Agree with M5S5 - unless you had a turbo bust loose and drench the entire exhaust with oil, I can't see all 4 going at once. They may be OK, but something else is causing them to throw codes. Get all the info you can from a VAG-COM and post it here. Could even be the heater line to the sensors has broken/quit/??? - only the codes will tell us...
