A few weeks ago I had a shop change the oil in my 00 Passat ATW, and yesterday the oil filter backed off. I was driving and noticed my oil gauge dropped right to 0, then the STOP light came on and I immediately pulled over. Lucky enough I had extra oil, and knew how to spin the filter back on.
It looks like the pipe that goes through the cooler they tightened it into the filter with the big locking nut. Is this how its supposed to be? Whenever I did my oil changes the pipe always stayed where it screws into the cooler, now it unscrews and stays in the filter. It stripped a coupe threads out of the block/cooler, but I backed the pipe out of the filter some and screwed it back in.
No damage to the engine from what I can tell, just lost lots of oil. I havent driven the car yet, I want to make sure I put this pipe on correctly. This one time I didn't have time to do my oil change, so I brought it to a shop.
