Welcome to the Z!
I had the local lube-retard tell me (I have a shop do the change, but I supply the oil cuz I live in a condo and can't do it in the parking lot myself
) that it was time to change the cabin filter on my '07 cuz that's what his computer told him. He tried to argue with me that I had a cabin air filter and it needed to be changed... I had to prove a point. I asked him how many screws are there holding the dash in place, of course he had no answer. The answer is 63, I know cuz I've disassembled my dash 3 times now... so I'd know if there was a cabin filter back there somewhere.
