus head

    any one else know of anything that might cause this

    Looks like the age old injector failure. IIRC there is some kind of action where Audi replace the faulty units with new improved ones

    the strange thing is though i have already replace the injector in cyl 1 and the mechanic said when he took them out that the injectors had already been done before that cos they were exchange units.
