Was coasting up to a stop light last night and the car started shuddering, thought I popped a tire at first. Went to pull away from the light and the car was shaking bad running on 4 cylinders or less. Further diagnostics today shows low compression across the board and impacts on the #2 piston. Need to tear down to fully diagnose, but it's not looking good. Sad thing is I sold my spare S8 motor last summer when I was moving. I still have a spare 40v A6 engine, so I might be able to salvage the head and valves from that so long as there's not damage to the bores. Guess I should 6spd swap the car while the engine is out too haha.
