    Whats the year/model of the car?

    If the oil light has come on then something could have been starved of oil (turbo bearing, engine bottom end etc) any mods on the car? boost gauge so we know what boost it was running and what it is now? have you had the car scanned for fault codes?

    Sounds like a leak somewhere mate have checked that there are no pipes loose or have popped off? Failing that drive it easy or call a garage, maybe it's also gone into limp mode I had this problem on my golf before I think the oil feed pipe gets clogged and causes low oil pressure light to comes on , but it's a easy fix so drive it easy till u can sort it mate

    So its an S3 then? what year?

    First things as said are to check all rubber pipes/hoses for leaks... typical ones to go are the hoses under the inlet manifold... typical signs is oil... oil should be inside the engine not outside... if the hoses under the inlet manifold are oily then chances are theres a split (or has been in the past)

    Get the car scanned for fault codes preferably using something like VCDS as handheld and generic scanners tend to not give all the detail...
