    That shouldn't like that, looks like the engine is pulling over a lot of oil.

    whats your oil consumption like?

    I cannot see the pics but afaik it is common enough but going by robin's response you might have an excessive amount

    the boosts pipes/intercooler pipes need to breath so will spit some oil residue - you would usually find this at the front passenger side inbehind the fog light

    When I had my MOT I took off the underside sump tray and it was caked in oil and muck after 4 years of driving so just cleaned it

    looks to me like its been doing it for some time now judging by the amount of **** stuck to the belly pan plastics,

    it runs fine with no smoke

    i have only owned the car for a few weeks now so cant tell the oil usage?

    IMO that isn't that bad.... What kind of mileage has the car done? Is it chipped or running higher boost than normal?
    Do you drive it hard? I wouldn't be too worried.

    It looks more like residue than fresh leaking oil to me and a build up over many miles.
    I would probably (carfully) jet wash it off with engine cleaner applied and keep an eye out .
    Guess it could be slight vapour leak over many miles with oil haze?..

    Mine has done the same amount of miles and the belly pan and lower intercooler pipes look in the same condition.
    I just cleaned them off, however I did disconected the boost pipes and no oil dripped out.

    It looks normal for that kind of mileage. I had a Golf with the 1.9 TDI engine and it was similar. I would check the joint in the second from last picture though, it doesn't look straight to me and could be coming loose.

    As the other posters have said, clean it off, it's then easier to keep an eye on to see if there are any fresh leaks.

    At that mileage you would probably benefit from cleaning the EGR valve, there was a recent thread on this: help on 2.0TDI engine
