I should probably ask this question tomorrow after I have a chance to see the whole area with adequate lighting. Is this sleeve a part I should be able to order from the dealer and replace myself without having to rip out have the front of the engine components to get to the base of the sleeve? Do you need to get under the car to replace it? It's an AGU 1.8T engine. Anyone have a VW or Audi part number that should work? VW parts and mechanics are much easier to get a hold of where I live.
Is it possible to determine if any of the yellow plastic parts fell into the oil sump without taking it off and apart?
