    They are different to each other if i remember right the top one has 5 wires and the bottom 4 but it could be the other way round been a while since i did mine

    Deffo different.

    Had a quick look on euro car parts, but they don't stock a wideband pre cat sensor sadly.

    Both egt and lambda contribute to bad fueling and loss of power

    Having a quick look at some of those codes seem to come up as 'short to ground' as a common description...

    Judging from your ECU 01314 error I am of a mind that the cause of a lot of these errors are due to the ECU picking up another problem
    01314 - Ross-Tech Wiki

    Also digging around I found this..
    VWVortex.com - got 8 codes 17880 17833 17525 17843 etc

    Has some similar codes to yours... all the posts seem to suggest fuel pump relay for some reason... thats a start point at least...

    Google is your actual friend btw ;P

    I think at this point my friend its worth taking it to a specialist...

    O2 sensors are lambdas... fuel pump relay should be under the dash drivers side IIRC but no idea what one...

    I would personally get the car checked over by a qualified auto electrician as all the faults you have appear to be the result of a larger problem... I suspect if the initial problem is fixed then most of the other faults should clear...
