So I work in Walmart in their TLE and I had a 2012 Volkswagen Jetta come in for an oil change. Now I’m not familiar with any VW car so I was relying off our oil guides and filter guides. Our filter guide said the car took a canister filter a fram 3614 if I remember correctly. I go under the car to change the filter and don’t see a canister type filter anywhere but I see what looked like a housing for a cartridge type filter. Now this was attached to a gray box that didn’t seem to connect to anything. I start removing it and oil just pours out and it doesn’t have a filter on it. I tried to put it back on and I could not get it to go back in and screw into place. Took another guy about 10-15 minutes to get it back on. Filled it up with oil and checked if it was leaking from there and there were no leaks. Anyone have any idea what this was?
