The new one comes with basic instructions but this is similar to my other MB products. Some screws hold the under dash cover on. Remove them, pull down, unplug light and air temp sensor, remove cover. Unclip cabin air filter, pull out. That's it. The one in the car was fairly clean and was MB. The Hengst I put in is definitely a cheaper, lighter construction. I may run MB next time.
Replacement interval is 20k I believe, or every B service. That makes it due at 100k. It's at 98k.
