It is important to replace engine air filters on a regular basis to ensure that clean combustible air is going into the engine of you Passat. Refer to your maintenance schedule to determine how often and under what conditions you should replace it. Replacing it yourself is pretty easy, and you can save on labour charges from the local repair station or dealership. Buying a high grade reusable air filter is expensive, and the jury is still out on the exact benefit it offers the vehicle. A medium disposable grade air filter is just fine, and if you're replacing it on a regular enough schedule, you can also save money on the expensive cleaning kits for the reusable types.
