I have changed the cabin air filter in my 2016 GTI.
That’s right, it only took me about 15 minutes to figure out how to open the cover for the filter. That should take about 10 seconds. The FSM helpfully says push down and out, and I only half-broke a plastic tab when trying to figure out what physical combination actually made it move in that direction. As with all such things, next time should be super simple, now that I’ve done it once. At least I didn’t struggle to get the glovebox in the service position.
I’m still waiting for RockAuto to deliver the engine air filter that was supposed to arrive on Friday. I’d like to think that replacing that will be even easier, but I’m not going to over-estimate my abilities.
